My old Corsair HX1000 has a toggle switch right on the unit to switch between multiple and single 12v rails. This isn't new and I don't understand why they're advertising this as "overclocking". I think they should just better educate users on the difference between single and multiple rails.
Do you know why they call features by bad names ? Its marketing 😂 having psu that can switch between rail usage sound booooring. Overclocking psu sounds like something extra
My understanding is it allows to push more power to one source so with OC mode on the device pluged to 12v2 for example will be able to draw more than 80 amps instead of 40 in non OC mode
Multi rail has each 12V group (rail) protected individually, if any of them draw too much the PSU shuts down. This is to protect individual components, but it also means a component that wants a bit more power as normal operation shuts down the PSU, while really the power supply has plenty of headroom because none of the other rails are drawing max power. Single rail combines all the groups, so individual components don't trigger protection, but total power draw still does. I think originally you actually had multiple rails because power supplies had separate circuitry for each that really couldn't handle more. Modern supplies however have the multiple rails are an addition that isn't really needed for the PSU itself, though load ballancing might improve efficiency or something. In practice however no-one really needs this. Only some extreme overclocking scenarios are ever going to need it. It's one of those "if you have to ask, you don't need it" things. I'm also not sure why Jay makes a big deal of it. This has existed for years and is fairly standard on high power PS's. The only thing special is the switch you can access without opening the case, which in my opinion is a bad idea; it's hard to picture a scenario where you routinely reboot to (de)activate such an OC feature, and if you do chances are you're going to forget switching at some point so you're better off leaving it on the single rail setting when not overclocking.
@@nagranoth_ I think it is important to note that you only switch it to single rail mode when you only have one component connected to the 12v rails. As soon as you have multiple components you risk frying them all at once on single rail mode, correct?
Yeah, I felt like he got distracted by the relay click instead of explaining what the actual point of it is. I started watching the video to find out what it was and left it not really knowing. Thanks to the others commenting to this for explaining it.
@L3v3LLIP think of it like the breaker panel of your house. Let's say you have a 200 Amp main breaker, and 10 20 amp breakers feeding appropriately sized wiring and loads on each. (Of course nobody's generally pulling 200 Amps, but bear with the example). Now, let's say circuit 3 has a device that's malfunctioning and drawing more current than it should. So now there's 30 Amps on that 20 Amp circuit. The individual 20 Amp breaker will "detect" that over current. For a multi rail PSU the OCP (over current protection) detects the excess load on one rail and shuts down the entire PC. In contrast, if you could "single rail" (Overclock, lol) your home's breaker panel, instead of having 10 20 Amp circuits, they'd all feed off the main 200 Amp breaker. You'd still be able to effectively pull 200 Amps in your entire house. However, if one device/circuit is malfunctioning and drawing more current than it should (30 Amps on circuit 3, and let's say 4 Amps everywhere else), the main breaker is going to have no idea that that device/wiring on circuit 3 is being overloaded. Now, let's say you really needed 30 Amps, because you have two appliances. In a house, the right thing to do would be to add a circuit with appropriate wiring to "split" that 30 Amp load across two protection devices, or two circuits. In the PSU world, the "safer" approach is to stay multi rail, and try to balance your loads between the different rails to stay within their limits. However, in the PC/PSU world, if you truly have one device that only plugs in one PSU output that exceeds the current protection in multi rail, you CAN go single rail to work around it, but you're limiting (almost eliminateing) your current protection on your other devices.
@@GameslordXY that's not true, the "modern" protections you are talking about were already implemented by those german engineers, others had to step up to...
Dust is not why the fan ramps up. You need momentary higher voltage to kick the dead weight of the resting fan into motion, then you can apply less power to keep it spinning. Just like starting up a merry-go-round (or a flywheel)...it takes greater force to start movement, then far less to maintain a certain speed.
That's just a sad excuse for not using PWM, as a PWM controlled fan still feeds the full 12V to its motor at all speed levels. There are more reasons for it, like providing a safe default configuration in case the circuit that regulates its speed is malfunctioning, with the short period of going full speed being only the time the control circuit requires to stabilize on startup. NTC temp sensors have a lot of noise so you need to collect quite a bit of data to calculate a more reliable value, which delays the startup time of that circuit significantly, especially if it's using a PID control circuit. Some PSU manufacturers like Seasonic also like to use fans with a type of bearing that needs to passively build up oil pressure while spinning, which may benefit from a fast spin-up to reduce wear and tear.
@@letalissonusdc motor stall current requirements still play into a pwm controlled system. The CURRENT is what spikes when starting a dc motor. Not voltage. Voltage can be effected based on a number of things but it’s not about that here because watts are watts. Even if the voltage drops, the current will go up to meet the watt requirement.
@@letalissonuswhile pwm DOES send the device full 12v all the time, the average voltage seen at the device would depend on the duty cycle. So for example, the average voltage that a 12v fan sees at 50% duty cycle pwm would be right at 6v working average. In this situation, current stays the same. So the result is less watts being used by the motor.
In europe the standard is 230V @50Hz. In Germany houses are wired with 1.5mm (something between AWG15 and AWG16) cables and protected with 16A breakers. So theoretically you can pull up to 3680 watts of power from a standard „schuko“ socket.
@@Mikasicki I might be talking out my ass but I believe most houses do have 220v for washing machines and some people have it wired in their garage but not through the actual house. This is just from my limited knowledge of working with my grandpa who was an electrician, mechanic, and plumber lol so maybe I should go ask him
Here in Africa the sockets are 240v 16A ,the breakers are 20A with 2.5mm (13 gauge) wire so its a total of 4700w per at wall outlet. Our sockets are a bit beefier than European and UK sockets. I don't think this affects PC's as much as it does American kitchen appliances 1600w limit for kettle sandwich toasters air fryers vacuum cleaners were ours are 2200w - 3000w. At least US electric ovens have dedicated 220v sockets, but remember its just the two 110v phases in Delta there is no neutral in US 220v 30a sockets so no GFCI possible on the 220v. What makes American electricity so dangerous is the amperage and lack of GFCI breaker on the entire panel i.e all breakers down stream of GFCI like in it is for us in 220v countries.
The Australian power grid is 230v +10% to -6% (so 253v to 216v), with most power being supplied in the higher end of 240v - 250v. Our normal sockets are rated at 10a, so we normally expect 2,400w to be available at the plug. We do have a 15a rated socket that is backwards compatible with 10a plugs (a larger ground pin prevents 15a plugs from entering 10a sockets), but they are pretty rare in residential properties. I've only lived in one place that had a 15a socket and that was located in the garage.
Here, in India, we use 6A and 16A sockets. 16A is common here for plugging ACs, microwaves, etc. My Corsair RM850x also came with the huge 16A plug, even though it's way overkill.
It's not overclocking. 🙄 It's just a choice between multi-rail or single rail. Which Corsair have been doing for years. My Corsair shipped set to multi-rail, and if you want single rail, you just set it in the software
I always liked beQuiet products, be it their fans, Coolers, Cases or PSUs. Their stuff always feels premium, even the older series. I've been using one of their 1200W PSUs from the older Straight Power 11 Platinum Series, I bought that back in 2020 and it's been working perfectly and as the name suggests rather quietly.
It's honestly nuts how much power one needs in their PC's nowadays When i started building my own, 550w was on the "higher" end, now recently in anticipation for Ryzen 8000's i've bought a 1000w one to retire my current 850w...
Between CPUs and GPUs soon we'll need 20 Amp dedicated appliance circuits in bedrooms instead of standard 15 Amp ones because of the max wattage of the 15s won't be enough. Max wattage: 15A = 1800 watts 20A = 2400 watts
@@jd-py5nm The same happening to me. My 1000w is acting up now with 4090 and 13900k. I'm seeing 900w usage on the watt meter plug and random restarts without any errors. Waiting for my 1200w PSU to arrive now.
Yeah.. I bought my first bequiet back in 2008 or so. It was a P7 Dark Power 650W which felt incredibly over-powered to me at the time. But that thing kept going in the next two PCs I built after that and still works to this day - for all I know. That said: I'm "only" up by 100W now with a Straight Power 12 750W. I really don't think I need more than that for my 14700KF/RTX4070 +a bit of RGB-crap system - and I'm pretty confident I still have some power to spare should I decide to upgrade my GPU to a 4070Ti or perhaps even a 4080.
I am using the dark power pro 12 1300W in my current system and it is awesome. Lasmost no noise, great cables and superb stability and the little pcie thing to turn multi rail to single rail looks cute even though i dont use it
Got the 1500W version for my dream build and I don't expect to buy another power supply for a looong time. I can rest easy knowing my 3090 Ti power spikes mean absolutely nothing to my PSU.
What is bad about BeQuiet PSUs - their top models (1300w, 1600w) are not rated for 100v hence cannot be used in Japan. At the same time quite a lot of PSUs rated 100-240 (not 115-240) including 1300/1600w models though 1600w model will be limited to 1300w at 100v because of current limitation.
@@deadlymecury that's interesting input actually. As a European I wouldn't care for that, but that is definitely a dealbreaker to mot have that work in japan
I'm using the Be Quiet! straightpower pro 12, 1200W (straightpower are single rail psu's) and before that I had the dark power pro 11, 850W. Solid psu's, never had any issues with them. Really great psu's, solid build!
I'm glad this isn't "overclocking" in the sense that I imagined. If a PSU is not operating within spec, then it is a magic smoke machine that makes bricks.
I had the ASUS Thor 1200w (version1) psu and had nightmares since day 1 with my water cooled motherboard+cpu with a stock 3090ftw (transient spike issues well known now but not so known then). Two weeks ago I switched that out for the 1600w Dark Pro. It’s rock solid. Is 1600w overkill? Yes, but since it’s rated to be able to handle double that wattage on spikes, even the 3090 is happy.
220V at 13A theoretically gives 2860W for the UK. We can buy and just plug in on a standard UK socket 2.5kw heaters. Heaters and Quick boil electric kettles tend to be top end power normal consumer electric devices
Can UK outlet socket supply 13 A continuously though? We have schuko outlets here that can give up to 16 A but only 10 A continuously unless it's super schuko which are used in car heating poles for example.
@@Simon_Denmarkyes, UK sockets up to correct spec can deliver 13a continuously just barely. The UK originally was a 250v system, but changed to 230-240 to match most of Europe. So 3kw is the technical maximum power an outlet is allowed to provide
It's strange for me that most US powerboxes (the mains supply) has a limit on how much power they can give. Some states in the US are now having power splitters at the house so you can have 220 and 110v. I guess when you live in a country that doesn't use a kettle to boil water for tea, the rest of your devices have to suffer.
@@kamelionify The US power grid is 240v using split phase. We supply 120v to most outlets in a house because that is what most devices use, and from a shock standpoint it's safer. Also your suggestion of the kettle doesn't really apply. Most kettles don't take anywhere near enough wattage that a 120v outlet can supply. TechnologyConnections did a great video on the fact that there really isn't a difference. In most American households the highest wattage devices are typically things that won't be moved, dish washers, laundry washers & dryers, so therefore it makes sense to install the specific higher voltage outlet at that location. Ultimately the usage was based on the applications needed, in which its available but not always necessary.
Hi Jay. Well, you've done it to me again. My wife came into my Gamer Room while I watched this video. She noticed it was one of your videos and said, "What's that SOB telling you to buy today?" I hope to have my 'new' PSU in a few days. I love my wife and she is right up there with my PC.
I've been looking at the 1300w for a while now. Glad to see someone that I recognize and trust do a video. Been using the same 850w corsair for like 11 years now.
I'm running a Corsair 750W PSU that's fairly new, but my case, cooler, and fans are all Be Quiet. I plan to get their PSU as well, but probably the Pure Power 12 1000W option.
I have the dark power pro 12 1200w unit. The only thing I dislike about it is the size of the cables. As nice as they are, you can’t find combs that fit them.
Jay, I still own an old Antec power supply that has three knobs to "overclock" the voltages on +3.3, +5 and +12V It was really helpful back then. I had a Maxtor HDD that kept turning off and on on voltage fluctuations and cranking up +5V IIRC fixed it 😁
There's no reason for it not to be a single 12v rail in the first place like the EVGA Supernova, which makes the whole "overclock" thing nothing more than a gimmick.
I have the Dark Power 13 1000w and can't recommend it. Yes, its really efficient and has all the bells and whistles... but its quite obnoxious when my pc is in idle. Its by far the loudest component when in Idle because it doesnt has a no fan mode.
just make a gasket between the power supply tunnel and the unit itself. The power supply cover resonates with the fan!!! I have already done this trick with my power supply, and I wish the same for you.
In Australia where we run a 230v power grid. Well, 230v +10% / -6%, so 253v to 216v delivered to the home. Many grid power providers tend to supply on the high end, between 240v and 250v. Our normal power sockets are rated at 10a. So as a base rule, we assume 2,400w of power available at the plug. We do also have some sockets rated for 15a, these look almost identical except require a larger ground pin which prevents them from being used in a 10a socket, but allows 10a plugs to work perfectly fine in a 15a socket.
I find it a little goofy how we went from single-rail AT/ATX PSUs in the old days, to multi-rail PSUs in the 00's, then back to single-rail, and now back to multi but with single mode as a toggle.
I have a 1k psu from when I had my 980ti with 9590cpu. Now using a 3070 and a 8700k. Works just fine for my system. Had the same on for a really long time now. Probably 8 years old now
My Dark Power Pro 11 750W has this and it's about 6-7 years old. I have the jumper always installed and have the toggle in the box. so this isn't new at all, but thanks for the nice explanation! ;-)
In Europe we have circuits with 230V and mostly 10A fuses but some have 16A like (Germany) which equals to 2300/3680W but obviously you can't feed the full power to the PC due to conversion losses.
bequiet is not known to be a quality psu brand i would rather get corsair, seasonic or evga (if you can find one) but the feature set on this one is quite interesting
I got the 1000W variant during BF, and even though it doesn't look sexy I wouldn't replace the 12vhpwr direct cable. The included cable snapped in audibly and didn't seem to have any way to pull out as was demonstrated in the past. Also it has the bendable high gauge cables as was demonstrated in the video. Overall a really good purchase (and a great price during BF sales anyway)
In Germany we can go up to 3600W if we have the correct connection. If your house/apartment block has been built after 2017, it will be able to do this.
3680W would be the absolute limit we can pull from a single breaker in europe. Usually no more than 2400W, a 12A breaker is pretty common for regular circuits.
Interesting, here in Germany I never saw a 12A breaker. We have usually either 10A (for light circuits) or 16A (for circuits with power outlets) breakers.
@@Drumonymus Unless I'm drunk, I'm pretty sure my panel has only 12 and 16A breakers. Also could be wrong tho. Last time I popped a breaker was end of last year. I'm sure I swaped that pesky B12 for a C16 breaker supplying the work room.
@DrakkarCalethiel I didn't say you were wrong, I just said I don't know it. Didn't mean to offend you. The "Interesting" was not ironic or anything :) in which country do you live?
@@Drumonymus Gee, lf I would get "offened" by this, I would have to reconsider my life. xD Austria, your alpine neighbour. :D Just looked at my panel out of curiousity, 16A bathroom dedicated for the washer, 10A bathroom power + light, living room + entry room 12A, kitchen 3ph16A dedicated for the oven + 16A, sleeping room has a very odd 13A breaker and 12A swapped to 16A for the work room. The only thing that is totally weird is the 13A one. Just why?
Some power supplies (MSI MEG Ai1300P for example) have a usb connector allowing them to be monitored via software. Mine allows you to switch between single rail or multi rail via the software that monitors it.
I have this psu, but 1000w version. First one needed to be returned, but the replacement one works great! Mine doesn't have individually sleeved cables though, so that might be a 1600w only thing (or 1300w).
I had the 1000W version twice and returned both. The fan in both devices were clearly audible even at idle load and louder than all other fans in my pc. In fact, you can hear this rattling even when the psu starts up in the video.
Titanium PSUs are ONLY maximally 94% efficient in the US where they use 110 Volts AC, in Europe (or pretty much everywhere else in the World) where we use 240 Volts it has a maximum of 96% efficiency.
In fact, in Europe it is one of the most reliable power supplies I have been using the Dark Power Pro 11 750w for 4 years without any problems 850w are sufficient under normal conditions without overclocking, otherwise at least 1000w and preferably 1300w Dark Power Pro
Forward compatibility is exactly why I got an 850W PSU. Higher than that and I'll cook in my room, so this is the limit anyway and even with a 7900 XTX and a 5950X I still have 150W left (at it's still getting too hot anyway...)
Power supplies, power stage switches, and rectifiers being rated to handle transient load spikes of double (or more) the safe rated throughput is not special, it is completely normal for all but the absolute cheapest units and is often considered a safety feature, not an overclocking feature.
1:39 230V and wall outlets are 16A, so technically we could use 3680W from outlet but in reality that would be dependant on other devices etc... each room has its own fuse, and kitchens have multiple, lights run from separate 10A fuse
I'm pretty sure that 230 V is used pretty much everywhere in EU, it's the EU standard. Also depends on the outlet type, normal schuko for example can only supply 10 A continously unless you want to burn the socket.
@@Simon_Denmark 230 is writen but try to mesure it. 240. Lowest during "rush hour" is like 238v. And btw schuko is german plug made for 2,5mm cable and 16amp. Standart for schuko is B16 braker which can do up to 30 amp for small time period. 10 amp is for 1,5mm cable and it is usualy used for lights and not for plugs. There is also 2 and 6 amp breakers for lights but those are usually used for single light outside. 2 amp for led and 6 amp for up to 1000w halogen reflectors.
@@Simon_Denmark it can, and its doing it in million and millions of plugs all over europe for tens ano tens of years. maybe you are confused between AC and DC.
Who remembers the old OCZ Power Stream line up of PSUs? We are talking of PSUs who had a 3 small pots on the back for you to adjust 12V, 5V and 3.3V directly to compensate for voltage drops during OC. This was back in the AMD Athlon 64 / Intel Pentium 4 era, so Skt 939 / 478. I had one. Heck I think that I still have it somewhere. Together with their OCZ memory voltage module.
I just had a dark power pro 12 1200W literally blow up, I bought mine new and I had only used it for a year and a half. It ended up taking my power strip with it but fortunately nothing else. Since this is the first time I've ever had a PSU die me it's going to be hard for me to trust the longevity of Be Quiet's PSUs moving forward. That's not to say the PSU was bad while it was working though, it was always silent and did a good job feeding my 12700K + 3080ti system. Also whatever built in protections definitely did their job and prevented the PSU from taking anything inside my computer with it. So far the RMA process has been fairly smooth, but we'll see if I'm even able to get a replacement since I've seen mixed feedback about Be Quiet's RMA support. Anyways, just wanted to share my experience. Might update if I get a replacement.
EU plug can go to 2400W if it's wired for 10A or 3840W with 16A so in europe you could consider up to like +3KW PSUs The click is just bypass relay for the termistor to limit charge current of the input caps and the switch is probably run at like 5v I would imagine nothing fancy just signaling to PSU that's it should pull the trigger for big power
Many power supplies are most efficient when loaded to about 70% or so. So if you buy a 1200W PSU and your system only pulls 450W, it will (possibly) run less efficiently and cost you more on your power bill. Some manufacturers provide a load vs efficiency curve that you can consult.
Probably why my energy bills are so insane 😂 I have a 3080, 7800X3D with a Corsair HX1200 A ton of RGB though and about 12 different peripherals including joysticks and pedals
Our breakers are typically 16 A, so theoretically we could go up to 3.6 kW PSUs. Of course, that's assuming an impossible 100% efficient PSU. And a reserved circuit for just that outlet.
The galax hof uses 2 12vwhpr cables I doubt you would need 2 separate cables from the psu side but hey this psu can do it if needed , that’s pretty cool
i went seasonic again. havent heard a thing from my old or new psu. the rail toggle is neat but really should just be a switch on the psu like fan control toggles are.
If everything in my system drew max wattage, I calculsted 570 watts. I could have put in a 650, but I prefer to over power every build in case I add or upgrade something. So, I put an 850 in. Future proof 😀
Next we’re gonna be overclocking our cardiac pacemakers
I would totally do that
Yeah, I bet that mode will taste like pineapple......

@@letalissonus It's possible that complexities like PWM are a bit risqué to the economy and longevity of a reliable PSU at their present state.
@@letalissonusdc motor stall current requirements still play into a pwm controlled system.
The CURRENT is what spikes when starting a dc motor. Not voltage. Voltage can be effected based on a number of things but it’s not about that here because watts are watts. Even if the voltage drops, the current will go up to meet the watt requirement.
@@letalissonuswhile pwm DOES send the device full 12v all the time, the average voltage seen at the device would depend on the duty cycle. So for example, the average voltage that a 12v fan sees at 50% duty cycle pwm would be right at 6v working average. In this situation, current stays the same. So the result is less watts being used by the motor.
Or it's self-testing
In europe the standard is 230V @50Hz. In Germany houses are wired with 1.5mm (something between AWG15 and AWG16) cables and protected with 16A breakers. So theoretically you can pull up to 3680 watts of power from a standard „schuko“ socket.
1600 sounds really low though. Where vacuums in the US limited to 1600W? That was really not a lot back in the day. Or an electric oven?
@@Mikasickistandard nowadays tbh
@@StimulationSimulated nowaday, yes. But 20 years ago 2500W was more or less standard. Now there are regulations on it if I remember correctly.
@@Mikasicki I might be talking out my ass but I believe most houses do have 220v for washing machines and some people have it wired in their garage but not through the actual house. This is just from my limited knowledge of working with my grandpa who was an electrician, mechanic, and plumber lol so maybe I should go ask him
Here in Africa the sockets are 240v 16A ,the breakers are 20A with 2.5mm (13 gauge) wire so its a total of 4700w per at wall outlet. Our sockets are a bit beefier than European and UK sockets. I don't think this affects PC's as much as it does American kitchen appliances 1600w limit for kettle sandwich toasters air fryers vacuum cleaners were ours are 2200w - 3000w. At least US electric ovens have dedicated 220v sockets, but remember its just the two 110v phases in Delta there is no neutral in US 220v 30a sockets so no GFCI possible on the 220v. What makes American electricity so dangerous is the amperage and lack of GFCI breaker on the entire panel i.e all breakers down stream of GFCI like in it is for us in 220v countries.
The Australian power grid is 230v +10% to -6% (so 253v to 216v), with most power being supplied in the higher end of 240v - 250v.
Our normal sockets are rated at 10a, so we normally expect 2,400w to be available at the plug.
We do have a 15a rated socket that is backwards compatible with 10a plugs (a larger ground pin prevents 15a plugs from entering 10a sockets), but they are pretty rare in residential properties.
I've only lived in one place that had a 15a socket and that was located in the garage.
Here, in India, we use 6A and 16A sockets. 16A is common here for plugging ACs, microwaves, etc. My Corsair RM850x also came with the huge 16A plug, even though it's way overkill.
It's not overclocking. 🙄
It's just a choice between multi-rail or single rail. Which Corsair have been doing for years.
My Corsair shipped set to multi-rail, and if you want single rail, you just set it in the software
beQuiet have also supplied the same switch and panel for their high end PSUs for many years.
Jay just lived under a rock it seems xd
@@Waldherz to be fair, he did say he doesn't do this much bc he doesn't know as much about PSU's as he'd like to.
I always liked beQuiet products, be it their fans, Coolers, Cases or PSUs. Their stuff always feels premium, even the older series. I've been using one of their 1200W PSUs from the older Straight Power 11 Platinum Series, I bought that back in 2020 and it's been working perfectly and as the name suggests rather quietly.
The ca-chunk you hear when overclocking is on is most likely a relay, which you supply power to by shorting two pins on the overclock header.
It's honestly nuts how much power one needs in their PC's nowadays
When i started building my own, 550w was on the "higher" end, now recently in anticipation for Ryzen 8000's i've bought a 1000w one to retire my current 850w...
I bought a 1000 watt back in 2016 its just now starting to act up after tons of use and upgrading of the pc over these years timely video
Between CPUs and GPUs soon we'll need 20 Amp dedicated appliance circuits in bedrooms instead of standard 15 Amp ones because of the max wattage of the 15s won't be enough.
Max wattage:
15A = 1800 watts
20A = 2400 watts
@@jd-py5nm The same happening to me. My 1000w is acting up now with 4090 and 13900k. I'm seeing 900w usage on the watt meter plug and random restarts without any errors. Waiting for my 1200w PSU to arrive now.
Yeah.. I bought my first bequiet back in 2008 or so. It was a P7 Dark Power 650W which felt incredibly over-powered to me at the time. But that thing kept going in the next two PCs I built after that and still works to this day - for all I know.
That said: I'm "only" up by 100W now with a Straight Power 12 750W. I really don't think I need more than that for my 14700KF/RTX4070 +a bit of RGB-crap system - and I'm pretty confident I still have some power to spare should I decide to upgrade my GPU to a 4070Ti or perhaps even a 4080.
My first build used a 65W PSU in 1994. Hopefully things level off soon...we need optical logic gates or some equally massive breakthrough.
I am using the dark power pro 12 1300W in my current system and it is awesome. Lasmost no noise, great cables and superb stability and the little pcie thing to turn multi rail to single rail looks cute even though i dont use it
got the dp 12 1000w its awsome
Got the 1500W version for my dream build and I don't expect to buy another power supply for a looong time. I can rest easy knowing my 3090 Ti power spikes mean absolutely nothing to my PSU.
What is bad about BeQuiet PSUs - their top models (1300w, 1600w) are not rated for 100v hence cannot be used in Japan.
At the same time quite a lot of PSUs rated 100-240 (not 115-240) including 1300/1600w models though 1600w model will be limited to 1300w at 100v because of current limitation.
@@deadlymecury that's interesting input actually. As a European I wouldn't care for that, but that is definitely a dealbreaker to mot have that work in japan
I'm using the Be Quiet! straightpower pro 12, 1200W (straightpower are single rail psu's) and before that I had the dark power pro 11, 850W. Solid psu's, never had any issues with them. Really great psu's, solid build!
I just picked up this power supply,DP13 1000W, and so far, no complaints!
I almost bought the 1300-watt version. Thankfully, I did some digging and realized the 12VHPWR connector is already semi-obsolete.
I'm glad this isn't "overclocking" in the sense that I imagined. If a PSU is not operating within spec, then it is a magic smoke machine that makes bricks.
It's like the old Corsair 1500i power supply. It had a companion software you showed in a video to change the 12V from multi rail to single rail.
Yes, it’s called Corsair Link I believe. My 1500i died after 6 years btw, so I’m not really convinced of the quality of it.
@@LifeStartsAtrpm-ru1xo Dont they also have a 10 year warranty? I'd reach out. Maybe they'll replace with one of equal or higher quality?
I had the ASUS Thor 1200w (version1) psu and had nightmares since day 1 with my water cooled motherboard+cpu with a stock 3090ftw (transient spike issues well known now but not so known then). Two weeks ago I switched that out for the 1600w Dark Pro. It’s rock solid. Is 1600w overkill? Yes, but since it’s rated to be able to handle double that wattage on spikes, even the 3090 is happy.
220V at 13A theoretically gives 2860W for the UK.
We can buy and just plug in on a standard UK socket 2.5kw heaters.
Heaters and Quick boil electric kettles tend to be top end power normal consumer electric devices
Can UK outlet socket supply 13 A continuously though? We have schuko outlets here that can give up to 16 A but only 10 A continuously unless it's super schuko which are used in car heating poles for example.
@@Simon_Denmarkyes, UK sockets up to correct spec can deliver 13a continuously just barely.
The UK originally was a 250v system, but changed to 230-240 to match most of Europe. So 3kw is the technical maximum power an outlet is allowed to provide
It's strange for me that most US powerboxes (the mains supply) has a limit on how much power they can give. Some states in the US are now having power splitters at the house so you can have 220 and 110v. I guess when you live in a country that doesn't use a kettle to boil water for tea, the rest of your devices have to suffer.
Schuko can absolutely handle 10A continuous.
@@kamelionify The US power grid is 240v using split phase. We supply 120v to most outlets in a house because that is what most devices use, and from a shock standpoint it's safer. Also your suggestion of the kettle doesn't really apply. Most kettles don't take anywhere near enough wattage that a 120v outlet can supply. TechnologyConnections did a great video on the fact that there really isn't a difference. In most American households the highest wattage devices are typically things that won't be moved, dish washers, laundry washers & dryers, so therefore it makes sense to install the specific higher voltage outlet at that location. Ultimately the usage was based on the applications needed, in which its available but not always necessary.
Cables didn't get a revision instead if you want a sleeved 12vhpwr cable u have to buy it separately
Hi Jay. Well, you've done it to me again. My wife came into my Gamer Room while I watched this video. She noticed it was one of your videos and said, "What's that SOB telling you to buy today?" I hope to have my 'new' PSU in a few days. I love my wife and she is right up there with my PC.
I've been looking at the 1300w for a while now. Glad to see someone that I recognize and trust do a video. Been using the same 850w corsair for like 11 years now.
I'm running a Corsair 750W PSU that's fairly new, but my case, cooler, and fans are all Be Quiet. I plan to get their PSU as well, but probably the Pure Power 12 1000W option.
I have the dark power pro 12 1200w unit. The only thing I dislike about it is the size of the cables. As nice as they are, you can’t find combs that fit them.
Jay, I still own an old Antec power supply that has three knobs to "overclock" the voltages on +3.3, +5 and +12V
It was really helpful back then. I had a Maxtor HDD that kept turning off and on on voltage fluctuations and cranking up +5V IIRC fixed it 😁
There's no reason for it not to be a single 12v rail in the first place like the EVGA Supernova, which makes the whole "overclock" thing nothing more than a gimmick.
I have the Dark Power 13 1000w and can't recommend it. Yes, its really efficient and has all the bells and whistles... but its quite obnoxious when my pc is in idle. Its by far the loudest component when in Idle because it doesnt has a no fan mode.
just make a gasket between the power supply tunnel and the unit itself. The power supply cover resonates with the fan!!! I have already done this trick with my power supply, and I wish the same for you.
already tried something similiar, but thanks. just sent it back and bought the fsp hydro ti pro. got a real silent build now@@Vadimische
Jay - this is best PSU introduction for a long time. Not as efficient and overdraw resilient as $500+ competitors, but functionally beautiful PSU.
I love beQuiet! Silent Wing fans and knowing that their beautiful power supply is also powers my PC just warms my heart a little
I like that you're talking about power supplies. Don't be afraid to talk about whatever hits you. Makes things interesting.
My Soundcard does the same klicking when starting up the PC. I love it.
Standard for German households are 16A breakers on 230 V -> you can go up to about 3600W
This power supply would be perfect for the Galaxy HOF 4090 since that card has two 12vhpwr connections
In Australia where we run a 230v power grid.
Well, 230v +10% / -6%, so 253v to 216v delivered to the home.
Many grid power providers tend to supply on the high end, between 240v and 250v.
Our normal power sockets are rated at 10a.
So as a base rule, we assume 2,400w of power available at the plug.
We do also have some sockets rated for 15a, these look almost identical except require a larger ground pin which prevents them from being used in a 10a socket, but allows 10a plugs to work perfectly fine in a 15a socket.
you always make my Sunday afternoons more enjoyable. just wish i lived in the States
The latest ATX standard is ATX 3.1, not 3.0. It's the one that updates the 12VHPWR connector to 12V2x6.
In the Netherlands (Europe) we have 16 amps circuit breakers which means we could theoretically go as high as 220v * 16a = 3520 wattage
I find it a little goofy how we went from single-rail AT/ATX PSUs in the old days, to multi-rail PSUs in the 00's, then back to single-rail, and now back to multi but with single mode as a toggle.
It's always nice to draw attention to the PSU and hardware like this certainly does that.
I have a 1k psu from when I had my 980ti with 9590cpu. Now using a 3070 and a 8700k. Works just fine for my system. Had the same on for a really long time now. Probably 8 years old now
Design and Style = 10/10... a very sexy looking PSU... boxing and the corners and the color... perfection.... the logo... 10/10...
My Dark Power Pro 11 750W has this and it's about 6-7 years old. I have the jumper always installed and have the toggle in the box. so this isn't new at all, but thanks for the nice explanation! ;-)
In Europe we have circuits with 230V and mostly 10A fuses but some have 16A like (Germany) which equals to 2300/3680W but obviously you can't feed the full power to the PC due to conversion losses.
the main issue i had with be quiet were 3 failing ones and one actually blowing up
@CalyX. not "big" big but loud as fuck and took down a MoBo with it.....never again
bequiet is not known to be a quality psu brand
i would rather get corsair, seasonic or evga (if you can find one)
but the feature set on this one is quite interesting
Well mine too did a loud boom sound and took my mobo and gpu with it never again
I got the 1000W variant during BF, and even though it doesn't look sexy I wouldn't replace the 12vhpwr direct cable. The included cable snapped in audibly and didn't seem to have any way to pull out as was demonstrated in the past. Also it has the bendable high gauge cables as was demonstrated in the video. Overall a really good purchase (and a great price during BF sales anyway)
I thought the AX1600i had this single rail feature for years.
It has. It’s the same size and I would be surprised if it was less efficient than this new PSU. It definitely has the same rating.
still have my EVGA Supernova 1200 P2 80+ Platinum, 1200W ECO that I've had for about 8yrs where it's still going strong without issue
In Germany we can go up to 3600W if we have the correct connection. If your house/apartment block has been built after 2017, it will be able to do this.
3680W would be the absolute limit we can pull from a single breaker in europe. Usually no more than 2400W, a 12A breaker is pretty common for regular circuits.
Interesting, here in Germany I never saw a 12A breaker. We have usually either 10A (for light circuits) or 16A (for circuits with power outlets) breakers.
12A breakers are actually very uncommon across Europe. 10A or 16A is typical.
@@Drumonymus Unless I'm drunk, I'm pretty sure my panel has only 12 and 16A breakers. Also could be wrong tho. Last time I popped a breaker was end of last year. I'm sure I swaped that pesky B12 for a C16 breaker supplying the work room.
@DrakkarCalethiel I didn't say you were wrong, I just said I don't know it. Didn't mean to offend you. The "Interesting" was not ironic or anything :) in which country do you live?
@@Drumonymus Gee, lf I would get "offened" by this, I would have to reconsider my life. xD Austria, your alpine neighbour. :D Just looked at my panel out of curiousity, 16A bathroom dedicated for the washer, 10A bathroom power + light, living room + entry room 12A, kitchen 3ph16A dedicated for the oven + 16A, sleeping room has a very odd 13A breaker and 12A swapped to 16A for the work room. The only thing that is totally weird is the 13A one. Just why?
Some power supplies (MSI MEG Ai1300P for example) have a usb connector allowing them to be monitored via software. Mine allows you to switch between single rail or multi rail via the software that monitors it.
I have this psu, but 1000w version. First one needed to be returned, but the replacement one works great! Mine doesn't have individually sleeved cables though, so that might be a 1600w only thing (or 1300w).
I had the 1000W version twice and returned both. The fan in both devices were clearly audible even at idle load and louder than all other fans in my pc. In fact, you can hear this rattling even when the psu starts up in the video.
Over here NZ, Standard plug is 10amps so you can pull 2400W, Next size up with the bigger tab is 15amp for 3600W
Power supplys are consumables, They loose wattage over time. It's recommended that you replace your psu about every 2-3 rebuilds
That’s why I got a Corsair HX1200 when I made my original build, so that I wouldn’t have to think about PSU’s for a long time
that power on sound is menacingly cool, i have the 1300 variant
we have the same with dark power 12 (about 'overclock' mode)
really happy about mine on 1000W
ATX 3.0 has already changed, its ATX 3.1 now, 12HPWR was 3.0, new one is 12V-2×6, so this power supply is already "old" stuff)
Titanium PSUs are ONLY maximally 94% efficient in the US where they use 110 Volts AC, in Europe (or pretty much everywhere else in the World) where we use 240 Volts it has a maximum of 96% efficiency.
In fact, in Europe it is one of the most reliable power supplies
I have been using the Dark Power Pro 11 750w for 4 years without any problems
850w are sufficient under normal conditions without overclocking, otherwise at least 1000w and preferably 1300w Dark Power Pro
been using the dark power pro series for more than a decade now, hands down the best psu you can get
wall outlets in europe are 230v and 20 amps so around 4600w max per circuit
I have a 3600 with a 3060-12 gb running on a 450 watt psu without issue. Ran the numbers and I’m still good. Not for much more, but still good.
the dark power pro line has that OC key thing since a couple generations now.
Have the ASUS Rog Thor 850w Platinum and it came with sleeved cables....makes a huge difference
1:35 in the UK the max output of a single socket is 3300w
31 Days of Techmas is so nostalgic to me these days. It's crazy
Yay! Techmas is back. Thanks for doing this Jay. I know it is a lot of work for you and the team.
"Use for overclocking" would be more a better description of that feature.
Forward compatibility is exactly why I got an 850W PSU. Higher than that and I'll cook in my room, so this is the limit anyway and even with a 7900 XTX and a 5950X I still have 150W left (at it's still getting too hot anyway...)
holy shit just seeing that thing, its the prettiest power supply ive ever seen. damn be quiet knows how to make good looking piece of metal
I actually have that exact same 1600w EVGA Supernova in my 7950x machine that I'm watching this video on rn!
Power supplies, power stage switches, and rectifiers being rated to handle transient load spikes of double (or more) the safe rated throughput is not special, it is completely normal for all but the absolute cheapest units and is often considered a safety feature, not an overclocking feature.
1:39 230V and wall outlets are 16A, so technically we could use 3680W from outlet but in reality that would be dependant on other devices etc... each room has its own fuse, and kitchens have multiple, lights run from separate 10A fuse
15:15 PREACH! Lmao, I'm so glad I went to school back when the teachers had sense.
I'm still running a 10 years old Dark Power Pro 10 850W PSU, the Dark Power Pro Series is basically indestructible.
the little click is overcurrent protection, all recent year bequiet PSUs do that.
In europe, we use 240 volt and for wall plugs 16 amp breaker which is 3,8 kw. So max on psu will be 3,8kw (asuming that nothing else is pluged in)
I'm pretty sure that 230 V is used pretty much everywhere in EU, it's the EU standard. Also depends on the outlet type, normal schuko for example can only supply 10 A continously unless you want to burn the socket.
@@Simon_Denmark 230 is writen but try to mesure it. 240. Lowest during "rush hour" is like 238v. And btw schuko is german plug made for 2,5mm cable and 16amp. Standart for schuko is B16 braker which can do up to 30 amp for small time period. 10 amp is for 1,5mm cable and it is usualy used for lights and not for plugs. There is also 2 and 6 amp breakers for lights but those are usually used for single light outside. 2 amp for led and 6 amp for up to 1000w halogen reflectors.
@@michalmichalsk Yep, I’m electrician. The normal schuko still can’t handle more than 10 A for a long period.
@@Simon_Denmark it can, and its doing it in million and millions of plugs all over europe for tens ano tens of years. maybe you are confused between AC and DC.
Who remembers the old OCZ Power Stream line up of PSUs?
We are talking of PSUs who had a 3 small pots on the back for you to adjust 12V, 5V and 3.3V directly to compensate for voltage drops during OC.
This was back in the AMD Athlon 64 / Intel Pentium 4 era, so Skt 939 / 478.
I had one. Heck I think that I still have it somewhere. Together with their OCZ memory voltage module.
Uk can rock 3,250 watt psu from any plug. Then 6,500watt from a faceplate (all uk homes use 32amp ring mains) (2x.2.5mm T and E)
I just had a dark power pro 12 1200W literally blow up, I bought mine new and I had only used it for a year and a half. It ended up taking my power strip with it but fortunately nothing else. Since this is the first time I've ever had a PSU die me it's going to be hard for me to trust the longevity of Be Quiet's PSUs moving forward. That's not to say the PSU was bad while it was working though, it was always silent and did a good job feeding my 12700K + 3080ti system. Also whatever built in protections definitely did their job and prevented the PSU from taking anything inside my computer with it.
So far the RMA process has been fairly smooth, but we'll see if I'm even able to get a replacement since I've seen mixed feedback about Be Quiet's RMA support. Anyways, just wanted to share my experience. Might update if I get a replacement.
Wonder did Rossmann overclock his "ring".
I overclocked my ring and went back in time....
Seasonic TX-1600 or Seasonic PX-1600 can beat this on actual testing, on various testing categories including noise.
Agree. But those are more expensive as well 😉
EU plug can go to 2400W if it's wired for 10A or 3840W with 16A so in europe you could consider up to like +3KW PSUs
The click is just bypass relay for the termistor to limit charge current of the input caps and the switch is probably run at like 5v I would imagine nothing fancy just signaling to PSU that's it should pull the trigger for big power
The DPP 11 and 12 also have that panel / switch.
Many power supplies are most efficient when loaded to about 70% or so. So if you buy a 1200W PSU and your system only pulls 450W, it will (possibly) run less efficiently and cost you more on your power bill. Some manufacturers provide a load vs efficiency curve that you can consult.
Probably why my energy bills are so insane 😂
I have a 3080, 7800X3D with a Corsair HX1200
A ton of RGB though and about 12 different peripherals including joysticks and pedals
I checked to see if anyone mentioned this. Replying to help be more visible. It is not the same concept of future proofing as other components.
False! Most PSUs are very efficient from 20% to 95% load and even at 10% load they still have +90% efficiency! Stop spreading fake news.
Just ordered the Dark Power 13 1000w for $180 on cyber monday; seemed like a pretty sweet deal and I'm excited to build with it!
I recommend a sound test before installing it. bequiet has been plagued with very loud PSU fans.
@@cl4ster17ironic
@@cl4ster17 ironic XD
@@cl4ster17 what a scam lol
Our breakers are typically 16 A, so theoretically we could go up to 3.6 kW PSUs. Of course, that's assuming an impossible 100% efficient PSU. And a reserved circuit for just that outlet.
The galax hof uses 2 12vwhpr cables I doubt you would need 2 separate cables from the psu side but hey this psu can do it if needed , that’s pretty cool
Gotta be ready for a next gen Titan : )
I have the dark power pro 12 1000W in my Fractal Torrent case and that is pretty sweet. The thing is very quiet.

"Must´ve gotten a little excited" 🤣🤣🤣🤣
i went seasonic again. havent heard a thing from my old or new psu. the rail toggle is neat but really should just be a switch on the psu like fan control toggles are.
Shot and sweet review. Love it, thanks Jayjay and team
parts are on the way for my first semi-custom build. The amount of things to be aware of is staggering.
in the eu (220-240v) one outlet is (usually) backed up with a 16amp breaker which gives 3680W
thats one high quality psu if theyre doing what cable mods is known for having nice quality psu cables
I find it redicilous strong power supply, but there is of course a demand for this. The new Threatripper and a 4090 with 600W bios and there you are.
If everything in my system drew max wattage, I calculsted 570 watts. I could have put in a 650, but I prefer to over power every build in case I add or upgrade something. So, I put an 850 in. Future proof 😀
The connector for that PSU was originally used in the Powermac G5. ❤
