I appreciate your in depth review of the new contour but it still has major flaws with the connector design, it shouldn’t wiggle, that is what’s I feel is causing the issue along with the incorrect plug-in and still needs a wider clip to prevent wiggle while threading the wiring basically it’s too loose to the header if it was wider and the 12-by 6 cable should be two tone to easily spot incorrect installation, until these changes are mandatory I won’t have any faith in the new pci standard
The wiggle won't be a problem with the new standard because it has an state for 0 power and mechanical separation of the sense pins if they come loose, along with the cable being much cooler under load. I think all of this would be sufficient to make the problem start if not start a new problem when peoples GPU aren't working because there is no power since the plug is coming out. Also they don't make any cable more than 1 color for looks. You are can also use a multimeter to check each pin in a few seconds to see if it's wired correctly.
I now use the Seasonic 90° cable after remove the 180° CableMod adapter. I didn't have any issues with v1.0 or v1.1 of thr CableMod adapters but now they said we have to remove them because it's unsafe! Ok, i did it and hope I'm now safe with the Seasonic 90° cable for ever or as long I keep the 4090! Happy new year 🎉
Not an easy video to comprehend for the average person. Nevertheless it is a technical subject and as such you need to know your stuff to get it. Very informative and in detail information about perhaps the hottest subject in graphics cards and PSUs.
Is it better to use 12vhdpwr straight from psu to gpu, or to adapt from 4x8 pin pcie to 12vhdpwr? I would ensure ideal connector seating position in either scenario.
@@MansoorAhmed-ts3eg look up a picture of H+ and H++ plugs so you know where to look for the lettering. But you want one that was made late 2023 if you can buy new.

Hello! I'm currently assembling a computer build that includes two NVIDIA RTX 4090 graphics cards. I've acquired nearly all the necessary components, but I haven't yet purchased the power supply unit. I'm considering the Corsair AX1600i. Do you think it's a suitable choice for this setup? Thanks for your advice!
The AX1600i is still one of the best PSUs in terms of pure performance, but it is now ATX v3.x ready, so I would suggest you get a new PSU with 12+4 pin connectors, ideally a couple of them to support your 4090s. Look at the Seasonic Prime TX and PX 1600W models.
There were images on reddit at this point floating around a couple months ago asking if they had the revised connector on their graphics card side. Is this the 2x6 one, or was this a slightly revised 12VHPWR in the interim? I have purchased a 4090 that arrived about 2 weeks ago, is it likely i have the 2x6?
Thanks for the vids. I don't understand the high conductivity terminals from the last video. They definitely looked different and looked like they are for the cables termination. But, I can't find any info about them. Are they the terminals for the sense pins?
If you don't use it... The answer is you are not going to have the protection the new PCB of the connector provide with older 12VHPWR versions. It is a damn mess and I would simply recommend you to buy an AMD GPU.
Capitalist reasons purely. Psu companies likely complained that they're questionable quality psus wouldn't meet the standard and thus couldn't get the certification and be advertised with it.
So if I have this right, 12vhpwr/12v-2x6 2x8 pin is safe, assuming GPU power socket is updated to H++? And 12vhpwr/12v-2x6 12vhpwr/12v-2x6 is safe if the GPU power socket is updated to H++ AND the PSU is 3.1 and NOT 3.0?
question I was looking at techpowerup and it says that recommended psu for 4070 super is 550w I have corsair cx550 w psu and it has 1x cable pcie (6+2pin) dual. Would it be ok to use for several days like that.
well those early adopters defending nvidia, claiming "user error" seems to be the greateast beta tester, hopefully the new connector have more margin of error than the old one, personally i think OEM should stick what its working the old 8pin standard its just more safe and unless every card pull the same power as the 4090, there are no reason to use this kind of thing on lower end cards.
Great video. I still think that the new connector is a stupid idea. It seems like they created something new just to be able to say that they created something new.
I'm confused cause my english isn't that good. I'm building a new system right now. I ordered yesterday a Thermaltake Thoughpower GF3 750W. Should i return it to be futureproof? Should i avoid Nvidia GPUs? Is there a chance that the PSU manufacturers will bring a let's say rev.b model and you can swap them? I need a PSU right now what to do?
@@HardwareBusters HA! Yes 3.1! I want to invest in a high quality 3.1 PSU and be set for the next few years. I’m looking forward to your reviews on the ATX 3.1s when they are released. Keep up the good work!
@@thedarkangelpt 3.1 PSUs are the new ones that will come to market sometime in 2024. The PSU will have the new connector as well. Simply put your 3.0 PSU is already out dated and doesn’t have the enhanced protections.
i think the whole standard would have been 100x better if they ahd made the plgu and socket parts bigger. like this thing should have been the size of two PCi-e power plugs side by side. or atleast the size of one and a half PCI-e power plugs. had they designed the plug and socket biger , i don't think there woudl ahve ever been one single melted 4090.
I really need to upgrade my current PSU, it's a Coolermaster 650w 80+ Bronze Masterwatt TUF edition, since I'm using an Asus TUF 4070 (Non Ti) with an 8pin on it, yes the Asus TUF 4070 OC has an 8pin on it. Do you think my 650w can handle the 4070 and Ryzen 5 5600X?
Canada is requesting a class action suit with punitive at this point if this keeps up for anybody who has a receipt of a 4090. And the lawyer that has balls. My eyes it’s a slam dunk. Nvidia should take full responsibility on a major recall or at least send me back 50% of the value of this card because it doesn’t matter what I do every 20 minutes. I’m feeling the connecter and depending on what I’m doing I have to back off.
Still dont get the point of all that 12vhpwr and now the 12v2x6 bs. I do not see any real world issue that connector solves, imho the good old 8 pin is enough for everything and works reliable. If a gpu rally needs more than 450w (3x 8 pin) we have other issues than the 8 pin connector only delivering 150w, the issue is tat the gpus really need wayy too much power!
unfortunately. didnt find the explanation i was looking for. Technical explanation is okay i guess, but its so not oriented to people going through this for the first time. I got confused more after watching then before. given that HWB kinda outgrown psucultist list in terms of psu's market coverage, its little sad that this area remains so poorly covered for newbies.

So glad I waited to buy the 4090 later as I got the H++ (12v-2x6) connector I got lucky I feel,
I am also in market for 4090, how do we know which connector it has? Or it's just luck?

So, if I buy a 3.0 psu now, I'm missing on the lengthened new pins.
If I wait for 3.1, I'll be missing on longer hold-up time.
What to choose?
ATX v3.1 with 17ms hold-up time and above :)
@@HardwareBusters Any PSU's like that in 2024?
these videos are so informative
great clarification, thanks!

you can check it on your own. If the sense pins are close to the socket's edge, it is 12VHPWR. If the sense pins are inside the socket, it is 2x6
Can you share any close up photo of them uu@@HardwareBusters
Ari has spoken….. I’m doomed!
Thanks for the vids. I don't understand the high conductivity terminals from the last video. They definitely looked different and looked like they are for the cables termination. But, I can't find any info about them. Are they the terminals for the sense pins?
Great, thank you !!!
Great video!
Nvidia should bite the bullet and revert to 8 pins connectors.
After watching this 3 times to try and understand the details, is it safe to still buy a PSU that has native connector on it ?
If you don't use it...
The answer is you are not going to have the protection the new PCB of the connector provide with older 12VHPWR versions. It is a damn mess and I would simply recommend you to buy an AMD GPU.
Why would they shorten hold-up time?
Capitalist reasons purely. Psu companies likely complained that they're questionable quality psus wouldn't meet the standard and thus couldn't get the certification and be advertised with it.
So if I have this right, 12vhpwr/12v-2x6 2x8 pin is safe, assuming GPU power socket is updated to H++?
And 12vhpwr/12v-2x6 12vhpwr/12v-2x6 is safe if the GPU power socket is updated to H++ AND the PSU is 3.1 and NOT 3.0?
any ATX v3.0 PSU with 2x 8pin is ATX v3.1 automatically. The important thing is for the GPU's header to be H++ in any case.
What did he say at 3:29 as I can not understand what he said and I feel it's important.
Ahh, I can't figure it out either. I 'think' "version". "atx version 3 psus"
@@OmahaGTP it was atx 3.1 is what he said
so is it safer to use the 12VHPWR connector only on GPU side and not on PSU side ? I think there are cables with 2x 8pins on PSU side available?
Both connector types are safe if they are correctly used/installed.
omg, can anyone tell me the name of the devices used in this short clip 2:08 , the white color box, the pcbs, etc. I want to purchase those items.
question
I was looking at techpowerup and it says that recommended psu for 4070 super is 550w I have corsair cx550 w psu and it has 1x cable pcie (6+2pin) dual. Would it be ok to use for several days like that.
you don't mention the CPU. The CPU is also power-hungry. I wouldn't use this PSU for the 4070, even with a low-power CPU.
Which one should i buy? The MSI MPG A850G or the new MSI MAG A850GL? Please help i dont know about PSUs :(
Get a Corsair RM850x Shift if the side panel is ok. From these MSI PSUs, I need to review them first to provide advice, sorry.
So is the Super Flower 1000w Leadex VII I just ordered compliant with the 3.1 spec? It sounds like it is but I just want to clarify.
Yes, since it has a 2x 8pin.

i want to build a new PC with 4090. could you give some short tips on what brands exactly i need to look at to get this done correctly? thanks.
Choose a PSU that already has a 12+4 pin connector, and with 1000W at leasty capacity.
@HardwareBusters thank you. I look at the msi meg ai1300p which has such a connector. Am i looking at a right type of psu?
Hi. is 11.904 on +12v dangerous or defective? I bought a new psu PQ750M Deepcool and on HW monitor is showing 11.904.
BIOS sensor volt readings are inaccurate in most cases, so don't pay any attention to them.
I'm confused cause my english isn't that good. I'm building a new system right now. I ordered yesterday a Thermaltake Thoughpower GF3 750W.
Should i return it to be futureproof?
Should i avoid Nvidia GPUs?
Is there a chance that the PSU manufacturers will bring a let's say rev.b model and you can swap them?

This PSU is fine, for mid-end GPUs.
