Power supply was completely dead. This has been the most frustrating build I've done in over 25 years!!! It has been making me crazy and I'm working on it in my garage in the summer, which is just making it even more difficult. lol!!
my pc keeps shutting down after 3 hours and I want to check my psu with multimeter but I can only found tutorial with colored cables of psu out there. Just wanna say thanks bc ur video guide me to test almost every pins. thank you so much!
Thanks for this, but I did hear that you can still have a failed power supply despite it showing good voltages on all the rails, because sometimes it will be fine with no load, but when you load any of the rails, it will fail. Do you know a good/easy way of adding load to the rails whilst testing? Thanks.
Amazing, I have one of those Amazon testers, but did not understand why it was beeping. I'm going to try with the PCIe cables and see if I can get stable readings. WIth just the big Motherboard cable connected, it does a 'LL' on one of the 12v- rails and shows slightly miss-matched 12v readings.
helpful i have a hyte 60 and the front panel wont do anything but running the jumper test and the power supply came to life i will have to email hyte and get some help on this issue
Hello, I am an experienced IT professional. Prior to that I ran a PC repair shop from the late 70's and into the early 90's. I am also well versed in networks and servers, The issue you have experienced is due to the fact that the so-called "jumper wire" test, as illustrated here, is quite meaningless. Your result where the power supply seems to "come to life" when turned on with a jumper wire, but failed when installed in the PC is evidence of the uselessness of this test, See, the jumper wire test as shown here is a no-load test. That means that the power supply is being tested without any load being place on it. But, when installed in the PC, and placed under load, your PSU fails. Perhaps, you've seen this kind of this before -- a car battery can't start a car, but may still light the car's interior lights. So the battery is fine when used with a minimal load from a few lights, but cannot handle the stress of the load required to actually start the car. Basically, the jumper wire test is merely showing that DC voltage is being produced by the power supply. Problem is that you don't know how much amperage is behind that voltage. So, when placed under the stress of the PC's high demand, it may fail. The multimeter test as demonstrated is interesting, but also completely meaningless since the readings are being taken on a PSU without any load being placed on it. While you may well read 12v, 5v and 3.3 volts at various positions on the connector, you cannot determine if the PSU can supply those voltages at it's rated wattage. As for the power supply tester in the video, I checked out it's Amazon listing. Personally I wouldn't use it. If you are going to test a PSU, use a quality PSU tester such as the Thermaltake Dr. Power series testers. I have a Antec tester that is quite simple but effective that uses a couple of wire wound resistors to provide a load for testing. Unfortunately Antec no longer makes this tester. In a pinch, just leave the PSU you are testing installed in the PC, disconnect the 20/24 pin main connector, but leave the PSC connected to everything else, such as the the graphics card, hard/SSD drives, case fans, etc. Now, install the jumper wire on the 20/2 pin connector to turn on the PSU and use a multimeter as shown in the video to check the various voltages from the PSU. The graphics card, hard/SSD drives, case fans, etc, should provide a sufficient load to actually test the PSU. Good luck!
Very helpful. My daughter is trying to build her first PC but the PC didn't show anything on the screen and no LEDs on the motherboard. The power button works and the fans come on, even the CPU fan works. I checked the CPU 8 pin connecter and measured 8.8V dc but unstable. I have returned the PSU assuming this is a fault. From your video it seesm that my diagnosis was correct. There are 8 pins but I found that only 6 are used for power, 3 positive and 3 GND. What are the other two for?
Thank you turns out my evga b5 was running just fine, it just missing a cables on 24pins so my PC couldn't run. Im buying a cable online instead of paying 40$ to ship to EVGA to warranty.
My younger brother's PC stuff came today. We both have no experience in this, but I'm better at building and following instructions. The instructions said to test the power supply first. I used the jumper that came with it. I plugged it into a surge protector, like it recommended and turned it on. The fan barely twitched for a split second within turning it on, and the light in the house dimmed for a split second from turning on the button. Then about 1-2 seconds after turning it off, the fan does a slight rotation.. I'm not sure why it's reacting this way. It's odd. I noticed that the jumper blocks inside the connector are at different positions to the instructions booklet that shows how to use a jumper wire. So I tried using a jumper wire in the ports that the instruction booklet showed. But the results were the exact same. 🤦🏽 Hope I didn't ruin it by following the instructions.. Only other thing I can figure out is that maybe the surge protector that I plugged it into didn't feed it enough wattage? I would've tried plugging straight into the wall, but was afraid of destroying it, if I haven't already.
If you follow the methods in the video, then you only test it until you check all cables and make sure you are getting the correct readings. If you are stress testing, then there isn’t really a timeframe. Run a few benchmarks and you should be good to go.
You should meassure the PSU with at least some load. I like to connect a couple of old hard drives there. Without load it might look ok, but it may not be.
@@TechRated For most new PSUs the fan doesn't spin when using jumper wire they need a load on them I use a case fan plugged in a Molex connector to test it.
Thank you for the pinout on the power supply plug. Mine just went out last night. Checked the power and reset buttons and they both checked out. Checked the power cable itself and it checked out. Pulled power supply from the case and nothing. It is completely dead.
I have a Corsair RM750 power supply, and sometimes my PC resets suddenly. I've measured the values of the power supply, and everything seems fine, but when I turn on the power supply, the fans stop again after 10 seconds. Is this an issue?
What if I don't have a cable like that. Can I put a jumper on the correct pins on the board. Mine is a streamer and I don't have a cord like that. It's just a motherboard with a pico PS and some other stuff. Not powering up
so if i understand this correctly.. the 24pin connector layout is somewhat standardised??? all wires should lead to corresponding connectors, right? But how come when you try and shop for custom cables, you have to look for which manufacturers psu you have? Like ive been told some use different cable layout for example.. Should i watch out when buying for a psu tester or should it be standardised for all psu.s? Also us vs eu voltage? Does this mean id have to exclusively shop in europe for a european psu?? Im okay.ish with building pc by myself, i just never delved into voltages and amperages - fine electronics basicaly.. one is lack of equipment, the other is fear of breaking something expensive with like primitive tools XD
Hello sir , just want asking when every time jumper the fan just spin less then second , then spin off its that not normal but pc working fine just brought second psu 850w gold, tested in 550w bronze its just like video fan running fine, thanks
All I see in mine is that when oowered on either connected to the mobo or with the wire short circuit as shown that the fan of the PSU tries to spin but stops, and I can hear a light buzz on it as if there is current in there, but nothing starts. If ut is connected to the mobo then there is a split second start where the fans of the PC turn fir that splitbsecind and then stops... should I remove the PSU fan and try from there? or the pin (of the PSU fan ) should be connected to di this ? Correction, when not connected the Mobo and short circuit as in video with the 2 pins there is 12v to the Gpu cable, but fan not spinning. With ir without the fan connected to the PSU there is a buzz heard in the Power supply, Now when connected to the Mobo there is no light to the mobo and dies not start, as described...Will get ut to service but what can be your verdict ?
My pc shuts down, tried all these methods and the psu is all good. Tried every single socket on the 24pin aswell. My gpu failing? Appeared black small squares all on my monitor yesterday. Help please!
my pc would turn on but it wouldn't turn on my monitor and I've updated my drivers and checked the wiring could it be my power supply not providing enough? I have a 750W gold ASUS TUF PSU, a 4070 GIGABYTE RTX, and Ryzen 7 7700 8-Core Processer. Should I check it like this?
I took my Be Quiet Dark Power Pro into my local computer shop and the guy tested it with his power supply tester and it showed all the correct voltages and told me that it was OK. Yet it fails the paper clip test (I used a strand of solid copper wire from a ground cable for house). The fan will spin for 5 seconds sometimes, but for the most part, not at all. How can it pass the voltage test at the computer store and fail the paper clip test ? I though the voltage tester at the store was the end-all test ? To me it sounds like there is a failing relay in the PSU, I can hear it click on, and when it does, the fan spins, but very often it just clicks off then on to where the fan barely comes on, or not at all. At this point the power supply tester seems more like a gimmick then something that should be reliable.
Thank you so much. I had bought components for a build over time so its not built yet and I was stressing that too much time has passed w/o my building the pc rig and so if the PSU is DOA I'd just lose my money. Watched one video but my PSU is modular and all the wires are black so I have no avail to the color coded wires. 🤣 Then there was your video a newer PSU and I learned . I'm now collecting parts for a different i5 12600K none gaming rig that needs more Watts. Can you tell me which of the following is a better 850W PSU CORSAIR RM 850W vs. Thermaltake Toughpower GF1 850W? Unless you can recommend something better in the same price range? Should I go single rail or multi rail? I want to run a virtual box to install & production software. I don't earn money doing that so I can't spend tons of $ on such a production rig, I'm mostly learning for fun. Again thank you for sharing your knowledge👍
Both of those brands will work. I usually go with Corsair or EVGA for my power supplies. In the past, I have used Thermaltake and it did quite well. Most PSUs these days are reliable and do what they are supposed to do. However, the price is determined by the power output, features and efficiency. As far as features go, I am talking about if it is modular or not, RGB, display, etc. Efficiency is the rating (Ex: White, Gold, Platinum, etc.). But I would go with whatever your budeget allows. The ones you mentioned are very good choices.
Good day hoping for answer im from Philippines i buy a silverstone 700w power suppply and it needs 230v output but we only have 220v here how can i use my psu. Thanks ifol
Any way to test an HP L 8261-004? It has 2, 4pin connectors and 1, 3pin connector. No tutorials found on youtube or anywhere. When I push start the fan doesn't run so I guess it is bad. Would be nice to test.
I had the same issues as well but the difference is the monitor shut downs and my keyboard lights turn off also. Sometimes it restart by itself sometimes not and i need to force it to boot or turn it on again by turning the whole pc off. But the thing is. My pc still running all fans and lights are running and on including the cpu fan but why only the monitor and keyboard loss signal or lights? Even in idle or UA-cam still random crash or shutdown. Can anyone help me address what's the problem of my pc??
If your power supply fails to turn on. The first thing to do is remove your video card. Then do a power on test. If it still fails remove any card in your sys and retest. Also remove all memory clean contacts on mem. and all cards. Retest. Then test your PS.
So I am getting a fluctuating volt of between 11.99v and 12.00v on 2 of the 12v connection on the pcie 8pin connector, is this okay? Using a multimeter
Awesome info thanks!! but question would this be a PSU issue? my computer turns on all RGB works fans on GPU are not spinning and only one monitor works? all these issues just happened out of nowhere thanks!
I know it's been 5 months. But fans on gou not spinning can be normal at startup. But if they aren't spinning while the GPU is under load (in a game). Then that's a problem. But overall. Could it be a PSU issue. Maybe. Sounds more like a mb (maybe some cables aren't plugged in) or software thing. But also I'm not an expert. Hope you don't need this info anymore lol
Would like to see info on testing the modular cable outputs directly, rather than through the cable. The PSU end is not standardized, so we cannot expect (for example) the top-right pin to be ground on the PSU side. If you're making custom cables and want to take a pinout before you start, this isn't really useful.
@@askell3738 Ultimately, i plugged the cables in and traced the individual wires back to the psu. Did this for each wire in the cable to get a presumptive pinout, then used a multimeter to verify the voltages.
how are your TechRated, i have a 3070 with ryzen 7 3700x 32ram from t force, and SSD, so the thing is like 6 months ago my computer when I turned on, start but no display on monitor, and check the rams, GPU stress test, clean everything make sure all is plugged, and damn I do everything, but still the same thing, is not all the time, I turn the PC on 3 times with no problems but when I do it for 4 time, the PC turn on but no display , so I'm really don't know hats going on, I'm suspecting on the psu or last thing GPU but is weird because I don't have shutdowns or green lines or freeze my PC runs excellent is just sometimes start but no display, can you help me please?, i can pay if you want! but please man idnk what to do! and sorry my grammar i don't speak English ):
If the PC turns on, then it probably isn’t your PSU. It sounds like you may need to do some Windows updates and maybe GPU driver updates. Not sure. Not having an output to your display randomly is strange. I would do all updates first and then go from there.
You might also need to update your chipset. Other than that, check simple things like cable connections and monitor settings. I guess it is possible that you might be having issues with wattage to your GPU if your PSU isn’t able to output what it needs. What GPU do you have? How many watts is your PSU?
@@TechRated thank you again and i did the chipset update the bios update like 2 hours ago, and I have an RTX Gigabyte 3070 OC 8gb and a 750w power supply of a weird brand. o., bro I will pay you this wednday like 10 dollars just for answer me

My pc still running all fans and lights are running and on including the cpu fan but why only the monitor and keyboard loss signal or lights?
Even in idle or UA-cam still random crash or shutdown.
Can anyone help me address what's the problem of my pc??
hi guy! what is the PG number?
That is the power signal. Normal values will be 100-500ms.
mine turns on but after like 2 seconds it shuts down
If your power supply fails to turn on. The first thing to do is remove your video card. Then do a power on test. If it still fails remove any card in your sys and retest. Also remove all memory clean contacts on mem. and all cards. Retest. Then test your PS.
It is same all psu?
So I am getting a fluctuating volt of between 11.99v and 12.00v on 2 of the 12v connection on the pcie 8pin connector, is this okay? Using a multimeter
That is basically 12v so it should be fine.
Awesome info thanks!! but question would this be a PSU issue? my computer turns on all RGB works fans on GPU are not spinning and only one monitor works? all these issues just happened out of nowhere thanks!
I know it's been 5 months. But fans on gou not spinning can be normal at startup. But if they aren't spinning while the GPU is under load (in a game). Then that's a problem. But overall. Could it be a PSU issue. Maybe. Sounds more like a mb (maybe some cables aren't plugged in) or software thing. But also I'm not an expert. Hope you don't need this info anymore lol
What if you get something like 12.120V on Hardware Monitor? Is that fine? I'm using an MSI MPG A750GF 750W 80 Plus Gold Modular
my power supply fan run for about 2-4 seconds then it stopped. Is that normal? it’s a new one I just brought, it is unlikely broken.
It's the motherboard
Would like to see info on testing the modular cable outputs directly, rather than through the cable. The PSU end is not standardized, so we cannot expect (for example) the top-right pin to be ground on the PSU side. If you're making custom cables and want to take a pinout before you start, this isn't really useful.
Do you find a way to find the ground on the psu yet? I'm having the same problem right now.
@@askell3738 Ultimately, i plugged the cables in and traced the individual wires back to the psu. Did this for each wire in the cable to get a presumptive pinout, then used a multimeter to verify the voltages.
Hi when I plug my power supply in it trips the curcuit breaker in the house,any suggestions on how to test it for short
Make sure that circuit it's overloaded do plug in to many things.
My power supply does not have a switch
My psu fans are turning on no matter whether the switch is turned on or off
Expected little bit deeper
how are your TechRated, i have a 3070 with ryzen 7 3700x 32ram from t force, and SSD, so the thing is like 6 months ago my computer when I turned on, start but no display on monitor, and check the rams, GPU stress test, clean everything make sure all is plugged, and damn I do everything, but still the same thing, is not all the time, I turn the PC on 3 times with no problems but when I do it for 4 time, the PC turn on but no display , so I'm really don't know hats going on, I'm suspecting on the psu or last thing GPU but is weird because I don't have shutdowns or green lines or freeze my PC runs excellent is just sometimes start but no display, can you help me please?, i can pay if you want! but please man idnk what to do! and sorry my grammar i don't speak English ):
If the PC turns on, then it probably isn’t your PSU. It sounds like you may need to do some Windows updates and maybe GPU driver updates. Not sure. Not having an output to your display randomly is strange. I would do all updates first and then go from there.
@@TechRated thanks bro, yeah i gpu drivers are up to date, same my windows, today I will update the bios, and keep testing o.O
You might also need to update your chipset. Other than that, check simple things like cable connections and monitor settings. I guess it is possible that you might be having issues with wattage to your GPU if your PSU isn’t able to output what it needs. What GPU do you have? How many watts is your PSU?
@@TechRated thank you again and i did the chipset update the bios update like 2 hours ago, and I have an RTX Gigabyte 3070 OC 8gb and a 750w power supply of a weird brand. o., bro I will pay you this wednday like 10 dollars just for answer me
@@tcpilot6995 No worries! This is the goal of my channel! Hopefully your PC issues get worked out. I appreciate the support! 👊🏼
wow i use a jumper to test my psu and now it broken

Want to cooperate with you about promoting PC software. Thanks
This is almost useless. How about testing voltages and psu temps under load? A 300 watt chinesium psu will pass these tests in the video.
Please, tell us how to test a psu under load.
this video is useless when some people need to check the power supply under load
You are useless
Please, tell us how to test a psu under load.
useless info

That's Mr. Nerd to you!
My psu keeps making a clicking noise when I plug in the Jumper bridge. Is the psu bad???
