i got a new one, a corsaire 650 which will replace the 450w one
but i would like to make some kind of stress test on them, with gpu+cpu
what is the best software to monitor the use of my psu ?

I feel that my psu is failing and i want to check it. Thanks!
You could try monitoring your voltages with https://www.hwinfo.com/

Like the 12V voltage should be probably like from 11.5V to 12.2V or something like that, mine seems to drop to 11.7V under load.
And same with 5V voltage, don't wanna drop it too much...and same also with the 3.3V voltage.
What makes you think it's failing? Getting random shutdowns?
You can get a PSU tester off of Amazon fairly cheap and test the different rails like so: https://www.lifewire.com/test-a-power-supply-using-a-power-supply-tester-2626160
I suspect my psu is dying on me because my pc restart (Kernel-Power Critical Error, unexpected shutdown) under heavy load (gaming and OCCT PSU test) but the voltages both the BIOS and Speccy (or HWMonitor or OCCT) display, while gaming or running a test, seems fine:
AVCC & 3VCC = 3.376V
VCCIN = 1.744
DRAM goes from 1.488 to 1.504
5V = 5.140V
12V = 12.120
How can i really check if it is my psu and not something else? I don't have a spare one to try, i could buy from amazon and return that if needed but i would prefer to avoid this.
Thank you for reading this :)

Hey, im looking for a pice of software (preferabel FOSS, but free is enough) that is capable of stresssing CPU and GPU Simultaneously so i can measure something close to the peak/maximum power draw at the PSU. I consider the power consumtion of the nvme disk, usb-devices etc. insignificant. Im to lazy to use a linux bootstick for this, is there some Windows based software you could recomend?
We use the cheap coolmax PSU testers, and have to replace them all at least once a year.
Is there anything out there that is higher quality but still portable?
What do you use to test Power supplies?
Hi All,
Since I built my new pc, sometimed I get random reboots (kernel power error 41). I checked everything and my conclusion is that my PSU could be faulty. I would like to monitor the voltage rails over time (12,5, 3.5 volts) and get a report, so I can check if there are any fluctuations in the voltage. Can RGB leds cause such issue?

I have a 750watt XFX power supply and I added a Kraken G10 and Corsair H50 to water cool my GPU. Is there a program I can run to make sure my PSU isn't being overloaded or pushing its limit?
Thanks everyone for the help!
I recall seeing software that would measure youre power supply outputs over time, but can't seem to find it. Anyone know what I'm talking about?
I have a Corsair 750xm power supply that's been running since mid 2015. I've been wondering how much life this thing has left given its age. I'm not experiencing any issues. Just wondering if there's some software to check its health so I know when I should probably replace it.
I have a 450W Corsair CX450M and I'd like to see if all my stuff overloads the PSU
I was troubleshooting a malfunctioning computer for a family member and I think the PSU might have gone bad. It's a reliable brand though (not relevant to this question) so I was kinda suspicious if that really was the culprit. I would like to the test the PSU before telling them to buy a new one, but I don't want to test it on another working computer and possibly fry it, and I don't want to do that paper-clip thing because it terrifies me. I'm not quite sure how to properly use a multi-meter on a PSU either and was hoping there's just a 100% idiot-proof device out there where I can just plug it into the PSU ports and let it tell me if the PSU is bad or good.
Does anyone have a recommendation for a specific brand or type or device for this sort of testing?
I have been having spontaneous restarts when doing intensive tasks such as gaming. When isolating certain variables, I have not been able to identify what the issue is. I get error code WHEA_Uncorrectable_error. I have done a ram test and got 0 errors, I have done long GPU stress tests as well as CPU tests. When I run BOTH Prime95 and Furmark at the same time, I can get the PC to repeat the errors. This makes me think it is a PSU problem due to the increase in power consumption. Is there another way for me to test for this without having other hardware to replace and isolate the PSU?

Last night, my computer shut down on me and refused to power on. I checked the outlet and no problems there.
Nothing happens when I hit the button on my PC.
Pretty sure it's the psu buti want to be sure before i sink money replacinga working part.
Best option: Borrow a different one and try it with the loaner.
If that's not feasible, and bearing in mind that I'm not responsible for any shocks, fire, smoke, blown components, dead dogs, terrorist attacks, and general mayhem, you can test the basic functionality of the PSU (turning on) this way:
-
Unplug the computer from the wall socket / mains power. Also unplug your monitor(s), external speakers etc (to avoid discharges through those peripherals.) Wait 30 seconds.
-
Open your system and disconnect any and all components from the power supply. Repeat: Nothing should be plugged into the power supply, disconnect all wires from their respective plugs inside the computer.
-
Get a paper clip, bend it into an U shape. Or a wire, doesn't matter what kind, but it shouldn't be a stranded one.
-
Plug the PSU (and just the PSU) back into the mains power.
-
Look at the 24-pin ATX connector (the one that goes into the motherboard). There will be exactly one green wire, and multiple black ones. If there's more than one green wire, abort (and get a different PSU from a manufacturer that cares about standards, electrical hazards, and about life in general, that sort of thing.) The black wires are connected to ground, the green wire signals the PSU to turn on.
-
We're going to connect the green wire to any one of the black wires. It's quite safe, the current flowing between those wires isn't enough to even stun an ant. (That isn't the case for the others, make sure you pick the right wires; if you're unsure, don't.) Use the paperclip or the wire to connect the corresponding plug receptacles and keep the wire there. The PSU fan should have started to turn and should be keeping it up as long as you keep green and black connected.
If that didn't happen, your PSU is dead. Of course, just because the /PS_ON circuitry is alive and well doesn't mean the rest is too, but it's usually a good indicator.
Edit: Improved, clarifications.
Many motherboards have an LED on them that will light up to indicate power. No LED = dead PSU.
That's not always a complete guarantee though; if you don't have a PSU tester (guessing that's the case) the only other way to be sure is to swap in a known good one. If you have a local PC shop and they're not complete arseheads they might be able to help out - it only takes a few minutes and a spare PSU. Makes sense for them as you're gonna buy a replacement component one way or another.
First up, though, unplug the power, then unplug the PSU connector from the board. go and have a cup of tea, then come back and plug them back in. See if that clears it up - you never know your luck.
Looking to upgrade some tools and am considering Thermaltake's Dr. Power tester. Are their other options that can test under loads?
Read the label to figure out the max amperage for each rail.
Use ohms law to calculate how much resistance you need to achieve close to max amperage.
Short green and black wire of PSU.
Then use a big high wattage resistors that you calculated earlier to apply a load to each rail. Install it between the rail and ground.
Measure voltage and amperage.
I just use a multimeter. The tops of power plugs are designed to fit the lead of a meter into them for testing.
Last weekend a friend of mine brought his computer to me. He was at the end of his rope with his machine and why it wouldn't complete POST. He had replaced the memory, he had replaced the CPU, and was getting ready to order a motherboard, since his was out of warranty.
He would not have done ANY of this, if he had talked to me first. When he brought his machine over, I had asked what he had done, and my first reaction was to say, "sounds like a dead power supply". His response is one that I see a lot in this sub, and it drives me CRAZY:
"It can't be the power supply - I did the paperclip test and it starts up! I know the power supply works!"
After I picked myself up from the mild stroke I had, I went out to my garage, grabbed my tech kit, and grabbed one of my favorite tools: my power supply tester. 10 seconds later, I confirmed what I basically already knew: the 5V rail and the CPU's 12V rail was dead. This despite the power supply running.
A power supply tester is only about $15, folks. It's a tool that, IMO everyone who gets inside their machine should have, even if they don't have a problem. It's like a plunger - better to have BEFORE you need one. If for no other reason than you can check yours or loan it to friends.
The paperclip test means JACK as far as knowing your power supply is functioning. Literally all it proves is that the power supply will startup. But that's like saying a car that is up on blocks can drive to the store because the engine starts up.
Edit: because a lot of folks have brought them up, I'll go ahead and address multimeters. They are absolutely a good substitute if you don't have a power supply tester similar to the one I linked. My only complaint with them is that, I don't know about everyone else here, but I don't have the pin-out diagram of power supply connectors memorized (hell - I still have to lookup a patch cable diagram when I make a CAT6 cable as I have it largely memorized but I want to be 100% certain). So I'd have to follow a diagram and ensure that I'm connecting the proper connector pins in sequence and verify that they are putting out the correct voltages. Then consider that a modern power supply can have upwards of 50 pins or more to test (24-pin ATX, 4-8-pin CPU1, 4-8-pin CPU2, 6/8-pin PCIE1, 6/8-pin PCIE2, etc). I still recommend a tester over a multimeter simply for the sake of speed. If you have the time and patience, however, to do a multimeter test, then you're actually probably better off as this tool definitely would fall under Alton Brown's unitasker rule.
