Possible problems with my corsair tx-950

post #1 of 14
Thread Starter 
Hi. I have had this power supply for about a year. It powers my sig rig. About 4 months ago one night the computer shut down and rebooted with the message asus has detected power surges in the power supply and shut down to prevent damage. So I reset my overclocks back to stock and have been running that way ever since. Well last night same thing happened while playing a game. And it also happened tonight while playing the same game.

Is it likely there is actually a problem with the psu? Or do you think it may be a glitch in the motherboard? It only happens while gaming. Im wondering if its safe to disable that saftey feature in bios, or if it is actually preventing damage because my psu may be going. btw, got this psu brand new in the box. Has a 5 year warranty, so I can rma if need be. Thanks in advance for any advice/ help


edit: forgot to mention, i havent updated my sig rig in a while, i no longer have sli 570s but, a single gtx 680. And no longer have the tx=750,

Run some stress tests to see if you can force a shutdown. Use Prime95 to stress your CPU and FurMark for your GPUs.
If there is an issue with your PSU then this should let you know thumb.gif

Some people have said this problem disappeared after the BIOS was updated, indicating the surge protection feature can be too sensitive. The best way to check the PSU is by monitoring its outputs with a digital multimeter, and even cheap digital meters are very accurate (analog ones are not, unless much more expensive). See that the voltages stay within 5% of nominal values and don't vary by more than about 3% from lightest load to heaviest load.

Ok so i ran p95 blend on 6 threads, and ran msi kombuster. Had to use 6 threads in order to get full gpu and cpu usage for some reason. Anyway, after about 2 hours it rebooted giving me the same message about power surges.

I think before I rip my machine apart and rma the unit, im going to what larymoencurly suggested. Any advice on how to do this would be appreciated.

also, when Im in my bios, under monitoring tab, all the voltages look good except my 3.3v . It was reading 2.8 in red numbers. That seems way to low

Never trust software readings when it comes to power supplies.

Your AI is telling you there was a power surge because the PC rebooted unexpectedly.

Go into your device manager, advanced system settings, startup and recovery and uncheck that box that says "Automatically Restart".

Run your tests again.

I bet this time around, you get a BSOD instead of a reboot. And if you wait for the memory dump or hit the reset button on the chassis, you won't get that "power surge" error message.

Ok so I didnt have it unchecked. I did so just now. going to play some diablo 3 and see what happens. Usually itll reboot in the first 15 mins of playing.

edit: rebooted as soon as i opened the game. No bsod, but I did get the same message. Atleast now I can confirm it is indeed the motherboard that is shutting the computer off, and not a software problem.

Now I need to check the psu with a voltmeter. im going to research on how to do this, and give it a go. ill report back with results.

I dont want to sound like a dumby, but when I test my psu with the multimeter it needs to be turned on right? Doing stuff like this makes me very nervous, one wrong move with a probe and i could fry something.

Ok so i tested the psu with a dmm, and everything checks out. my only concern is that there was no load on the psu during testing.
