GTX 570 spiking over 1000W

[cheeseborger]

Hey all, i just built a new system and have found that while playing Rift and Wow it will shut off randomly as if i ere to unplug it.

I did some tests with occt and a few temp monitors mostly hwinfo32, all test showed that the temps were fine in game and during occt tests.

I was not too sure what else it could be so i checked the watt usage of my gpu while testing with hwinfo, it showed that it wa average round 40W-100W usage but then i noticed it was spiking over 1000W and after leaving occt on its PSU test for 10 minutes my pc shut off.

My question is wether or not this is a PSU issue or a graphics card issue? on nvidias site it says minimum 550W PSU.

I am using an i5 2500k oc'd with asus p8p67 pro mobo to a modest oc of 4.3ghz, a msi gtx 570 not oc'd, a mushkin 1000W PSU
and other goodies that arent too important.

It should also be noted that the shutdowns are completely random sometimes 5 minute into game and other times 3 hours in, and guaranteed it is not overheating.

I would suspect the PSU first!

Yep, seems like the PSU could be up to no good!

Got a 1000W PSU powering 3 overclocked GTX570's and a heavily overclocked Core i7 960... I would say your PSU is faulty

kk, thanks for the replies. think i should return for refund and go with a different brand or just get the part replaced?

Also, would the anted truepower new 750W be a good choice?

Yes it is a good PSU http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story4&reid=140

Thanks, rolli.
I was looking at my psu and noticed it has a switch for combined/split rails so i switched it to combined and am still noticing high wattage spikes with hwinfo32 but i cannot replicate the shutdowns now after testing for 15 mins on power supply test with occt.

 

[Rustyy117]

Where does hwinfo32 show power consumption? I can't see it anywhere : /

 

[cheeseborger]

If you load it up with sensors only checked it shows all ur temps fan speeds and voltage/wattage

Thanks for the info!

However the program is obviously not accuratem its saying that one of mt GPU's hit 3634C... if that was the case it would be a pile of dust...

It also reported one GPU using 71W under load and another using over 1000W and 1023V... the fuse in the wall socket would have burst into flames

Buy a $20 wall socket power meter (Kill-a-watt) if you want to get actual system power draw.

haha, kk so ill ignore that, but like i said the problem seems to have gone away completely, however i did revert back to stock clocks and change my psu from split to combined. do you think i should still return the psu for another or could it have just been that having a 31% oc might have caused a random shutdown under full load?

Can very well have been.

 

[cheeseborger]

Hmm well, i guess ill give it another few days and if it happens again i'll know its the psu
