Hello!
Today I recieved my new ASUS GTX 770 and the Corsair CX600M power supply to go with it for my new PC that I recently purchased earlier this month.
I've installed everything without a problem, but now I'm experiencing a sudden power loss to my PC when running a game, seems perfectly stable when idle or general internet browsing which I'm doing at the moment.

My current specs:
CPU: Intel i5-3570k 3.40ghz
Ram: 8GB G-skill ripjaws 1600mhz
GPU: ASUS GTX 770 Direct CU II / Driver Version: 332.21
PSU: Corsair CX600M
Motherboard: Gigabyte B75M-D3H
Nothing overclocked.

My first instinct was the power supply not being enough for it, or possibly faulty. I updated the BIOS also to F15.

I've ran Prime95 for the CPU, no problems there, everything seems okay.
FurMark however reached about 75% in before causing the same thing to happen with the computer suddenly losing power, noted the GPU reached around 80c. The temps never get that high during games.
So could it be caused by the power supply?
I don't mind searching for a better one (suggestions welcome) just curious whether or not it could be something else.

If I understand it you are blue-screening during games and Furmark? if so it could be any number of things - but if the power supply is OK there is plenty there to power that rig (seriously a good quality 500w would do it) so I would look at overclocking (are you?), latest graphics driver (you using the one that came with it?), or Faulty RAM (I would think not if Prime95 runs OK, but then that will never use all your RAM).
A Starting point would be to ascertain which Games crash and if all of them do (along with FurMark) then eliminate the other causes (Faulty RAM and overclocking), failing all of this RMA the Card - Sorry but thats the best I can do without it in front me.

Hi Olias, thanks for the reply.
My computer doesn't BSOD it just seems to lose power instantly and reboot itself. Nothing is overclocked at the moment, I'm using the the most recent drivers downloaded directly from NVIDIAs website. I ran several games earlier, Tomb Raider and Warcraft to name a couple. They play for a while, but when it suddenly loses power is random, cannot predict when it may happen at all, seems to be about 10-15mins in.

Possible overheating maybe?

You mentioned that you bought the Corsair supply earlier in the month, were you running it with another GPU in the system?

Basically when debugging, I tend to suspect the newest component..... (everything you have SHOULD work fine). And while unusual, I'd suspect the GPU first.

Can you try your GPU in another system?

Try to borrow a PSU to test, sudden power loss during load happens due to a faulty PSU. CX series of Corsair are budget PSU's so not the best, I would avoid CX and VS series.

I bought the new GPU and PSU together on Thursday and installed them in the same time. I replaced a cheaper OCZ PSU and replaced an HD 6870 gpu, i removed all of the old drivers first for it. I don't have another system available to try it, only thing I can do is remove the PSU and put my older one back in.

I could try the one I used previously which is This one, but being only 500w I wasn't sure it would be sufficient for the new gpu.

No problem, you will be fine. A reference GTX 770 will use 230W on max load with 42 Ampere on +12V rail. A decent 500w PSU has 41 A on +12V rail, so you can test with it without worry.

Hi again.
Okay, I put my old PSU back in, ran Furmark now for about 10 minutes, seems to be stable. I'll have to run some games and see how that goes but I guess it may well be that CX PSU causing the problems, guess I'll be sending that one back if so.
Any good brand of PSU you can recommend? I dont mind using this one for now. If it was indeed the CX that caused my crashing, I'd still like to find a good quality PSU for my machine now.

First of all play some games to test the PSU (your old one), furmark or similar software's doesn't always pin point the issue.

Secondly, you said the CX PSU just arrived, so you have the chance to RMA it, do it. If you have the chance to replace it with any other then you can have TX or HX series of Corsair, better ones. If you don't have the chance to swap it, then I would say you might get lucky on the second one.

Else you can go with this one : solid as rock :

Power Supply: XFX 650W 80+ Bronze Certified Semi-Modular ATX Power Supply ($96.98 @ SuperBiiz)
Total: $96.98

Well everything's been fine so far with the games, went and ordered one of those XFX PSU's as well
Hopefully everything should be okay from now on. Appreciate your help, thanks.
