Okay so I just got my new graphics card, GTX 670 FTW edition.

The graphics card I had prior is the HD 6870, which ran fine with my AMD Phenom II X4 840.

Now, I'm wondering... Because I just put in the new GTX 670, but whenever I put load on it - my computer shuts off instantly.

I tried it and monitored the GPU temp and it didn't get above 52 Celsius, so I know that's not the problem.

I have a 650W power supply, and the recommended is a 500W minimum for the GTX 670, so I can't see why that would be the problem either.

Could it possibly be that my CPU is just too bottlenecked?

Which leads me to think that perhaps the GTX670 uses more power than your 6870. Or perhaps its the graphics cards maybe you can call the card manufacturer and see if you can get a replacement especially since you have a EVGA card you should have no issues with that.

It's hard to say can you be a bit more specific with your setup

CPU: AMD Phenom X4 840
RAM:
GPU: EVGA GTX670
PSU: Manufacture/Model No.
Motherboard: Manufacture/Model No.

My guess off the top of my head is there is a power issue here if your other card has no issues then I would think it would be on the power end of things but yea please help me help you with your system specs and see what I can say to help.

I have G.SKILL Ripjaws Series 8GB RAM, PSU(I don't know, just know it's 650W), and my motherboard is ASRock 960GM/U3S3 FX

It's made by Blue Star, and it says.... DC Current: +3.3V(30A), +5V(32A), +12V(35A), +12V(0.5A), and +5VSB(2.A)

I tested my PSU and nothing is wrong with it. I have my previous HD 6870 in my PC right now and I can benchmark and run stress tests all day with no errors. But as soon as I put the GTX 670 in, instant shut down on any test.

No its quite alright something else you may want to check is your driver version I hear there is an issue with the current nvidia driver that has been causing issues apparently. I reverted to the WQHL driver prior to the one thats out now.
