Hd7970 vapor-x problem (restart while playing games)

Hey guys, i recently bought my new pc:

MOBO: Gigabyte G1 Sniper M3
GPU: Sapphire hd 7970 vapor-x
CPU: i5 3570k
CPU Cooler: Corsair H50
PSU: Thermaltake tr2 rx 1200 (i already had it from my previous pc) http://

Install Windows 7 64b: no problem.
Instal Drivers (Updated): No problem.
Instal GPU Drivers (Updated): No problem
Update Bios: No problem.
Stress test RAM and CPU: No problem

then, i decided to play Sniper Elite V2, but in some point of the game (between 7-15 min) my pc shut down and restart. I said.... well, at least i can play league of legends, so i install.... create a match, and when the game starts, 5 seconds later another shutdown and restart.
The temps are all good (all the temps are in IDLE)

And here is what i dont know if i need to replace my PSU or need to change voltages.
My GPU-Z:

And this is from a review:

if u compare my VDDC Current and VDDC from the Review, there is a lot difference
If you need another information just say.
i did a stress test from the GPU and shutdown/restart almost instantly ( 2/3 Seconds)

said that, i appreciate your help. Thanks so much.

  1. Best answer
    Shutdown is definitely a PSU issue. Graphics cards will generally turn off the screen, or leave the system running for a full hang, or bluescreen. Full blown shutdown and restart is Power supply. Go to some store, buy a decent 550W Power supply from Antec, Corsair, Seasonic, Enermax, Silverstone, and see if it works. Make sure it has enough connectors too.
  2. ok i will try buying a new PSU and see what happens.

    Thanks for the answer
  3. Shutdown is not necessarily a PSU issue. In fact, it worked previously so I doubt it's the cause. There are several possible causes.

    You should at least run MEMTEST before troubleshooting further.

    While his Ram might be faulty, it still wouldn't cause a shutdown. I had the same issue with my old GS800 from Corsair. Would shutdown immediately after going under load, and I basically did a full reinstallation of my OS, drivers and everything basically. Ended up just sending back the PSU because I had nothing else to do, and when I got the new one, it worked. However, my original, faulty PSU would work only with a single GPU, and I was reading 10.93 V with a Digital Multimeter under load with a single card (Wouldn't even expect it to boot with that to be honest), and when a second GPU was in it, it would shutdown immediately. New PSU worked.

    tldr : Basically, even if it worked previously, it could be, like in my issue, due to the fact that you never put it under enough load to stimulate the issues. What was your previous rig?

    Considering the PSU appears to be a 1200W model, I highly doubt it's the issue. It's possible, but I would guess the problem is one of these in order or most likely to least likely:
    1) Memory (timing issue or defective)
    2) Graphics Card
    3) Motherboard hardware
    4) Motherboard BIOS issue (requiring firmware update)
    5) Power Supply
    6) other

    If Memtest passes, the next step might be to either try a different graphics card if possible or try that HD7970 in a different PC which has a PSU with the proper 6-pin/8-pin connectors.

    My Previous rig was:

    MOBO: Asus Rampage III Extreme
    RAM: 6gb Gskill 1333
    GPU: hd5970
    CPU: I7 960
    same PSU: Thermaltake rx t2 1200w

    i did a memtest and all is good. in fact, i change my GPU and test with the 5970, and can do all. i will buy a new PSU and le u know.

    Thanks for reply, i test everything. even update bios to last version. iI will try buyng a new PSU. in fact, i did a AIDA64 test, and micro, cache, memory, all working fine, and when i tried to test the gpu, the voltag fall down (in the graphic) and pc shut down and restart.
  8. Is your PSU still under WARRANTY?

    no, but i solved the problem. Was the PSU. i bought the Cooler Master Silent Pro Gold 800w, and all is good now :)

    That's good. I had a very similar issue and fixed it the same way.
