Is current PSU not enough?

Hi All,

Recently I built the following system, some parts were from my previous build namely HDD, Case and PSU.

New Parts:
Intel Core i7 3930K
G.Skill 16GB (4x4GB) DDR3 Kit, PC-12800 (1600Mhz), RipjawsZ, 9-9-9-24-2N
Asus Rampage IV Formula, X79
Gigabyte 7970 3GB x 2 (Crossfired) Cat 12.8
3 x 23” Samsung LCDs (5760x1080)

Existing Parts:
2 x WD 500GB HDD
1 x OCZ Agility 3 120GB
1 x OCZ Agility 3 240GB
Thermal Take tough power 850W
Raven II case

OS Win 7 64bit Pro

Now the the issue I have is the system locks during gaming, usually after about 15 min or so. I can't even use the reset boutton on the case, I have to physically cut the power.

With general apps like Firefox for example I'm getting corruptions in the text and then a black viewing area, with IE9 I'm only getting corrupted text.

With 2 x HDDs, 2 x SSDs, 2 x 7970s and 4 x 120 fans running, do I need beefier PSU?

  1. That's one of the few good TT PSU's and it has plenty of wattage, even for that system.

    My guess is that it's a driver issue.

    Failing that, possibly one or both of the GPU's themselves is faulty (or dying, even if they are new).
  2. did you do a clean install of windows when you transfered the storage over?
  3. what is with the doubles posts on this forums :P
  4. Yeah clean install of everything. I went from Win7 home to Pro due to the memory increase.
  5. Best answer
    Yeah, I would uninstall the drivers for the 7970's and try either an older version or just a re-installation of the current non-beta version.
