    Is there some reason you think it wouldnt be good enough?

    I believe that has 4 12volt rails.. not my favorite setup.. but provided its properly hooked up and load balanced correctly it should be fine.

    Does have 4 12 volt rails, correct. Just asked cause had some freeze problems on occasion. Checked numerous site calculators and out of the 10 i tried, i found 2 that said it might need more towards 850 to 900 of course assuming max load. (rest were mainly about 650 on avg). CyberpowerPC built it originally
  3. If it was a chep unbranded PSU you would be more likely to have trouble.
  4. Also, It may say 800 watts but thats MAX. It might not be continuous power so therefor its probably only running at 600 or so and Occasionally spikes at 800. I recommend Antec PSU or a nice corsair, just make sure its continuous and try to stay away from 4 rails unless you know how to set them all up correctly
  5. I would check the wiring of the PSU and make sure each GFX card has its own rail on the PCIe power connector and also make sure they do not share a rail with the motherboard. I think you should try some basic diagnostic tests first such as monitoring temperatures, check ram with memtest86+ and check hard drive with the manufacturers diagnostic utility. Also, if you have never cleaned the dust out of the computer and PSU during the time you have owned it, I suggest you do it. Dust getting caked on components can cause them to overheat in certain spots.
  6. Unknown brand PSU....I doubt if it will perform to its specs.

  7. its not an unknown brand psu...its NZXT as stated
  8. ^ Yes, but NZXT dosen't exactly make the top of the line PSUs. If OP can afford it, he probably should look in to a quality SeaSonic, Corsair, PC Power & Cooling, Antec (non the Basiqs) or XFX.
