Lost power or VGA?

[Sazto]

Hello everyone, I got a system for 5 months:

- CPU: Intel i7-2600K
- Mainboard: Asus P8Z68-V
- RAM: 4 x 4GB Gskill DDR3 12800/1600
- VGA: 2 x MSI 560Ti Hawk
- Cooling: Corsair H100
- Case: Cooler Master HAF X 942
- SSD: Patriot Memory 120GB
- HDD: WD 2TB Black
- PSU: Enermax Naxn 82PLUS+ 850W

Last few months, I just used it for AutoCad, Photoshop etc. Generally, all of them was basic stuff.

A thing has been happening since last week when I start to do some heavy stuffs like 3D rendering, film rendering and playing some games like Company of Heroes, Call of Duty, Crysis etc. At the first time, nothing happen when I set Medium Setting. But when I changed to Ultra Setting, it was restart automatically after 2,3 hours.

Then I used some testing software like Intel Burn Test, Cinabech, FurMarks..... and it happened again when I was using FurMark (VGA testing)

Could you please give me some ideas what;s going on?

Thanks in advance.

Hard to tell but try the testing with one card at a time! If no problem then it could be your PSU!
