Hello,

I just installed a new system, new motherboard, CPU, Ram. I am having problems with the computer shutting down any time i run high intensity stress tests or benchmarks. I literally just put all this together friday so its kind of fresh. I just finished installing windows 8.1 64 bit. I updated it fully. I have all the latest drivers installed for the MOBO, GPU's etc.

I start up furmark or firestrike from 3dmark and it gets like 10 secs to a min into either one and shuts down cold. Then it starts back up on it's own. I think it might be my PSU. But maybe not. Its pulling 1300-1400 watts at the wall when this happens.

I only have the XMP profile set for the RAM @ 2800mhz which pushes the strap to 125 and the clock up to 3.5ghz

I am running:

iNTEL i7 5960x; ASUS Rampage V Extreme; 16gb Corsair Dominator Platinum 2800 Mhz; (2800Mhz XMP profile set in BIOS and no other tweaks) 4x Sapphire Radeon R9 290 Reference; 1600w "G-Series" LEPA G1600 PSU; 4x Samsung 850 pro SSD(RAID 0); 1x Seagate 1tb HDD; Corsair H100i CPU cooler; Custom water loop through 3 of the 4 R9's (4th one on bottom) Temps never over 55 celcius anywhere except the 4th GPU gets like 60-70 max with fan speed @ 60%

What kind of computer case and when you finished building it did you place the back of the pc right up against the wall? If so you are blocking air flow
 
LOL I really dont think this is an "airflow" issue. My whole PC is underwater.
Case= Rosewill Blackhawk Ultra
 
That sure sounds like a power supply issue, but like muskie suggested, make sure it isn't blue screening.
 
I would go down to one card. If that does ok, add cards until the problem occurs.

If you still have the problem with one card, try a looser RAM profile.
