Hello.
My pc reboots during Valley benchmark, always in the same spot. 12 or 13 test(i am not home to say for sure now).
I found this out when trying to get safe overclock values for my R9 280. The thing is, it restart regardless i overclock my gpu or not. What could be the problem? I see CPU temps are up too.
So GPU rises to 70 degrees(80 if OC) and CPU goes up to 70-80 degrees.
I have the following setup:
PSU: Corsair VS 550
CPU: Intel i7 4770 Stock cooler
MB: ASRock B85 Pro4
GPU:MSI R9 280 3GB Gaming Edition
Memory: 2x Kingmax 4GB 1333 Mhz
Storage: 1x120 GB Kingston v300 SSD NOW edition. 1x2 TB Seagate 7200 rpm HDD
Sound: Asus Xonar DG
Case: Super Flower SF-701N Black
Could it restart because of the CPU ? Or PSU ? How am i supposed to determine the problem?
Thank you!

13 = 2013.

37 = 37th week of 2013.

RMA the PSU. After some SI's decided to use the VS with some graphics cards that were a bit higher end than what the marketing folks at Corsair thought would ever be used with a VS level product (seriously? $300 graphics card with a $50 PSU?) they found out that the VS couldn't support the very sudden power swings a high end graphics card would cause when going from idle to a benchmark like Unigine Valley.

Instead of telling the SI's to not use the VS and to use something better, they decided to figure out what part they could beef up to make the VS handle these extreme and...
Time to post the results:
I got home and i switched the Video board from the lower slot to the upper one(closer to the CPU). I started testing again. This time i was able to OC until i reached GPU - 1050 MEM - 1450. After that i got a restart.
I unchecked the automatically restart thing, but after all the tests. Maybe if i run into problems again i will be able to get some feedback. Also the CPU temps got really high. it reached 90-99 degrees in the first tests and 80-90 in the last ones(where gpu / mem clocks were higher).
S/N of the PSU is 1337........... Really it start with leet :). By the way, what is the deal with the serial number?

LE: I tested my pc for 8 minutes in Prime95, using Blend > Torture test. Temperatures were 98-100 degrees, but i got 0 errors, 0 warnings. and no reboots. So i think i can rule out CPU being faulty or something like that.
My guess would be the PSU or the MOBO. but how do i check?

Instead of telling the SI's to not use the VS and to use something better, they decided to figure out what part they could beef up to make the VS handle these extreme and sudden power loads. They implemented this "fix" in VS units made after the fifth week of 2014. So you would want a serial number of 1405 or higher.
