I am at a complete loss so far for this system crashing. The problem : Playing certain games under very high settings seems to fully restart the system immediately. It will power off, then restart. This does not seem to happen when doing any mild activities, mainly gaming. I can replicate it / cause it almost on cue from playing WoW maxed out and getting to a very graphically intense area and spinning the camera fairly quickly from the ground to the scenery, causing high and low fps spikes/drops.

The system as follows:
Tried with GTX 1080 ti/ R9 290 - no difference between gpus
i5 2500k @ 4.5 ghz 1.3vcore (tested stable) and @ stock (no difference)
G.skill Ram 16gb (2x8gb) 2133 mhz
OCZ zs series 750w psu
Asrock extreme 3 gen 3 z68
crucial mx500 SSD 500gb (swapped SSD's, no difference)
seagate 1tb
Windows 10 (done fresh installs)
Corsair PSU calculator puts my system at 610 watts under max load, assuming 100% tdp.

What i've done / tested so far:
-Looked at temps, nothing has gone out of control under load, i.e cpu < 60c at load, GPU < 70c under load.
-Ran memtest for approx 45 mins, not to 100% but 0 errors.
-Ran prime 95/ IBT/ cinebench for quite awhile /many blends, no crash yet.
-Ran GPU stress tests, furmark, 3dmark /heaven/super position
-Checked HDD/SDD for errors (though i've since swapped SSD's and it persists)

Any thoughts/ideas of what I should do next for this system? I'm planning on selling it but don't want to get rid of a system that just crashes upon heavy loads.
- I'm unsure if it could be the PSU since it crashes both when OC'd and not OC'd, which should have a large enough drop in power used.

I'm so lost!
 
If the system reboots when taxed, the issue is the lack of ample power being delivered by the PSU. You also have a unit that is known among the PSU community as an expensive paper weight. how old is the unit, mind you? Capacitor aging will also negatively effect how much power it can output. If it's been under stress most of the time, then you have a much lower power outputting PSU.
 


The unit is roughly 3 years old. Is it safe to say its the PSU? I've tried removing additional equiment. I.e having only 1 SSD instead of 2 ssd 2 hdd. Still crashed. Not much else I can remove.
