PC suddenly reboots when under load then proceeds to get stuck in boot loop without posting

[grimsonfart]

So lately my PC has been acting up big time, the title explains it the best. It happens under any kind of load i have tested, from benchmarks to stress tests to just gaming. Basically shuts down, no errors or BSOD, starts right back up again for a few seconds then shuts down, and starts back up rinse/repeat.. If i'm lucky when it starts up again it actually posts and boots properly, but that's quite rare. Leaving it off for a minute or two usually does the trick until i start doing something other than browsing the net.

I have checked temperatures of both CPU, mobo and GPU all being fine.. I have reset CMOS, unplugged all my HDDs leaving only my M2, removed/switched RAM positions and i ran memory diagnostics etc.

Pretty sure it's a PSU issue considering i have a Corsair CX650. Already contacted their customer support in regards to getting a replacement unit.

Seems like you cheaped out on PSU, why else you'd be using a PSU that at best is mediocre quality (Tier three) PSU which barely supplies enough wattage for your build.
PSU Tier list: http://www.tomshardware.co.uk/forum/id-2547993/psu-tier-list.html

Your CPU and GPU alone, without any OC, consume 400W. Total build would consume about 530W, with OC, even more. 650W PSU for your workstation build is a bit less and i'd be more comfortable to use at least 750W great quality (Tier one) unit.

That being said, for new PSU, i suggest going with Seasonic PRIME 750 80+ Titanium (Tier one),

or if your build theme is white then Seasonic Snow Silent 750W (Tier one) with CableMod white cable kit,

Seasonic PRIME series is the best PSU series offered by Seasonic. PRIME series PSUs are also the only PSUs in the world that come with 12 years! of warranty. My Skylake build is powered by PRIME 650 80+ Titanium, full specs in my sig.

Well your definitely not wrong about the bad choice. I bought it in a bit of a rush since i had just moved to a new country so just took the first thing i spotted, and i honestly have had only good experiences with Corsair PSU's. My last one was an RM850 and prior to that a CX650 again.

It could also explain the poor OC i'm getting out of my 6800k, anything above 4.1ghz and it BSODs within 10 minutes..

I'l see what i can get out of my warranty, not sure if money back is an option, maybe i'l just get a new unit and sell it buying a better one.

Thanks!
