Hi all.
I'm having problems with my new home-built rig, more specifically I'm having problems with the PSU of likes I've never experienced before. I'm hoping that someone here can be of help, maybe give me some insight into what the issue can be.
For good measure, here are some pics of my rig:
Quickspecs:
CPU: Intel Core i7 4770k (Haswell)
Motherboard: ASRock Z87 Extreme9\AC
RAM: Kingston HyperX Beast 2400Mhz
PSU: FSP Group AURUM PRO 1200w
GPU: EVGA GeForce GTX780
OS: Windows 8 Enterprise

The problems with the PSU started when I was all but done with the build. I had been running loop tests (to test for leaks) where only the coolant-pump was plugged in for days, and following that I started to play with overclocks of both the CPU and GPUs.
Everything was fine and dandy until one day I experienced a system crash, so I went into BIOS and removed the CPU clock. After booting back up and doing some diagnostics (which checked out), I rebooted back into BIOS and applied a slightly lower clock (4.4GHz @ 1.3v - pre-set profile by the motherboard manufacturer) and proceeded to boot the system. That's when the first real error occured. The system shut down, a whining noise was played over the speakers (plugged into the analogue motherboard audio ports), and that was it. The PSU was completely lifeless, even tested it by shorting the green/black wires on the 24-pin cable to see if it would start at all.
I went back to the shop and got it replaced on the spot, they didn't even check it for errors. I got back home and put the new PSU (same brand/model as the one that died) and booted the system. Everything was fine. I had to leave it at stock settings for a few days as I was busy work and whatnot, but tonight I was going to sit down and have some fun with overclocking.
I decided to start with a relaxed OC, 4.5Ghz @ 1.25v, but 10 minutes into the stability test in AIDA64, the exact same thing happened again! The system shut down and the whining noise played over the speakers, just like before.
The difference this time is that when I power on the system, the PSU starts up and shuts down in 2-3 second intervals. Hard to explain, so I got a video of it:

In the video, at the 15 seconds mark, you can hear the whining noise that plays over the speakers when I manually shut down the PSU. Exact same sound that appeared when the PSU "died". The clicking noise is probably a relay inside the PSU not working properly? I have no idea about these things.
So! What is going on here? Bad powersupply units? Something wrong with the motherboard that shorts the PSU at certain CPU overclocks?
I have never heard of this scenario anywhere before, does anyone have any clues at all?
I thought I'd check with you guys before I return to the shop on monday to ask for help, it would be nice to have some clue about what's going on here.
Thanks for your time.
