Power Off/On During Boot

[rickstones]

My new PC build has been up and running for about two weeks now. Here are the components:

ASUS P8Z68-V PRO REV3
i7 2600K (not overclocked yet)
16GB (4X4) Corsair Vengeance
EVGA GTX 580 Classified Ultra 3GB (Core Clock 900MHz, Shader Clock 1800MHz, Memory Clock 4212MHz)
Boot Drive: Intel 520 Series Cherryville SSD120GB
Storage Drive#1: WD Cavier Black 1 TB, SATA Rev 3 (6GB/S)
Storage Drive#2: Segate 500 GB (SATA (3GB/s)
Two Optical Drives: 1 DVD read/write, 1 DVD read-only
Internal USB Card Reader
Hauppauge PCIe TV tuner
OCZ ZX Series 1250W PSU (80-Plus Gold, Full Modular)
CM Storm Trooper Enclosure

A few days ago, a boot issue developed that I've never seen before. After I press the power button, before I receive the POST Beep/Screen, the power goes completely dark for 2 to 3 seconds (seems like an hour), and then it powers back up again and completes the boot normally. It has never failed to finish booting, I just get the little power-down moment of intense terror and trauma.

I initially overclocked the CPU to 4.6GHz and it was stable (ran Prime95 for a little over an hour), but I was getting temperatures in the high 70's, and I received a pop-up notice from somewhere (?) telling me the motherboard was at 0V??). I had no idea what that meant, so I reset everything, and planned to try again another time. The boot problem didn't start right away after this. It booted normally for 5 or 6 days afterward, and then this started happening.

Any ideas?

Why so much power?

mine does this when certain BIOS setting are changed and it has to shut down to change them so I am thinking BIOS related. I'd try restoring default settings or clearing the BIOS

I am planning to add another (maybe two more) video cards if the price drops enough after Kepler... May still be overkill, but I wanted to make sure I didn't have to replace the PSU if I went SLI.

I'll bet you are right. The only thing that bothers me is that it doesn't happen EVERY time. It happens maybe 7 or 8 out of 10 times. I would think that a bios issue would be 100% repeatable. But in any case, I'm going to reset it and see if it goes away.
