Feel Like a Complete Newbie Be Gentle - I5-4670K - Asus Maximus IV

I have built a new system with the following specs.

Asus Maximus Extreme IV C2 Z87 (or is it a VI now, I forget ?? )
16gb Corsair Vengance C9
Intel i5-4670K
780GTX Windforce
750w PSU
H100i Cooler
Windows 7

I have been running the system a month or so, and to begin with messed around with small overclock via the boards massive features and easy newbie friendly Windows app that comes with the board.

All seems well with reasonable temps etc (60c max under full load), performance good etc.

Then suddenly my PC started shutting down, no warning, boomp, gone, reboots, no BSOD no nothing. more times than not it would be ingame, but not exclusively, I messed around running back to stock clocks, optimal bios etc the whole 9 yards, turning off power saving features in Bios and Windows etc.

Eventually after much cursing, head scratching and fiddling I found that by running default clock and turning off the Intel Turbo feature in bios I had no more sudden switch off's. Problem sorted.

But now I want to know why..............I have no tried a manual overclock or anything further, don't wanna mess up my system as I use it for work and it is stable ATM, I am a games developer and have been making and overclocking PC's since the days of the old 386 sx 25mhz ! However with this uber fingle fangle Asus board I find myself completely out of my depth with all the settings, and optimal settings is not yielding a stable machine ? I also had to disable the option which detects Power Spikes in the bios btw, not sure if that is related but read elsewhere that is prone to false alarms.

Many many thanks in advance from you clever souls :) 

Please help this confused man, feeling a bit narked as I am not even trying to overclock really and bought the best board I could for maximum reliability !.

Brand new Be Quiet Power Zone 750W '80 Plus Bronze' and a 6 month old 780GTX

All temps low according to systemp all other onboard monitors, generally Core up to around 45c (average games) and 60c under hard load, GPU max of around 80c, these temps seem to confirm with temps reported by BIOS as well.

Power was something I thought it could be, I have 3x SSD, 1 large SATA Drive, CD player, that's it, everything else goes in via powered hubs ?

I have another PSU which I can try sure, it was what I was gonna look at first, been putting that off only because typically its all nicely wrapped and routed in the case.........guess your thinking along the same line ?

May well be something else, but that would be the first I'd look at - no need to remove old and all, set the different PSU next to the case with the case open and just unplug the old cables inside and plug the 'new' ones in and try it

Give that a burn tomorrow and post back, thanks ;) 

Is there a place where all these advanced bios settings can be understood by a mere mortal like myself ??

Never felt so out of my depth with all these additional settings.

Sorry, forgot to post back.

New PSU solved the problems entirely.

The only problem I have now is a random problem with the rtc getting stuck, a known z87 Asus chipset problem from what I have found when researching.

Thanks for the help.
