hello i have build one monster of a pc and sadly when i turn it off overnight and turn it on the next day it will not cold boot, and if it by some miracle does, it restarts after one minute and does a infinite reboot. so i figured after alot of research that the psu was faulty. however im am now wondering that maybe i under estimated my psu, and i need to know if i need a higher wattage psu. So.. specs:

cpu: 4770k (i dont overclock, i used to, realized it was a waste of power and cpu lifetime)
ram: Corsair Dominator Platinum 16 gigs 8 x 2
mobo: MSI z87 gd-65
GPU: 2 EVGA GTX 780ti sli
drives: 256 samsung ssd 500 gig samsung ssd and a 1 tb hard drive
optical drives: 2 dvd combo drives
water cooling: corsair h100i cpu liquid cooler
and a fan controller with 7 fans on it

so i think this is everything that would matter for power consumption. Now my PSU is a corsair rm 1000w modular PSU, now i thought this was about 100-150 more plenty then i need, but after some psu calculators i think i might be wrong so if you would please give me an estimated wattage that would be the best. Thanks all!

The Corsair RM series is not high on my list of good psu's, although there are some who do like them. That said, for a sli gtx780ti build the generally recommended minimum is a quality 850w psu from XFX, Seasonic, Antec, Evga or Corsair AX-HX etc. That's absolute minimum. For safety, comfort, etc, 1000w is better, tier 1 or 2 psu's. Right now the Evga G2 1000w is about the best in its class, and if you were to buy a new psu, its one I would highly recommend.
