What im working with:

Cooler Master Stork Stryker Case
Gigabyte Z77X-UD5H
Two Evga Nvidia Geforce GTX 670 (Superclocked)
Intel i5-2500k cpu unlocked (eventually will be OC'd)
One Samsung 250gb SSD 540 read speed 250ish write speed
One WD 1tb HD
One Samsung CD/DVD reader
One Samsung CD/DVD Burner
32gb RAM

Water Cooling System (all from Koolance):
One 2x120 Radiator - HX-240XC
One 2x120 Radiator - HX-CU720V
Four Radiator Fans - FAN-12025HBK
One CPU water block - CPU-380I
Two GPU water blocks - GPU-220
One Reservoir - RP-452X2
One Pump - PMP-450

3/8 tubing

I figured about 1200-1500 watt psu, could use further input. Thanks, much appreciated.

Almost all of the power draw comes from the graphics cards. A quality psu of 800w should be plenty.

Really? bc I was reading on what some other people had and for 2 SC GPU's they were saying at least 700w and if I was planning on OC'n my CPU I'd want at least another 300w

But you guys know better than me lol

Oh last question say I buy a 1000+w psu would that damage my system. I've heard you have to be prtty close to precise when it come to your psu

Not at all. You need about 600 watts on your 12 volt rail at most with that setup. A good 850 watt PSU will still leave you with 250 watts of overhead. A higher wattage PSU will not damage your system at all, it will just cost more.

Best solution
