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

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

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.

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
