Hi. I build gaming computers, and just changed the specifications drastically. What I would like to know, is how many watts of a power supply would I need for this: http://www.u4ik-haze.tk/custom.html if I overclock the CPU to 4.2/4.3gHz and leave all other components at base speed?
See, today, my plans changed to add another GPU, liquid cooling, and various other things. I'd like to know a recommended wattage for the power supply so I don't have to buy one and test it first.
P.S.: the power use of the CPU is 125W at 3.3gHz. the GPU's take about 50W (combined).
For the setup you have listed I would recommend a 1000w-1200w. You could manage with a 800w but it would be running kinda hard at peak. wattage isn't everything though. Also make sure that you have enough amps on all of your rails. I'm running a Kingwin 1000w Mach-1 PSU w/ I7firstname.lastname@example.org / 5HD's / 2x GTX460 Hawks @ 1ghz. I have my pc running 24/7 with no hiccups.
