What PSU do I need?

[Tatoze]

Hi there

I am currently in the process of building my own computer,
mainly as a learning experience.
However, I do not know which power supply I should get (wattage).

I have chosen out these parts;

MotherBoard X79 extreme 4*
CPU Intel Core i7-3930k @ 3,20 ghz
Cooler Corsair hydro H100 CPU LIquidCooler
RAM Corsair Vengeance *DDR3 1800Mhz 16GB
VideoCard Gigabyte GeForce GTX 580
SSD OCZ agility 3 series 120GB
HDD SeaGate Barracuda Green 2tb SATA3
Mid-Tower CoolerMaster Storm Sniper

Ill upgrade a gtx 580 later, so please can anybody help me out?

Are you saying you're thinking of adding another GTX 580 in SLI in the future?
For a single card you probably need 650-700W, for SLI 850W or more.

Yes im thinking of adding a second Gtx 580 in the future..so if i buy a 850w PSU is gonna be enough power for 2 gtx 580? Or better buy a 1000w straigh away??, thanks for helping btw

I would say just get a quality 1000W PSU, will future proof you for a long time.

I agree with @SLH28 850W+ will serve you well. Here is a good one I found on newegg.

You might want to look into grabbing a Full tower instead of that mid- tower. I say this because you may be packed a little tight in there once everything is in. Especially since you do plan on going for a SLI GPU setup.

Definately suggest a 850+ watt quality psu. Silver or Gold rating.

Corsair, Silverstone, Ocz zx, Thermaltake.
