Hello people!
I currently have a little problem, I don't know how to choose my power supply unit. Do I only need to look at the watts? Or is some power supply unit not compatible with some processor? Well, here's some of the pieces of my pc :

Sapphire Radeon HD 5770 - 1Go
i7-950 intel
CORSAIR CMX8GX3M4A1600C9 - DDR3-1600 - 4 x 2GB
ASUS P6TD Deluxe Intel X58 Socket LGA1366
Barracuda 1 TB / SATA II / 7200.12 / 32MB Cache
XION vantage case
Random DVD reader

I will not upgrade to a dual video card, I may have multiple fans (2x 120mm) and possibly a better CPU cooling thing too.
Is 500W enough for the power supply? Because that would be just perfect for me.

A big thanks to anyone who will help me,

From AMD's website the following power supply requirement is specified for the ATI Radeon HD 5770:

  • 450 Watt or greater power supply with one 75W 6-pin PCI Express power connectors recommended (600 Watt and two 6-pin connectors for ATI CrossFireX technology in dual mode)

    Yeah, I saw that, but i wasn't sure if it was all I needed to take into consideration. If it is, then it's fine with my 500W :D !
    If anyone have another opinion, tell me :) 

    Thanks Ko888 ;)
