Will i have enough power?

[Blue Cypher]

I am going to SLI 2 6800GS graphics cards in my new pc but i obly have a 480 watt power supply. It is a very good one (Antec true power 2 480watt) i spent £65 on it so its not a cheap naff one, but will it have enough power to work the 2 graphics cards?

Thx in advance for any replies

That will partly depend on what else you have running in your system but assuming a basic 1 hard drive, 1 optical and other normal components with no or minimal overclock yes it should cope ok.

I have 2 cd drives, 1 hard drive, my processor is overclocked its a 3700+ 2.2Ghz overclocked to 2.81Ghz, but i didnt think that would take up much more power
thx for reply semi-pro
