First Time Build

[Raizen]

Hi guys, i am going to be building my first gaming PC, I plan to use it to play games such as Final Fantasy 14, Crysis, Stalker and watching movies etc.

I do not plan to overclock this system anytime soon as i am not very experienced with this yet.

My main question really is would my power supply be sufficient to run GTX 480s in SLi sometime in the future? my research has shown each card pulls around 400w, anyone able to expand on this?

All help and advice is appreciated, thanks.

that spec is fine.

a GTX480 and system its in will be 400w, not just the card on its own.

so you can't just double this number when you add a second card, the psu will be ok.
