7800GT - Power Supply

[novak]

Hey I have a quick question. When it says on the 7800GT that you need a minimum of a 400W Power supply. Does that mean that you need a 400W Power Supply that is powering the whole PC or a Powersupply that is using 400W of power to power the video card? A video card using 400W of power seems a little strong. I was just wondering because I was going to spend $20 more and I could get a higher GT but the power supply is 450W which is what I have so I was wondering if I'd beable to run the card? Thanks

They mean the whole system needs a 400w PSU so there's enough power to do the video card too. Those things only draw umm.., gah, don't remember - maybe 75w on the high side? (don't shoot me if I'm wrong, pls )

You're good with what you got.

Mike.
