Ok, im upgrading from a PNY 6200, and 512 RAM. To a Evga 6800, and 1 gig of RAM. And i was wondering if my 450W power supply will be good enough. The only thing im worried is about the 18A on the 12V line. Just dont know if that enough.

It will work perfectly with no problems.

Are you sure? Not to be rude, but im wondering if your just basing your answer on that its a 450W? Cus in my experience, and what my uncle tought me, wattage means nothing compared to the 12V line.

All PSU support 12V lines:

Output: +3.3V@26A, +5V@30A, +12V@20A, -5V@0.8A, -12V@0.8A, +5VSB@2A

Lol, i know that! I was wondering if +12V@18A was enough!

It's enough. I wouldn't really get too paranoid over this. Measurements from a 6800 uses like 5 amps on a 12V rail so your power supply should be more than adequate for that video card. Just make sure to use a dedicated plug directly from the power supply instead of off of another molex plug from another device.

I'm using a 7800GT which requires more power and I'm only using a 450watt power supply at these specs:

ASPIRE CONCORD ATX-MR450W ATX 450W Power Supply 115/230 V cUL, FCC, CSA, CB, TUV, CE, NEMCO, DEMCO, SEMCO, TC - Retail

Can't run any better.
