8800GT OC PSU requirements

[cair]

I've read other threads about this but i still don't quite understand, i recently bought an BFG 8800 GT OC and it's system requirements for PSU are 12V combined with 28A or more, i didn't quite understand that either, i was confused with the watts, it required 425 watts and my PSU states 500 watts maximum, however, it showed +12 combined with 20A only, and im sure that does not meet the requirements, a little advice and wisdom please!. im considering buying a rocketfish 700 watt powersupply.

450w @ 26amps for the 8800GT
Do not buy that psu.
here's a suggestion:
450w @ 33amps

buy the Corsair, you can't go wrong.

so basically the v12 at 20 amps isn't enough?
is this okay? http://www.rocketfishproducts.com/pc-62-3-rocketfish-700-watt-atx-cpu-power-supply.aspx

Best Buy brand ( AKA Rocketfish ) power supplies are garbage.
