So it isn't all about watts

  1. With todays PCs what's the normal current draw for each of the rails in a power supply? Let's say my specs is as follows:

    A64
    1 gig ram
    1 harddrive
    geforce 6800

    I've seen 500 watt power supplies with 10 A on the 12 volt and yet on 300 watt power supply it's 15 A. I certainly don't want to get a $100 power supply if it can't provide the current.

    Here is an excellent thread on PSUs. I'd say for the system you are looking at you're going to want about 24a on the 12v rail. And better yet, get a dual 12v rail (with 12-18amps on each).
