    My current PC has a 300 Watt OEM PSU and the manufacturer says any ATX PSU will work.

    So I wanted a new graphics card and it said that I need 26 Amps on my 12 V rail to run it. and 400 Watts. I want to upgrade my PSU and I found a $40 430 Watt PSU on Newegg with dual 15 amp 12 volt rails. Do I just add the amps on both rails up for 30 amps or do i need a better PSU for my video card.

    I want to get an EVGA 9800GT 512MB GDDR3, to replace my 8600GT 512MB DDR2.

    (note: this question is NOT about the PC in my sig)

    I also found a 400 Watt PSU with a single 30 Amp 12 volt rail for around the same price.

    Eva 9800GT is pretty good.
    But you might wanna get 500 watts to be safe (not entirely sure exactly how much an Eva 9800GT takes).

    DO NOT BUY CHEAP PSUS!!!

    Look at reviews, and ask a pro or two. Psus have a tendency to die in a few weeks unless it's a quality one. I've been outta the biz for a little while, but here is a thread that has responses from (mostly) smart people.

    I found an EVGA GTS 250 for $10 less, so does that consume a lot more power?
