Should be plenty of power to run the card, if you look at the numbers

The PSU lists: Output +3.3@24A,+5V@24A,+12V1@18A,+12V2@18A,+12V3@18A,- 12V@0.8A,+5VSB@3A
The 3 +12V rails are 18a EA, total of 54A; usable ~ 45A give or take

The Gpu lists: Minimum 400W or greater system power supply (with 12V current rating of 26A) So you are looking good.

That is how simple it is to read the specs on a PSU

oh i see, so you add each rail to the total amps? Thanks for your quick response and help.

only part way, total Amps is never maximum amps, you add the efficency and other factors, roughly figure 75% of total. Better units even list both on the side panel of the PSU

Read the PSU 101 & 102 sticky in the power supply section, it explains everything, including a much more accurate way of calculation the total amps.

That psu has 40a on the +12v rail, more then enough power for your system.

Insight: The capacity to discern the true nature of a situation

I'd say so.
