I've been looking to upgrade my desktop's graphics card to an xfx 512mb 9800gt. The card requires a 400W or greater system power supply (with a minimum 12V current rating of 26A). My current PSU is a XION 450 watt (LC-8460BTX) with the following specs:
+3.3v : 22A
+5V : 15A
+12V1 : 14A
+12V2 : 16A
-12V : 0.3A
+5VSB : 16A
I have no idea how 2 rail systems work vs single rail systems so I'm not sure how the combination of power output works. Do I need to upgrade my PSU or will this PSU be adequate for the graphics card upgrade? Also, if I do need to upgrade, which PSU do you recommend (budget being in the 50$ range)?
