Hi guys I'm new here and this is my first post. I'm need regarding my PSU, here we go: I was looking to buy a 9800gt, I currently have the GMA950 (i know, it sucks big time), but then I got informed with the issue that it needs a 400w PSU as a minimun. My PSU is 400w but the 12v is quite low its amperage is 12A. here's what it says on the cover ATX 400W P4 +5V=>30 A +12V=>12 A -5v=>0.5 A -12V=>0.8 A +3.3V=>26 A 5VSB=>2 A I don't know how many rails there is, can it be known from the above? anyways the question that I'm interested in is what card can I run error-free with this PSU; my system is: Dual core 3.0Ghz (930 Presler) 2 sticks 512mb 667 ddr2 (thisnking of upgarding to 2 sticks of 1gb) Intel 945Gz motherboard (gma950 and Realtek audio on board) LG 20x DVD-RW 120Gb maxtor HHD 2 side fanes 12mm So what cards can I get for this PSU, i guess there's no way to handle the 9800gt, can it handle the radeon 3850 or 4850? Please note that I don't care about high resolutions for gaming, 1280*600 is more than enough for me considerning my 15" monitor. Any help would be greatly appreciated.
