So I got my Asus board this weekend and to my surprise when I was hooking everything up I noticed that the power supply connection was 24pin. After much research and talking to my friend I was informed that i was able to use my old 20pin Antec 430watt PSU and that it would work fine. So i tried it and to my surprise it worked! I have tested it for about 3 days now and everything seems to be stable (knocks on wood). Been playin games and such for a few hours and leaveing 3DMark01 all night in loop mode with no problems.
My question is I currently have only one evga 7800gt hooked up. If i want to go SLI, do i need to get a new 24pin PSU or will a new 20pin PSU work fine? (Buying a new PSU when I do SLI as I don't think 430watts will cut it). And what PSU will be good for this board useing SLI?
