well i was wondering what would be a good power supply? is it better to have dual 12V rails or just one? i need the 12V rail to be at least 18A or more so as far as i can see that most power sources are less then 18A for the 12V rail if its under 500W. ive been searching newegg and i was looking at either the one thermaltake for $40 thats like the main one that sells or some of the rosewell psu's around $50-$70. i dunno i don't want to spend a fortune on a power supply just a decent one with enough power to run everything and be fairly reliable.
