Yeah, it's only 20 amps. Also it's happened once or twice with me now, when i turn on the omcputer and it loads ir is about to go to the windows welcome screen the computer kinda makes a high pitched sound and restarts the computer, not enough power to handle probably, or not enough to give. Well it has turned on now, and working, and i guess i got to use it till i go to the shop and send in my dismantled PSU. Maybe i should buy another generic one that has sufficient ampage on the 12 volt rail. Check out my setup, how many amps do you reckon it needs?
