hello everyone, I'm new to techspot, and it's one of my favorit sites now! anyways here is the problem: after some advice from some of the techspot smart guys, my power supply is bad and needs to be replaced. The brand is a easy choice, becasue of all the links provided by everyone here at techspot. however my next question is how many watts do i need? what info is needed? basic info: i have => a vid card, 1gig of ram, 1 hard drive, 1 dvd drive, 3 1/2 floppy, ethernet card, 3 large fans about 5", 2 small fans about 3 1/2" , on and off switches for each group of fans 4 switches total, some extra usb ports connected with the mobo.
