Got a question here. I want to get an Antec case. I am getting an Asus mobo. and P4 1.6A processor to go in it. Do I need the 400W power supply of the 1040B or is 300W in the SX1030B enough? I also considered Enermax and they are in between on watts somehwhere I think. Please let me know if I should play it safe and go 400 watts or if I am wasteing money. Thanks all.
