I recently purchased 2 Ultra power supplies from Fry's in sealed boxes, one a 400W one a 500W. Should I be able to detect any voltage on the plugs without connecting them to a motherboard? There is no power-on light on either unit, the fans do not spin up when I plug them in, the power cord is good. I switched them both on/off with a working voltmeter connected to either 12v or 5v pins, no voltage detected on either supply. Both set for 110/120 volts as well.
