My computer suddenly cut off after being on about an hour. I suspected the power supply and so bought a new one. The machine still does nothing when I turn it on.
I tried running both power supplies directly on the bench. Both times I plugged it in, turned it on and the fan did not come on. I didn't take voltages across the connectors, becasue I assume no fan means dead power supply or at least it is not turning on.
Should I be able to simply test the power supply disconnected from the computer by merely plugging the AC voltage and flipping the switch. I thought yes, but since neither supply worked, would like an answer from someone who knows?
