I'm in past my abilities on this one. Can a 400 W Antec ATX 12V power supply, unswitched except for an on/off switch on the back, work on an old Amptron motherboard, a PC that came with a switched power supply?
Background: I'm having strange system crashes plus intermittent "blackouts", the PC turns off and on by itself (no flicker from the desk light attached to the same outlet). I'm thinking maybe I need a new power supply and go to my local computer store. They have no switched power supplies, which is what the PC was built with 5 years ago. I got the Antec, thinking it might work, get home and put it in the PC. Nothing. Completely dark. The on/off switch on the back does nothing, no fan, no power.
It looks like the power supply is looking for a signal from the motherboard to go "on". I may just need an explanation of how switched vs. unswitched power supplies work.
thanks!
