I've got a standard AT power supply that I want to rig for use as a regular power supply, i.e. for non-computer use. DOes anyone know how I would do that? (do i need to short certain pins on the motherboard connector or something? I couldn't jsut turn it on.)
I made an awesome fan array from case fans and power supply fans, and I want to hang it on my ceiling. I connected it to an AT power supply, and when I switched it on, the fans turned on briefly and then died. I tried plugging in the power supply to a motherboard, and then it didn't even turn on. I even tried connecting the 5V pin to the power good pin. Anyway, is the power supply probably funked up, or what? Could it have been wierded when I sprayed out the entire inside with a compressed air can? (ugh...dust everywhere...in thick globs...)
Some late model AT power supplies had a smart switch which would detect the motherboard. I've tried for HOURS to figure out how to disable it. The other solution is to use an OLDER style AT power supply without the smart switch.

When I turn it on without anything plugged in, it doesn't start up. However, the fan starts twitchting every second or so. I mean like literally twitchting. NOt going a few revolutions and stopping, but just a small twitch (or large quiver). Maybe a fuse is half-blown, or some capacitor is busted? It semms that maybe it isn't "charging up" properly? (the capacitor, that is)
AT suppies normally need a load of at least 1-2 amp on the +5V to operate, which you can provide with one 5 ohm, 20 watt resistor or a pair of 5 ohm, 20 watt resistors in parallel. 10 ohm, 10 watt resistors are more commona and can be combined in parallel for identical resistance and power ratings.
