I want o use an AT supply for some DC projects.

I think i need to short a couple pins on the motherboard connector
to get it to start up..

does anyone know?

and what kind of amps will those put out?
 
AT power supplies are not like ATX, they are not started up by the motherboard when you press the power switch, when you hit the switch, it turns on the power supply directly.

If you are looking for Amps, check the PSU itself, each one will be different.
 
Be aware that most AT power supplies require a minimum load be present in order to function properly. They really aren't good general-purpose power supplies.
 
AT power supplies generally have the switch hard-wired to them. The switches are either on or off, unlike the mommentary contact switches used for ATX. They do usually require a load to run stable, but it does not have to be a very big load. I fooled around with one once and used an ancient 106mb hd as a load that seemed to work fine.
