how do you hack an AT power supply?
This is a discussion about how do you hack an AT power supply? in the Windows Hardware category; I need a power supply for use for my circuitry project since it has 5V and 12V. I currently have an AT power supply but the problem is that it automatically turns off when not connected to a motherboard.

I think you mean an ATX supply.
The ATX supply design is "always on" with a relay start switch which then closes the circuit.
You would be better using an AT supply that has an actual switch which controls the power and was used in older systems.

In other words, if you connect pin 14 (old-style 20 pin connector) or pin 16 (new style 24-pin connector) - green wire - to any ground connector (black wires), the PSU will start - as long as the power lead is plugged in
