more than likely the psu from your friend's old build.

If there's no response at all when you press the power button, then I would suspect that the following may be at fault:

1. You forgot to connect the power switch, or connected it incorrectly. It's embarrassing but it happens to everyone at least once.

2. The contacts on ATX connectors aren't always constructed all that well. If your friend's PSU is cheap, has been used for a while, or has been connected and disconnected from motherboards repeatedly then one or more of the 24 pins may not be making proper contact. Try playing with the connector a bit. I have an old PSU from Thermaltake which has this issue.
