Power Supply Clicking

[galaxy]

I have replaced a blown power supply in a pc with one that i found in another.

The PC boots up fine but the problem now is when i power it down, there is a constant clicking noise coming from the power supply and the amber light on the front of the pc is flickering. The only way to stop this is to turn it off at the wall (or remove the cable!)

Is this dangerous, will it cause a problem or will it simply just be annoying.
