It is conceivable, but I've never heard of it happening.
I'd go ahead and do it, but of course I don't accept responsibility for the results!
If you have a working 1.8 Amp PSU, I'd use that... it's more rugged than the 1.2 Amp version.
The clicking PSU is either a short circuit or its voltage set too high.
You could look for a short by opening the back and checking the resistance to ground for the various power supply output voltages accessible on the I/O board. If there is a short but you can't isolate it to one board in the card cage, then its probably inside the PSU.
