Just some questions.
How hard is it to solder a capacitor? It's the first time I'm actually soldering so I'm a bit nervous.
Should I replace only the capacitors that are bulging, or all of them?
It's not hard, and it gets easier if the capacitors you're talking about are big.
Whether you should replace only the ones that exploded and the ones that are bulging or all of them really comes down to whether the ones that still appear good are the same model as the ones that are bulging (better be safe and replace them all in that case) or how old the PSU is. Oh, make sure that the acid from the exploded capacitors didn't corrode the circuit board, otherwise you might have additional problems, like having to rebuild the circuit board with some wires, but at that point I'd just say it's better to just buy a new PSU.
Edit: completely agree with IcedEarth, be careful, the capacitors can hold charge for long periods, so take the precautions he said.
