You can discharge the capacitors with a screwdriver and a piece of copper wire.
Get a screwdriver that has a rubber handle (and/or wear thick rubber gloves) and then wrap a piece of stripped copper wire tightly around the metal part of the screwdriver. Put the other end of the copper wire into the ground hole of an electrical outlet.
Then, simply touch the screwdriver to any of the capacitors in the power supply.
NOTE: I have never tried this before and I don't know how well it works. I read about it in a guide to modding monitors, that's how they discharged the color tube.
If you don't want the hassle of that, just make sure you don't touch the heatsink or any of the large capacitors inside the PSU. I've taken a crapload apart to change fans or to remove the fans and use them for something else.
