Other methods include shorting the capacitors with a
screwdriver.  This is slightly crude however, and can result
in the screwdriver being fused to the capacitor :).

There are more elegant devices with resistors in them
designed for discharging capacitors.

I've never heard of PSUs having discharging circuits built
in, though it would seem sensible.
