If you guys are talking about AC pumps, then yes, you CAN hook the pump up to the 120V going to the PSU. Problem with this is:

Pump has power applied to it ALL the time.
This is the reason for the relay. The relay is activated when the the computer PSU is turned on which THEN turns the pump on.

As far as 'leeching power' from the PSU, NONONONONO.....the PSU gets 120V from the wall outlet. It's capable of supplying up to 15-20A in most homes. Your typical 300W PSU only pulls a max of 8.5A. Than leaves all the rest for your pump. Even if you tried to pull more than the 15-20A, you couldn't...you'd just trip the circuit breaker.
