Yes, I will be using 12VDC from my PS to turn the relay on.

But I believe the switch MUST swich the AC line. If by low voltage you mean the DC signal, and I wired the relay up on the DC side then I THINK the switch would just alternate between:
A) when computer is on, pump is on
B) pump is ALWAYS off

I might be wrong though... I'm a newb. Someone clarify please.
