You need two for certain configurations. I believe you can run it with
two CPU boards, two memory boards, and one of the internal drive towers
full before you need a second supply. There's a jumper on the system
board that configures the system for two-supply or 1+1 operation.

Oooh. Are they EV4 or are they EV5?

You will. The system Will Not Start with that many cards on a single
PSU. It will try -really- hard for a few seconds, power down, and
refuse to try again until you give the PSU time to reset.

If one of those cards is an EV5/250, I might be interested in buying
it. That'd bring my two systems into parity.
