Great point. I might have to test that out with a Killawatt meter and see what my actual savings may be.

Mainly guessing here, but I don't think you're gonna save too much. The load of the server isn't eaten up by the power supplies, but rather the spinning disc, fans and CPU. Eliminating one power supply will just make the other PS work harder. So, in the event of a power failure, instead of drawing 50% of the power from each PS, you'll be drawing 100% from the remaining PS.

So, all of my servers have redundant power supplies. Thinking of ways to extent my UPS run time, I was thinking maybe I could split off the load of the second power supplies on each server and skip the UPS. Therefore, in a power outage, each server only runs off 1 power supply instead of 2. About half the load on my UPS. I think I can live with that. But how risky is it to run servers on non 'clean' power the UPSes provide? I obviously use a rack-grade surge protector from Tripp Lite or something. Worth the risk? Thoughts?
