I have originally wondered about the server PSU possibility. I got a good deal on my rosewill lighning 1300 watt($139) and my Corsair's($49 for the 750 watt 80plus bronze) ($29 for 600 watt 80plus Bronze). The reason I didnt do the Server PSUs was I couldnt find the breakout board option for sale at the time and I couldnt find info on efficiency.
How is the efficiency of the Server PSUs as compared to the 80+ Bronze, Gold or Platinum ATX PSUs?
Also, is it any easier on electric and/or heat to run on 220/230 volts AC as opposed to 110/115?
Server PSU's are generally at least 80% efficient, and this 2000w one is 90+% at 50+% load.
not sure i fully understand your question about "easier on electric and/or heat" but things run more efficiently (ie lower overall watt usage) on higher voltage because they require lower amperage which means less of your electricity is converted to heat (due to resistance). if you want to better understand this link may help (or may just confuse your more) -

V (volts) x A (amps) = W (watts)
I was wondering about the 220/230 vs. 110/115. I ask my father n law about this and he always refers to that same formula. Why are appliances(dryers for example) always 220/230 rather than 110/115? Whats the advantage? It seems like a disadvantage as you would have to run a 220/230 circuit? Some have told me in the past that appliances run on the higher volts as this makes them more efficient. We just wired my trailer/mobile home with new circuits to avoid me burning the place down. We ran 110/115 runs. We also stepped up the incoming feed from a 100 amp main to a 200 amp main. Does this mean there is no advantage to running 220/230? Sorry if this seems dumb. I just dont get it.
What I mean by easier on electric is Use less, and what I mean by easier on heat is produce less heat/
