If you are thinking of the UPS route a caveat: I have several HP servers and most of them will not work on cheap UPS's as they do not produce the pure sine wave modern HP machines require but rather a crude stepped voltage.
perhaps naively, I'm surprised: doesn't this mean they put crappy PSUs in those servers? I thought decent PSUs were expected to deal with dirty input AC?
I agree. Esp. since, other than in datacenters, *most* electric power is pretty crappy.
I would have to disagree. They probably put high efficiency active PFC power supplies in the servers to save YOU money. You could buy a cheaper PSU that will not be as efficient and would thus cost you more in electric costs and create more heat (which would again cost you more in AC bills and reduce server density). The active PFC supplies are
Except that I expect datacenters to have conditioned power, and so they can cheap out with the servers, with the same expectations. And I would expect consumer-grade systems to not have fancy power units, but ones that won't die on power irregularities from the electric co's. <snip> mark
