Well, you probably can somehow power it up without a server connected to it? Active PFC tends to be simply a boost converter at the input stage that boosts the (rectified but still unfiltered) input voltage to (DC) 350 V or more, modulating the current to follow the mains voltage and should generally have no problem with DC input, especially so with wide-range inputs that have to be able to deal with different voltage levels anyway.

>modulating the current to follow the mains voltage and should generally have no problem with DC input I'm particularily worried about confusing that following/regulating circuity. If the 50/60Hz it senses are caused by screen refresh feeding back somehow, it might end up behaving "weird". But I guess I'll just try, and hope it won't break anything.
