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.

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.
It's a hot-swappable 300-1897 (aka X6328A aka Type A217) 1050W Sun PSU. I'm primarily worried about the active PFC I expect in it.
Is there a way to test such a PSU without risking the entire server? (save for taking everything out that isn't needed to post into BIOS)
