couple of PSU and UPS questions
what does PFC (power factor correction) do exactly?
and also, say I have a 560W psu . . . if i have components that only make up about 420W, will the power supply do 560w or 420w? or somewhere in the middle (efficiency and stuff)?
also, if i have probably around 420w of components, what kind of UPS power battery thingy should i get for it? i just need about 2 minutes worth of battery to properly shut down (you know, make sure hard drives can finish their stuff)
i think i would just plug the computer into that, not the monitor and speakers and printer and stuff
