Hi. OK, maybe this isn't fair, but I'm not really looking for a formula to pick out an uninterruptible power supply. I am hoping someone can suggest what I need.
I have an HP Proliant ML 100 G4 server with a Dual core Intel pentium processor 820, 1 GB of RAM, four WD 160 GB SATA non-hot plug hard drives with a DVD which probably won't be in use anyway.
I am guessing I will need a UPS with AVR or sinewave (don't know much about them). Also, can I used refurbished? I am on a budget.
