Just setting up a new machine, and looking at UPSes to protect it. The one issue that I am wondering about is that companies like APC convert their VA ratings to Watts using a rather large power factor (ie 650VA converted to ~400watts). I assume this is just them trying to sell more of their bigger units, as I can't see anything in the computer or the power supply that would cause much of a problem with PFs. I mean there will be a few fan motors cooling the box, but we aren't talking industrial equipment here.
Of course I can figure out the real factor once I get the machine, however it is easier to get the UPS with the machine. My current machines are laptops, so that won't do me much good. I'm setting up a Dual Athlon rig with a 460watt PS and a 21" Sony that is rated at about 150watts (not that I'm going to do it, but lets assume its all running at full load). So basically, for anyone who knows - what would be a realistic PF to provide sufficient headroom for computer rigs? I might still go for the 1000VA units just to get more run time, but I'd like to know what I really need before I buy ;P
Thanks in Advance,
