Hi, I have a noobish question here.. my new place is having lots of power outages lately. I'm pretty sure my pc don't really appreciate that. Hence, i'm planning to buy an UPS for my rig.

Using the extremepowersupply calculator, my rig generates about 240w at 90% load and 153w at 60% load. Most of the time, if the rig is unattended, it usually stays idle @ less than 10% load (mostly getting some stuff from the newsgroup). My PSU is Silverstone ST56F

So, would it be sufficient for me to get the APC 650VA http://www.apc.com/resource/include/...S&tab=Software for about RM 350 ~ USD 110? Or would it be an overkill, whereby I can consider cheaper brands such as koss etc.? Thanks in advance!
