The "smart" UPS has a cable running from a USB port and it signals the computer (running a UPS daemon) to power down after a certain period of time or after the charge in the UPS has got to some user set percentage. The "thick" UPS doesn't have the cable and just runs your hardware until the battery is flat or the power returns, whichever comes first. As you will have guessed, the "smart" UPSes are more expensive than the "thick" ones and they also tend to be beefier. Obviously the "smart" ones are more featureful but you know what your budget is. I've got an APC Smart 750VA which powers my server, router and workstation. I've also got a trailing lead plugged into it. This I use to plug in miscellaneous electrical gadgets and protect them from surges. Current load: 37% of full capacity. I run apcupsd from ports and it seems to work well. So my recommendation is to get something like mine (if you can afford it) and you can plug in other stuff and still have a reasonably long runtime. PS. They have lead acid batteries and it's best not to flatten them. Regards, -- Frank Contact info: http://www.shute.org.uk/misc/contact.html
