I once blew out an APC by miswiring a switch on a computer (don't ask). I called tech support, they agreed that what I told them had happened shouldn't have happened, and shipped me a new UPS for free, without any hassle. From that point on, I swore I'd go APC first. > Do any of > these power supplies come with scripts to shutdown a Unix {or > Linux} computer?

Generally you need to add up your power requirements and match the load to the UPS's power rating. >I'll need one that can > interface thru the COM ports or the UBS port, if that is how > these devices work.
