Re: UPS recommendations

The first factor is load size--how much you plan to power with it, you have to get a unit that is sufficient--thus the VA rating. The next biggest factor most people consider is load time--which is just running the math against the battery size and your equipment power requirements. Bigger batteri

Re: UPS recommendations

Just perusing amazon, looks like your options for non-APC brands are Tripp Lite or CyberPower. Both have units that are big enough for your server priced under $100. I can't say as to their safety, quality, or software availability. /* PLUG: http://plug.org, #utah on irc.freenode.net Unsubscribe:

I've owned several different UPS brands over the years and APC was the worst by far. My two APC units both failed within two years of purchase. The best UPS units that I've owned have been a pair of Exide Powerware Prestige EXT (1500VA)

I've used APC for years--since I obtained several off lease years ago for almost nothing. However, they've all slowly bit the dust--their charging circuits giving out. Some research reveals that APC has always had a poor design--the electronics are not insulated from the heat making component failu
