The transformer inside getting that hot that you don`t like to touch it and i think 15W out of 50 is a little bit high and that inside a plastic case looks a little bit dangerous to me, too.  since this ups is old anyway, i`d like to replace it with a better one.

While I'm no expert on the subject, I'm quite pleased with my CyberPower
"Intelligent Series" 1500LCD. That's a line-interactive job, that
currently powers two ITX-based servers, a 24port gigabit switch and my
3640 router with no problems whatsoever.
