How's this for a cheap ups

really cheap refurb UPS

I want a really cheap battery backup. This UPS goes for a little under my PSU's maximum wattage (550).

I wouldn't plug anything in it except my PSU. What do you think? Not sure if its reccomendable, but is it worthwhile for such cheapness?

personally, i would never buy a referb ups. especially since i dont know the exact condition of it. they may say that it works, but for how long? will the thing explode and kill all my data? these are things you need to ask before buying something so critical for your machine.

That looks like an old product from the Line-R series. That would make it a line conditioner not really a UPS.
