Choosing UPS

post #1 of 3
Thread Starter 
I'm looking to buy a ups/surge protector from APC and I was wondering how big of a model I would need...My PSU is a sunbeamtech 550W psu.....now I want the ups to have enough power to run my computer for around 20 minutes, giving me time to shut down my computer if possible, otherwise the ups will take care of it......so what rating should I look for in a ups for my computer? 550W or more? or would 300W or 350W suffice?

Be careful. I bought APC which is an excellent choice but the numbers are
misleading. I suggest you go as high as you can afford. A little extra won't
hurt. Also the more powerful models include automatic power conditioning (all
the time, it never dips into your back-up battery like the lower powered models)
and the higher powered models also provide better wattage monitoring software.
I have a UPS 750 and wish I had purchased just a bit higher - actually what happened
is I bought the wrong model by mistake. I plan to upgrade as soon as I can afford
it.

So far though - I haven't regretted my purchase one bit. Plenty of times when
my UPS has stopped power surges and tided me over in power outages. I fold
24/7 and this guarantees a steady power supply.

Yup, go for the highest VA rating you can afford,

I have a Unitech 1650VA UPS, it gives out 800ish watts and will shut the computer down for you after the twenty mins via USB connection.

going for a higher rating will give you room for expansion later.
dont go for an equal to your PSU rating, you want to run your monitor of it aswell!!!! no good having the computer on for 20mins if ya cant see wots going on!!
Good luck!
