    yeah a ups wasnt in my budget i had it on a $ surge protector but lightning hit the house and took it out so kinda sucks also i think the psu had something to do with it.

    Surge protector strips are virtually useless; a UPS provides true surge protection. APC is one of the best in the business.

    The UPS unit I have now, an APC brand, is ok but the battery is nowhere close to being able to power my computer when the power is lost. This is lousy but it still protects the computer from being damaged during a power surge, so I'm grateful to have it. You can hear the breaker when there is a spike, and then it resets after the power levels return to normal. While it does this, nothing happens with the computer even if it's running.

    The power ratings should be chosen carefully; some PSUs have current input needs that are higher than what most UPSs can provide. Most people look at the wattage (i.e. real power) only; the apparent power ratings also need to be taken into account IMO.

    In order for my computer to be fully covered, I would probably need to invest in one of the high-end Ultra solutions. My PSU is 1000w but I'm not sure what the current input requirements are. Where can I find out? It's an Ultra X3 1000w modular. I would love to have a UPS capable of running my computer when the power goes down (happens a lot up here) but the premium solutions are in the $200 range.

    The input current requirement for your PSU is 8A RMS, which translates to about 11.3A peak.

    You can see it here.

    For choosing a suitable UPS, you would need to know the peak power draw of your PSU, and choose a UPS with the appropriate current output and wattage ratings.

    Alright thanks, I'm gonna do a little shopping a bit later and see what I can come up with.

    That is an excellent unit, but overkill for a PC. It is meant for running motors; true sine-wave output and a high apparent power output are needed for these.

    rage can you recommend a good unit for me?

    I recommend this unit and this one, as excellent choices. The APC is, of course, the better buy.

    I was looking at those same units on Newegg yesterday... but then I decided to order a PS3 :haha:

    I'm still not sure which UPS would be able to run my system... but I think that APC BR1200 would. The only problem is it would probably only be able to run the computer, and nothing else if I were to use power. That's not ideal but it would work I guess. Even if it was only able to run the computer for 10-15 minutes I would be happy... that's plenty of time to get my work saved and to shut down properly.
