Actually I should add, don't opt for an online UPS unless you want to clear your bank account.
That APC should do you good, if your computer power supply has at least a hold-time of 10ms or higher and supports PFC. The advantages of that APC is lower cost compare to online UPS, lower heat because of minimum components and high reliability because of lower operating temperatures. However the disadvantages is if you live in an area where the AC power fluctuates a lot and is unstable, your line-interactive UPS will wear out its battery quickly because it will have to constantly switch over to the battery each time it experience a brownout, and to much of that will drain the battery which will leave you with barely to none power when the real blackout occurs. Also because of the switching to battery, you should check the switch or transfer time of your UPS and compare it to your computer power supply hold-time. If the UPS switch time is lower than the PSU's hold-time then it should be good.
This is a good factor to know when buying inexpensive offline UPS also, which might save you some money in the long run. As far as I know, APC don't make anymore offline UPS. But some company probably still do.
