Smoth: in addition to what Amir suggested, if you have powerboards already with some form of protection, you might as well use them too. They won't hurt.
We don't have the meter surge arrestors here (Australia, where I am a qualified electrician), so if that is not a possibility, consider a 2 pole unit in the sub switchboard in your apartment. One pole in A-E and one N-E. Get the largest rated and approved device you can and get it installed to the current NEC rules by an appropriate qualified person.
For the UPS, buy a known reputable brand such as Eaton. They aren't much more expensive. For UPS capacity, if it's mainly the PC, go to one of the PSU manufacturer sites and use the PSU calculator. Here is Coolermasters
. This will be a worst case with everything running at max, but use it as it will give you a bit of capacity to spare. Add in your monitor(s) power consumption and anything else you need
to run off the UPS, eg cable modem. Specs will be in the manuals or spec sheets. Total them up and choose the model closest to your needs. If different manufacturers give ratings in W and some in VA, they will be close enough in this application to be considered the same.
