What UPS should I choose for my PC

[PYROMASTER300]

I live in an area where the power grid is not very stable and always fluctuates a lot. So much so that when bad weather came through, the power fluctuation broke my computers PSU. My house does have a generator, but it takes about a minute to start and by then the power is already out, nor does it protect from momentary power drops or spikes. I was told that I need to get an interrupting power source, but I don't know what will work for my computer because my computer is a little more power hungry then most people's computers. Can anyone help me find the right UPS for my computer?

I only need something that will last long enough for the generator to start and to prevent power spikes from damaging my computer.
