Buy surge protection, ups or keep weird thing I got.

So I lost a PSU for who knows what, I had a corsair 850w, which i bought nearly two years ago, and out of nowhere it started to shut down. Each time more frequently. until each time I started it it would shut down inmediatly as soon as windows load screen would be done. I tried another smaller psu, and my pc worked out just fine.

Why did it got damage I dont know, but I dont want it to happen again and a power surge may have been the cause.

I have this. I honestly dont know whats its purpose. I bought it like 4 years ago, and I was a little too young to be informed...and it costed me less than $20. Is it a power surge? I got a computer with a 850w psu, is it a good idea to have this as protection?

To me seems like a phony power surge supressor.

Now to replace it. http://www.amazon.com/Belkin-BE112230-08-12-Outlet-Protector-Protection/dp/B000J2EN4S/ref=sr_1_3?ie=UTF8&qid=1333047420&sr=8-3

Shoild I get one of those?

I read that for rural areas such as mine, sometimes a UPS is a better choice. There are no common blackouts but I heard that a UPS can protect a computer from lower ranges of voltage which are also harmful, and a power surge is useless against those.

Thoughts? http://www.amazon.com/CyberPower-CP425SLG-UPS-Standby-Green/dp/B0030SL08A/ref=sr_1_4?s=electronics&ie=UTF8&qid=1333047579&sr=1-4

It seems like that one can only take 225w. Can I use that one, not mind about having my pc shut down on a black out and use it for better protection? Its battery might not be potent enough to keep my pc running, but it may prevent damage I guess.

Thanks a lot in advance.
