Buying a UPS for my computer (need advice)

[Yankey]

I am no expert when it comes to electricity,and where I live (Lebanon) the electricity is really unstable and I am worried about my pc so I think it's time to get me a backup UPS

my pc specs are the following:

GPU: R9 270X
CPU: i5 4670k

PSU : Thermaltake Smart SE 630W

PSU Details

I found a couple of UPS's that I think would be decent,but I might be totally wrong.

E&B 1200VA

PCE M8 1500VA
PCE M8 details from their official website
Are these good ones by any chance? and which one sounds like the better choice? If both are bad then what should I be looking for? I found the price on these really decent aswell,and I just want to make sure I can sustain a few minutes on my PC incase the electricity goes off then back on again.

Thank you in advance!

Whats your price range ?
Few minutes under what load ?
Under full load your Video can go to 250-270W usage and the CPU can go max to 95-100 Which is around 350-360 watts add some other consumption and you will probably need something that can power up 400 watts.
Most of the UPS's have diagrams that show how much they can sustain under what usage.
At my work, we are using Eaton & APC mainly.
So far i am happy with them, easy to setup, easy to change batteries.

My budget is up to a $100,and yes I probably need something that could sustain around 400-450 watts just to be on the safe side.Here are the other options I have available

PCE M8 1500VA says 600w, prolly around 1min under full power or 0.7 mins.
Which means @half power it should be 7mins.
And around 400w should be at least 2-3mins.
Cant see anything about warranty, is there any ?
Network/Tel/Modem/Fax spike protection* is optional, not sure what that means.
Those are 220V input UPS's, whats your standard ?
No self-battery test, not sure if software provides any information.
Battery Type & Number - 12V/7AH x 2 Those should be standard batteries.
Not sure how does warranty cover batteries.

If PCE M8 does have warranty, for at least 1 year, it would be the best.
Even on their site, i couldn't find chart that shows run time under load.
Warranty should include batteries, because if they have been in warehouse a lot of time, they may fail sooner than expected.
