UPS power requirement. Suggestions?

[HassanRashid]

Hi,
I'm currently running an i7 4790 on a Z97 HD3 and R9 280x Sapphire vapor. All of this is running on corsair TX850. I need an UPS setup which would maybe give me 10-15 minutes backup.

So I need your suggestions on the power requirement etc and brands! Would be a lot of help if I would get quick replies as I will probably go check out the market tomorrow

I'm currently a little short on cash so I was looking for something more around the 100 bucks side.

the question is will it last 15 min while working on your computer since your system at full load could pull as much as 500W.

the main purpose of a UPS is to give you enough time to save your work and shutdown your system not to keep working though a power outage.
