PC Peripherals Recommend a UPS for my high end video editing rig!

[Radon]

Suggest me a UPS. It should be able to give me 10-15 mins backup time (just enough time to shut my PC down)

My specs:

ASUS P8Z68-V PRO/Gen3

Intel i7 2600K

16 GB G.Skill Ripjaws X

Cooler Master 850W Silent Pro M

nVidia Quadro 4000

Corsair Force 120 GB SSD

2x1 TB Seagate HDD @ 7200 RPM (RAID0)

Dell U2711 Monitor
