What UPS to buy for my Desktop Alienware Aurora R5 (2016)

Hello all,

I just bought an Alienware Aurora R5 and I would like to know your advice regarding which UPS should I get. In case there is a blackout in my area while I'm gaming or using my computer, I would like to have enough time in order to shut down the computer properly and avoid any kind of damage.

These are the specs and devices connected to my computer:

-850W PSU Liquid Cooled Chassis

-Dual NVIDIA(R) GeForce(R) GTX 1080 with 8GB GDDR5X each (NVIDIA SLI(R) Enabled)

-64GB (4X16GB) DDR4 2133MHz SDRAM Memory

-1TB PCIe SSD (Boot) + 2TB 7200RPM SATA 6Gb/s (Storage)

-Tray-Loading Dual Layer Blu-Ray Reader

-Dell Wireless 1820 Card (802.11AC Dual-Band Wi-Fi + Bluetooth 4.1)

-Intel(R) Core(TM) i7-6700K Processor (4-Cores, 8MB Cache, Turbo Boost 2.0, Overclocked up to 4.2GHz on all four cores).

-Dell 24" S2417DG Gaming Monitor

-Acer 23" H236HL LCD Monitor

-1 USB port hub

I was thinking in getting CP1500PFCLCD 1500VA/900W but Im not really sure if this is good enough for my gaming rig?

Your help and advice regarding which UPS do I need will be highly appreciated.

Thanks,
