Will this ups work?

At the moment my rig draws between 600 and 700 watts. Once I have a ups sorted I will be adding a second msi gtx 1080 sea hawk and the rig will then draw around 900 watts.

I have had problems with power supplies over the last 18 months (3 Corsiar AX1200i psu's have died on me) and so I am looking at getting a ups to help protect everything. I think the power from the wall here is awful and that is causing the issues.

The ups I am looking at is a 1200va one, I have had a look around online and the conversion of va to w seems to vary, so I am not sure if this ups is going to work.

This is the one on Overclockers.co.uk :

The specs :

  • 1200 VA sealed LA battery technology
  • Supports 110/120 or 220/230/240 volts @ 50/60Hz
  • Simulated sine wave to protects against spikes, brown outs etc
  • Battery back-up time approx. 45 minutes*
  • Intelligent USB interface for monitoring and OS shutdown
  • Supports Windows(tm)98/2000/2003/XP/Vista
  • Supports Windows(tm)7 and Windows8(tm)
  • Short circuit and over discharge battery protection
  • Cold-start with automatic battery charging + RJ11 filtering
  • 4 IEC (female) output connections for standard device input
  • Status LEDs and control for battery, backup and charging
  • Dimensions 95mm (W) x 340mm (D) x 165mm (H) approx.

The ups with postage is just under £100, but my budget for a ups is £150 ish

If this one will work and help to protect my system great, if there is something else that I should look for to help protect it I would love to know or if there are any specific features I should be looking for to safe guard my rig and stop another psu going bad.

Thanks

Not worried about how long it will last in a power cut. Just wanted to check it will output enough to run my rig.

I want it just as a safe guard against dodgy power from my outlet

Just the rig. It is the only thing that I have had an issue with.

The monitors, printer and network switch are all just in surge protectors
