Anyone have any thoughts on what would be the right sort of UPS for an Alienware Aurora R4? My understanding is that to calculate the (approx) VA required, you multiply the AMPS by VOLTAGE. The label on the back of the R4 says 7.9 Amps, and voltage is 230. Also allowing for 24" screen (1.5A) = 9.4 x 230 = 2162 VA.
Spec as follows: Core i7 3930k at 3.9GHz, 16GB Ram, 1 x GTX 660 (1.5GB), Creative sound card, Win7 64 bit, 24" Dell screen.
The PC wont be running at full load most likely almost all the time (do they ever?), so I have been looking at one of these: http://www.criticalpowersupplies.co.uk/idialog-ups-1600va-idg-1600
When the UPS cuts in it does not need to sustain the PC for that long, 5 minutes would most likely be ample. Long enough to turn electricity back on, and resume normal operations, or if electricity is not back, time to turn PC off.
Is there anyway to measure how much power the PC is typically using. I don't know what the efficiency rating is of the R4 power supply, but it is 875 watts.
Anyone else with an R4 have any experience of this?
Thanks in advance.
