FSP EP 1000 UPS review - Why need an UPS these days?

  • Published in Case/ PSU reviews

Testing

There are multiple ways to test an UPS, but for the more advanced methodology I don't have the optimum tools to get reliable results. instead, I am going for the end-user approach. As such, I prepared a test system designed to pull out 87Watt in idle, 365Watt whilst running the Prime95 benchmark, 534Watt while running the Furmark benchmark, and then to make sure smoke comes out of the machine, both running simultaneously, drawing out 687Watts.

Battery Charge

I discharged the battery in two different ways. The first was discharging the UPS at a load of 100% to auto-off (600W), whilst the second was at only 50% load (300W) and then steadily decreasing the discharge until the battery was empty.

To bring it back up after the full discharge took a lot more than what was written on paper. It took about 28 hours, with the current past the first six-hours dropping from 1000mA to a measly 50mA and a voltage of 13.7V. However, bringing the battery to about 90% capacity took only 2-hours, and the current was a lot lower on average, resting at about 180mA.

Why are these figures important? Because battery-charging parameters affect the battery life, and as such, the UPS itself in the long run.

Battery Run-Time

With a system running 687W in full-load, the 600W UPS couldn't sustain it for a lengthy amount of time.
