Getting a little OT here, but how does one match up the VA ratings of the UPSs (and battery backups) with the power supply wattage ratings?
You can convert VA to watts with the following formula:
W = VA / sqrt(2)
Don't forget to give yourself a little wiggle room from there for short burst overages.
