Volt-Amperes are definitely the normal measurement applied to explain the ability of UPS units. Using the equation above, we see which the bare minimum VA score we might want for our 400w needs could be a 640 VA rated program.
In all our many years of working with computers, the overwhelming majority of hardware failures is often directly attributed for the pressure components components encounter in the shut down and startup method (particularly when electric power surges or blackouts are concerned).
