@ Vicky: well, its NOPT about high rating UPSes, but its the thing with Active PFC rated PSUes and PURE/modified sine wave output UPSes
and since PURE SINE wave UPSes are available only in higher part of VA ratings, hence the reason.
But yes, a 500VA UPS will do gr8
I hope u knw wether ur PSU is an Active PFC type or no..
