is ur SMPS (Power supply) an Active PFC type..???? if yes then go in with a UPS (i wud also recommend u APC) with a PURE SINE WAVE based UPS... :)

the "SMART UPS" Range of APC UPS are pure sine wave UPS.. :)

whereas, "BACK UPS" Range of APC UPS are stepped (Modified) SIne wave) UPS (Wich u shud buy if u hv a SMPS which is a PASSIVE PFC type) :)

Alternatively, use this tool (from APC india website) to help u select a proper UPS wattage :) -----> UPS Selector Sizing Applications

hmmm..... well, u 1st and foremost need to tell me (if u knw exactly) wether u hv an ACTIVE PFC type of SMPS or a PASSIVE PFC type... smps... coz see, the simple understanding (In general) is this...

1.) IF.... u hv an ACTIVE PFC type of SMPS then go for ----> PURE SINE WAVE based UPS (Wich in APC's case) wud be the SMART UPS range of UPS (not BACK UPS range) :)

2.) IF... u hv a PASSIVE PFC type of SMPS then go for ----> STEPPED/MODIFIED SINE WAVE based UPS (Wich in APC's case) wud be the BACK UPS range of UPS (not SMART UPS range) :)

so check ur SMPS manual and then letme know... :)
