What is VA vs Watts: UPS Sizing Guide about?

VA and watts measure different aspects of power consumption - VA measures apparent power while watts measure real power consumed. For equipment with power factor correction, watts and VA are equal, but otherwise watts are typically 60% of VA.

To avoid overloading the UPS, size loads to less than 60% of the UPS VA rating unless you know the exact watt ratings. Contact Power Solutions for help properly sizing a UPS
