An active-PFC label and sufficient UPS watts do not establish a reliable UPS\u2013power-supply pairing.<\/strong> Check the UPS output in each operating mode against the exact power supply\u2019s input requirements, then verify the DC load through startup, transfer, battery operation and return to mains. Release the combination against equipment-level voltage and functional limits.<\/p>\n

For an OEM, the question is whether its assembled equipment continues the required function when AC conditions change. A UPS that supports the average load can still require additional evidence for starting or transferring that load. Conversely, PFC alone is insufficient reason to reject a pairing without checking its documented conditions.<\/p>\n
