770W ATX Power Supply

This 770W ATX power supply delivers stable output for workstations and servers that require the PS-2771-1S-LF form factor. It is built for systems where the UCSC-PSU1-770W part number is specified and the unit has been tested working before shipment.

Capacity and headroom

The 770W rating provides headroom for multi-core processors, multiple drive arrays and add-in cards in compatible chassis. It runs out when a configuration demands more than 770W of combined continuous load or when the mechanical keying of the PS-2771-1S-LF does not match the target backplane.
