UCSC-PSU1-770W is a 770W AC internal power supply for UCS C220 M5, UCS C240 M5 and UCS C245 M6 rack servers, with hot-swap service in redundant 1+1 power bays. It accepts 90-132V AC or 180-264V AC input and provides 12 VDC output for RSP2 C-Series server bays. A Cisco UCS C220 M5 power supply order must match the installed wattage and input type because two-supply servers require identical supplies. UCS C220 M5 serviceable locations put the power supplies in rear bays, and a live replacement is supported only when the second supply is present. The same RSP2 form factor spans those C-Series hosts. UCSC-PSU1-1050W is the higher-wattage AC sibling for configurations that need more headroom.

9.5A at 100V AC and 4.5A at 208V AC set the branch-circuit check before the server goes back in the rack. 47-63 Hz input keeps the module inside standard single-phase AC ranges, and 15A sub-cycle inrush sets the upstream breaker check. Maximum input is 950 VA at 100V AC for power strip capacity checks. 12 ms hold-up time at 770W keeps output within regulation during an input dropout. Climate Savers Platinum Efficiency and 80Plus Platinum certification put UCSC-PSU1-770W in the Platinum filter for C-Series server power. IEC320 C14 input takes C13 cords, and CAB-9K12A-NA supplies 125V, 13A North America service where that cord is selected. C-Series server regulatory coverage includes UL 60950-1, IEC 60950-1, FCC 47 CFR Part 15 Class A, CISPR32 Class A and EN55032 Class A.
UCSC-PSU1-770W is available new sealed or certified refurbished. Certified refurbished units are inspected and bench-tested in a compatible host or on a load tester; output holds rated voltage under load, status LEDs report normal, and hot insertion and removal are verified in a live host. Order the same wattage and input type already installed. New units carry up to a 3-year extended warranty, certified refurbished units carry up to 1 year, and returns are 30 days on every condition; terms apply. Regional stock and RMA with advance replacement cover UK, EU, US and MEA sites, with PO accepted and Net-30 for government.

A failed UCS C220 M5 or UCS C240 M5 rear-bay power module needs the same 770W AC RSP2 form factor. Specify UCSC-PSU1-770W when the chassis label or inventory shows 770W AC, then match the second bay before the PO.
A single-supply C-Series server can take a second identical module for 1+1 redundancy. Use UCSC-PSU1-770W only when the installed unit is the same PID or the same 770W AC RSP2 supply, and confirm two cords before the PO.
A C-Series rack spares pool can cover UCS C220 M5, UCS C240 M5, UCS C245 M6, CMX 3375 and APIC-EM DN2-HW-APL hardware that carries the 770W AC supply. Separate AC and DC spares, then mark each unit by wattage and input type before the PO.
-48V DC sites
UCSC-PSU1-770W is an AC module and does not take -48V DC input. Order UCSC-PSUV2-1050DC for a C-Series -48V DC bay.
Mixed wattage pairs
C-Series two-supply servers require identical power supply types and wattages. Use UCSC-PSU1-770W only beside another 770W AC unit, not UCSC-PSU1-1050W.
1600W AC builds
UCSC-PSU1-770W is below the 1600W AC option for C220 M5 and C240 M5 servers. Order UCSC-PSU1-1600W for high-line AC configurations.

UCSC-PSU1-770W fits UCS C220 M5, UCS C240 M5 and UCS C245 M6 rack servers with RSP2 power bays. CMX 3375 and APIC-EM DN2-HW-APL appliances use the same UCS 770W AC rack-server supply. Two-supply C-Series servers require identical power supply type and wattage.
UCS C220 M5 uses UCSC-PSU1-770W, UCSC-PSU1-1050W, UCSC-PSUV2-1050DC, UCSC-PSU1-1600W and UCSC-PSU1-1050ELV power supply options. The 770W AC module is the lowest AC option in that group. A second supply must match the first unit’s type and wattage.
UCSC-PSU1-770W is rated at 770W with 12 VDC output, 90-132V AC or 180-264V AC allowed input ranges, and 47-63 Hz frequency. Maximum current is 9.5A at 100V AC or 4.5A at 208V AC. Hold-up time is 12 ms at 770W.
Yes, UCSC-PSU1-770W is hot-swappable when two power supplies are installed redundantly as 1+1. A one-supply server must be shut down and removed from power before the module is pulled. Redundant hosts allow AC supply replacement without shutting down the server.
UCSC-PSU1-770W has a maximum AC input current of 9.5A at 100V AC and 4.5A at 208V AC. Maximum input volt-amperes is 950 VA at 100V AC. Use those values for branch circuit and rack PDU capacity checks.
UCSC-PSU1-770W uses an IEC320 C14 input and takes supported C13 power cords. CAB-9K12A-NA is the 125V, 13A North America cord option for C220 M5 servers. CAB-C13-C14-2M is a 250V, 10A C13-to-C14 cabinet jumper option.
No, UCSC-PSU1-770W must not mix with different wattages in two-supply C-Series servers. Both installed power supplies must be identical in type and wattage. Use a second 770W AC unit beside it, or replace the pair with the target wattage.
UCSC-PSU1-1050W is the higher-wattage AC option; UCSC-PSU1-770W is the 770W AC option. The 1050W unit delivers 800W at 100-120V AC and 1050W at 200-240V AC. Choose 770W for a matching 770W bay and 1050W for a matched higher-output pair.
UCSC-PSUV2-1050DC is the -48V DC option; UCSC-PSU1-770W is the AC option. The DC unit uses a fixed 3-wire block and delivers 1050W on 12 VDC main power. Choose AC for line-voltage racks and DC for -48V plant power.
UCSC-PSU1-1600W is a high-line AC option; UCSC-PSU1-770W works across 100-120V AC and 200-240V AC nominal ranges. The 1600W unit delivers 1600W at 200-240V AC only. Choose 770W for lower AC branch circuits and 1600W for matched high-line server builds.
Cisco stopped selling UCSC-PSU1-770W on September 22, 2026. No migration product is available for this PID. UCS C220 M5, UCS C240 M5 and UCS C245 M6 hosts that remain in service need matching 770W AC bay stock.
