1100 W Redundant Power Supply

This unit is a 1100 watt redundant power supply built for Dell PowerEdge servers. It delivers up to 89.6 A on the +12 V rail and 2.0 A on the +12 V standby rail. The supply accepts 100-240 V input at 50/60 Hz with a maximum AC current of 12-6.7 A. A single fan provides internal cooling.

Suitable for PowerEdge R510 R715 R810 R815 R910 T710

This supply fits the listed Dell PowerEdge models and supports hot-swap redundancy in those chassis. It is not for systems outside this compatibility list or for builds that require a different form factor or output configuration. Buyers needing non-redundant desktop units or different voltage rails should look elsewhere.

1100 W capacity with 89.6 A on +12 V

The 1100 W rating comfortably handles dual-processor configurations with multiple drives and expansion cards in supported servers. Headroom decreases when both CPU sockets are heavily loaded alongside full drive bays and PCIe cards. The single fan may limit sustained output in high ambient temperatures.

The unit is listed for PowerEdge R510, R715, R810, R815, R910 and T710 systems.

Can I mix this 1100 W unit with the original lower-wattage supply already in my PowerEdge?

Redundant operation requires matching wattage; install a second L1100A-S0 for full redundancy.

What front-panel indication confirms the L1100A-S0 is delivering power after installation?

A steady green LED on the supply face shows normal +12 V and +12 Vsb output.
