Dell HY105 670W Redundant Power Module

This Dell HY105 is a 670 watt redundant power module designed for the PowerEdge 1950 server. It supplies reliable power to keep the system running even if one module fails. The unit includes a single fan for cooling. It is sold new and ready for installation.

Fits PowerEdge 1950 Redundant Bays

This module suits administrators maintaining a PowerEdge 1950 that uses redundant power supplies. It is not for systems that lack a redundant power bay or that require a different form factor. Buyers needing a non-redundant unit or a higher wattage rating should look elsewhere.

670 Watt Capacity With Redundant Headroom

The 670 watt rating handles typical PowerEdge 1950 workloads with headroom for peak demand. In a redundant pair each module shares the load so the system stays online if one unit stops. It runs out of capacity if the server configuration draws more than the rated output.

Questions about this item

Does the HY105 redundant power supply fit the Dell PowerEdge 1950 server chassis?

Yes, the HY105 is designed specifically for the PowerEdge 1950 and slides into its redundant power supply bay.

Can I mix a new HY105 unit with an older power module already installed in the PowerEdge 1950?

The HY105 is a direct replacement; Dell redundant supplies are built to share load with identical modules in the same chassis.

How can I confirm the HY105 is operating correctly once installed?

The PowerEdge 1950 front panel LEDs show green for each supply when both modules deliver power and the fan spins normally.
