Lenovo HE 48VDC 750W Power Supply

The Lenovo 94Y7631 is a DC power supply module that delivers up to 750 watts and installs as a plug in unit for select Lenovo System x servers. It operates on a -48 volt input, aligning with telecom grade power systems and providing clean, stable energy for demanding workloads.

Designed for environments where downtime is not an option, the module supports hot plug operation. Administrators can swap or add a unit while the server stays online, which streamlines maintenance and protects service level agreements. When paired with another identical module, it forms a redundant pair that balances the load and keeps applications running if one supply is removed or experiences a fault.

The 94Y7631 fits directly into servers such as the System x3550 M4, x3650 M4, and x3650 M4 HD. The lock in mechanism works without tools, so technicians can complete installations quickly in tight rack spaces. Once in place, the high efficiency design helps control power costs and reduces heat, two factors that matter in dense data centers.

This supply is a sensible choice for IT teams that manage virtualized clusters, web hosting farms, or branch office hardware that cannot afford unexpected outages. By matching Lenovo hardware with a Lenovo engineered power source, you keep compatibility simple and support streamlined.
