Hot-plug 550 W server power module

This Lenovo 4X20F28579 is a 550 W hot-plug power supply designed for compatible Lenovo servers. It installs as a plug-in module and carries 80 Plus Platinum efficiency certification. The unit measures 3.1 by 1.5 by 7.7 inches and weighs approximately 997.9 g.

Suited for hot-swap server bays.

This supply suits administrators who need to replace a failed unit without powering down the rack. Builders assembling workstations or tower servers that use fixed, non-hot-swap power supplies should look elsewhere.
