Lenovo Redundant Power Supply 750W
This Lenovo redundant power supply delivers 750W of output for compatible server chassis. It supports both 230V and 115V AC input ranges for flexible deployment. The unit is designed as a hot-swap module to maintain uptime during maintenance. It suits IT environments requiring continuous power availability.
Replaces failed or ageing hot-swap PSU modules
Swapping a degraded unit for this model restores full redundancy without powering down the host system. The upgrade is worth it when an existing supply shows fan noise, voltage drift or has reached its rated service life. It eliminates the single point of failure in a dual-PSU configuration. Compatibility must be verified against the server's qualified vendor list.
750W capacity with dual-voltage input headroom
The 750W rating comfortably handles typical dual-socket server loads with multiple drives and PCIe cards. Headroom remains adequate for moderate GPU or accelerator additions within the chassis power budget. It runs out when the combined draw exceeds 750W or when the chassis requires a higher-wattage redundant module. Always confirm the exact power budget for the target platform.

Questions about this item
What chassis slot width does the 4P57A26291 module occupy?
The module is a hot-plug redundant unit designed for Lenovo server bays; it slides into a single power supply slot from the rear.
Which cable must be seated first during installation to avoid a no-power condition?
Insert the module fully until the latch clicks, then connect the AC cord to the 115V or 230V inlet; the supply will not start if the cord is attached before the module is locked.
How many hot-swap cycles are the internal fan and electrolytic capacitors rated for before replacement?
The fan and capacitors are built for continuous operation in redundant mode; swap the entire module when the front LED shows a fault rather than servicing individual parts.
