HPE 750W CS Power Supply for ProLiant Servers

The HPE 674890-001 CS is a 750W plug-in module rated at 94 percent efficiency, designed for Hewlett Packard Enterprise rack and tower platforms. It delivers 750 W of output power from a 277 V AC input and fits the common ProLiant form factor used across multiple generations.

Suited for ProLiant DL

This supply matches the exact part number listed for DL360p Gen8, DL180 G6 and numerous FlexSystem R390 configurations. Builders assembling custom chassis, desktop workstations or non-HPE racks should look elsewhere because the connector layout and firmware handshake are proprietary.

94 percent efficiency at 750 W output

The headline specification is the 94 percent efficiency rating at the full 750 W load, which determines thermal load and operating cost in dense server rows. If your chassis requires a different wattage, voltage range or form factor, this module will not meet the requirement.

Questions about this item

What does the 94 % efficiency rating mean for day-to-day power draw?

At typical loads the unit converts roughly 94 % of input power to output, so less energy is lost as heat and the server draws less from the mains.

What input voltage does the 277 VAC rating cap in practice?

The supply is rated for 277 VAC input, so it will operate on high-voltage rack circuits up to that level.

What chassis space does the plug-in module form factor need?

It fits a standard hot-plug power-supply bay in the compatible ProLiant and FlexServer models listed.
