Designed for Lenovo B300 servers

This 1050 watt server power supply carries part number DPS-1000DB A D73299-007. It is built to fit the Lenovo B300 platform and delivers the rated output for that system. The unit is supplied new and matches the original equipment specification. Builders working on other chassis or needing a different form factor should look elsewhere.

Direct replacement for the OEM unit

Installing this supply restores the power capacity the server was designed for without adapter cables or firmware changes. The connector layout and mounting points align with the factory unit so the swap is straightforward. No additional accessories or software are included in the package. Servers that require redundant or hot-swap modules will need a different configuration.

Questions about this item

How often will the DPS-1000DB A fan need replacement in a Lenovo B300?

The internal fan is the primary moving part; under continuous server duty it should be inspected at each scheduled chassis service interval and replaced if bearing noise or speed variance appears.

What limits sustained output first on the DPS-1000DB A?

The 1050 W rating is the hard ceiling; thermal protection will throttle or shut down the unit before any other component reaches its limit.
