PS 340W — Cross-Brand Comparison

About PS 340W

Server power supplies are precisely engineered for chassis-specific connector layouts, voltage rails, and hot-swap signaling. The PS 340W is a wattage-specific PSU module; this page lists it for HPE and IBM, each under its own OEM part numbers.

Cross-referencing guidance

When cross-referencing a PSU between brands, verify three things: (1) physical connector layout (Dell uses proprietary keyed connectors that differ from HPE Flex Slot and Lenovo Common Slot designs), (2) signal protocol (most modern OEMs use PMBus 1.2 with vendor-specific extensions), (3) firmware handshake (the BMC validates the PSU at power-on — incorrect firmware triggers a no-power fault). ICD matches the part number to the target server and confirms compatibility on the quote.
