Production systems should run two supplies — the internal view shows up to two hot-plug redundant Flex Slot supplies, so a failed module can be swapped without downtime. Size the exact build with HPE Power Advisor, which the QuickSpecs recommend running before any power supply selection.
Choosing the Right DL345 Gen11 Power Supply
- Never mix wattages or models — all power supplies in the server should match, so when adding the second unit, order the exact part number already installed.
- Check your feed: the 1600W units only support 200VAC to 240VAC high line voltage.
- Size against the real build, not the chassis — processor cTDP runs from 125W to 400W here, and the drive and DIMM count move the number as well.
- Refurbished PSUs are a low-risk buy — sealed, tested hot-plug modules, and the usual way to add the second supply affordably.
