HPE ProLiant DL380 Gen12 Power Supplies

Genuine HPE Flex Slot power supplies for the HPE ProLiant DL380 Gen12, new and refurbished. The platform runs one or two hot-plug PSUs in Platinum and Titanium efficiency grades from 800W to 2200W — two matching supplies give full 1+1 redundancy.

DL380 Gen12 Power Supply Specifications

• Family: HPE Flex Slot hot-plug, tool-less modules — single-output, 94–96% efficient
• AC options: 800W Platinum, 1000W Titanium, 1600W Platinum, and 1800W–2200W Titanium
• DC option: 1600W –48VDC, with a power lug kit or DC power cable kit for hard-wired installations
• Quantity: minimum 1, maximum 2; two matching PSUs provide 1+1 redundancy
• Rules: mixing two different power supplies is not allowed; 1600W units require high-line 200–240VAC

Match before you add. Mixing two different power supplies is not allowed on the DL380 Gen12 — both units must be the identical model — and 1600W-class units require 200–240VAC high-line power.

How many power supplies does the DL380 Gen12 need?

Production systems should run two supplies — hot-plug modules then let you replace a failed unit without downtime. Size the exact build with HPE Power Advisor: two 350W processors, 32 DIMMs, GPUs, and a full drive complement sit in a very different envelope than an entry build.

Choosing the Right DL380 Gen12 Power Supply

• Never mix models or wattages — both PSUs in the chassis must be identical.
• Check your feed: 800W and 1000W units accept standard ranges; 1600W-class units require 200–240VAC high-line power.
• Going DC: the –48VDC unit needs either the power lug kit or the DC power cable kit — plan the pair together.
• Refurbished PSUs are a low-risk buy — sealed, tested modules and a popular way to add redundancy affordably.

DL380 Gen12 Power Supplies FAQ

What power supplies does the HPE ProLiant DL380 Gen12 use?
HPE Flex Slot hot-plug PSUs: 800W Platinum, 1000W Titanium, 1600W Platinum, and 1800W-2200W Titanium AC units, plus a 1600W -48VDC option for DC power plants. The server runs one or two, always matching.

Can I mix different power supplies in the DL380 Gen12?
No - HPE states that mixing two different power supplies is not allowed. Both units must be the same model and wattage; when adding redundancy, buy the exact part number already installed.

Do the 1600W power supplies work on 110V power?
No - 1600W-class units require high-line 200-240VAC. If you only have low-line power available, use the 800W Platinum or 1000W Titanium units.

Can I hot-swap a failed DL380 Gen12 power supply?
Yes, provided two supplies are installed (1+1 redundancy) - pull the failed module and insert the replacement without shutting down. With a single PSU, schedule downtime for the swap.

Which power supply do I need for GPUs in the DL380 Gen12?
Plan high: GPU configurations also require the high-performance heat sink and GPU power cable kits, and push total draw toward the 1600W and 1800W-2200W Titanium units. Size the exact configuration with HPE Power Advisor before ordering.
