HPE ProLiant DL385 Gen11 Power Supplies
Genuine HPE Flex Slot power supplies for the HPE ProLiant DL385 Gen11, new and refurbished. The platform runs one or two hot-plug PSUs as standard — two matching supplies give full 1+1 redundancy with tool-less replacement, and the Power Distribution Board kit takes the count to four.
DL385 Gen11 Power Supply Specifications
- Family: HPE Flex Slot hot-plug, tool-less modules with C-14 inlets that support HPE Power Discovery Services
- AC options: 800W Platinum (94% efficient), 1000W Titanium (96%), 1600W Platinum Low Halogen (94%), and 1800W-2200W Titanium (96%)
- DC option: 1600W Flex Slot -48VDC, which also requires the DC power lug kit
- Quantity: one or two as standard; four with the Power Distribution Board kit, which cannot be configured on the 8SFF or 8LFF CTO server
- Line voltage: the 800W and 1000W units accept 100–240VAC; the 1600W Platinum and the 1800W-2200W Titanium require high-line 200–240VAC
- Rules: mixing different power supply SKUs is not allowed, the one exception being a four-supply build that includes the 1800W-2200W Titanium
Match the part number, then check your feed. Mixing different power supply SKUs is not allowed, so buy the exact model already installed. The 1600W Platinum and 1800W-2200W Titanium units are high-line only at 200–240VAC; the 800W and 1000W units accept 100–240VAC.
How many power supplies does the DL385 Gen11 need?
| Configuration | PSUs | Typical choice |
|---|---|---|
| Light build: 1 CPU, few drives | 2 (1+1 redundant) | 800W Platinum |
| General-purpose 2P build | 2 (1+1 redundant) | 1000W Titanium |
| Loaded: 400W EPYC pair, 24 DIMMs, dense NVMe | 2 (1+1 redundant) | 1600W Platinum |
| GPU or 48SFF chassis with accelerators | 4 (Power Distribution Board kit) | 1800W-2200W Titanium |
Production systems should run at least two supplies — hot-plug modules then let you replace a failed unit without downtime. Size the exact build with HPE Power Advisor, because a 400W processor pair, 24 DIMMs, and accelerators move the number a long way.
Choosing the Right DL385 Gen11 Power Supply
- Never mix wattages or models — HPE does not allow mixing power supply SKUs, so match the exact part number already installed. Only a four-supply build including the 1800W-2200W Titanium may mix two types.
- Check your feed: the 800W and 1000W units run on 100–240VAC, but the 1600W Platinum and 1800W-2200W Titanium are high-line only at 200–240VAC.
- Efficiency matters under EU ErP Lot 9: the 1000W Titanium and the 1800W-2200W Titanium are the 96% single-output units.
- Refurbished PSUs are a low-risk buy — sealed, tested modules and a popular way to add redundancy affordably.

DL385 Gen11 Power Supplies FAQ
What power supplies does the HPE ProLiant DL385 Gen11 use?
HPE Flex Slot hot-plug PSUs: 800W Platinum, 1000W Titanium, 1600W Platinum Low Halogen, a 1600W -48VDC unit, and the 1800W-2200W Titanium. The server takes one or two as standard, or four with the Power Distribution Board kit.
Can I mix different power supplies in the DL385 Gen11?
No. Mixing different power supply SKUs is not allowed, so buy the exact part number already installed. The single documented exception is a four-supply configuration that includes the 1800W-2200W Titanium unit.
Does the 1600W power supply work on 110V power?
No. The 1600W Platinum unit supports high line voltage only, 200 to 240VAC, and the 1800W-2200W Titanium has the same requirement. On low-line power use the 800W Platinum or 1000W Titanium, which accept 100 to 240VAC.
Can the DL385 Gen11 take four power supplies?
Yes, with the Power Distribution Board kit. That kit cannot be configured on the 8SFF or 8LFF CTO server, and the 48SFF configuration is documented at its maximum weight with four supplies fitted.
Can I hot-swap a failed DL385 Gen11 power supply?
Yes, provided at least two supplies are installed. Flex Slot modules are tool-less: pull the failed unit and insert an identical replacement without shutting the server down.
Are DL385 Gen11 and DL380 Gen11 power supplies interchangeable?
Both platforms use the HPE Flex Slot family with overlapping wattages, but always match the exact part number listed in your server's QuickSpecs, because the supported lineup differs by platform.
