HPE ProLiant DL384 Gen12 Power Supplies
Genuine HPE Flex Slot power supplies for the HPE ProLiant Compute DL384 Gen12, new and refurbished. HPE lists exactly one power supply for this server — the 1800W-2200W Flex Slot Titanium Hot Plug Power Supply Kit — so the decision is not which supply but how many: two, three or four on a single GH200 superchip, and always four on a dual-superchip GH200 NVL2.
DL384 Gen12 Power Supply Specifications
- Power supply: HPE 1800W-2200W Flex Slot Titanium Hot Plug Power Supply Kit, part number P44712-B21, the only power supply listed for this server
- Efficiency: Titanium, up to 96%, single output; HPE names P44712-B21 among the Flex Slot supplies meeting the European Union Lot 9 requirement of 96% for single-output supplies
- Inlet: standard C-14 power inlet connector, one C13 power cord per supply and up to four per server, chosen separately
- Input: rated line voltage of 200 to 240 VAC per power supply
- Bays: up to four power supplies, rear positions 1 to 4, hot plug and tool-less
- Single superchip: two supplies are sufficient, three gives 2+1 redundancy and four gives 2+2 — N+0, N+1 or N+2 in HPE's technical specifications
- Dual superchip NVL2: four supplies are the required configuration, providing 3+1 redundancy (N+1)
- Thermal: 3048 W (10.4k BTU/hr) maximum heat dissipation on a fully populated GH200 NVL2; front-to-back airflow of 52 CFM idle without a DPU, 133 CFM typical with a DPU and 240 CFM at operating maximum
- Total input power: HPE refers sizing to the HPE Power Advisor rather than publishing one figure
Four is not optional on a dual-superchip server. HPE states that a GH200 NVL2 configuration requires four 1800W-2200W Flex Slot Titanium power supplies, which gives 3+1 redundancy, while a single-superchip server runs on two, with a third for 2+1 and a fourth for 2+2. Every bay takes the same part, P44712-B21, so the only decision is how many.
How many power supplies does a DL384 Gen12 need?
| Configuration | Supplies fitted | Redundancy | HPE's wording |
|---|---|---|---|
| Single GH200 | 2 | None (N+0) | Sufficient |
| Single GH200 | 3 | 2+1 (N+1) | Provides 2+1 redundancy |
| Single GH200 | 4 | 2+2 (N+2) | Provides 2+2 redundancy |
| Dual GH200 NVL2 | 4 | 3+1 (N+1) | The required configuration |
The table has one row without a choice in it. A dual-superchip server needs three supplies to carry the load, so its fourth bay buys N+1 and nothing more — there is no 2+2 option on an NVL2, and no configuration in which it runs on fewer than four. A single-superchip server has the flexibility: a lab or development machine can run on two, and each supply added is one more that can fail without a shutdown.
Choosing the Right DL384 Gen12 Power Supply
- Every bay takes the same part. P44712-B21 is the only supply HPE lists, so there is no wattage or efficiency grade to match, only a quantity to reach.
- Do the redundancy math for your superchip count. On a single GH200 the third supply is the first redundant one; on an NVL2 the fourth is, and it is also mandatory.
- Feed it 200 to 240 volts. That is the rated line voltage HPE publishes per power supply, and the tested acoustic configuration ran all four at 2200 W.
- One C13 cord per supply. The kit's inlet is a standard C-14 connector, and HPE lists the country-specific cords as a separate choice.
- Size the room for the heat. A fully populated NVL2 dissipates 3048 W and moves up to 240 CFM front to back at operating maximum.

How many power supplies does a DL384 Gen12 need?
Two are sufficient for a single GH200 superchip, with three giving 2+1 and four giving 2+2 redundancy. A dual-superchip GH200 NVL2 configuration requires four, which provides 3+1 redundancy.
Is the DL384 Gen12 power supply hot-pluggable?
Yes. It is an HPE Flex Slot design with hot-plug, tool-less installation into one of the four rear power supply bays.
What input voltage does the DL384 Gen12 accept?
HPE rates the line voltage at 200 to 240 VAC per power supply, with up to four power supplies per server and one C13 power cord for each.
How efficient is the DL384 Gen12 power supply?
Up to 96%. HPE names P44712-B21 among the single-output Flex Slot supplies that meet the European Union Lot 9 requirement of 96% efficiency for single-output power supplies.
How much heat does a fully loaded DL384 Gen12 produce?
HPE quotes 3048 watts (10.4k BTU/hr) of maximum heat dissipation for a fully populated GH200 NVL2 system, with front-to-back cooling airflow of up to 240 CFM at operating maximum.
Does the power supply kit come with a power cord?
HPE lists the power cords as a separate choice, one per power supply, connecting a C13 plug to the supply's standard C-14 inlet. Match the cord to your country's outlet and the 200 to 240 VAC rating.
