HPE ProLiant DL580 Gen12 Power Supplies
Genuine HPE power supplies for the HPE ProLiant DL580 Gen12, new and refurbished. This platform uses the M-CRPS (Modular Common Redundant Power Supply) family — not the Flex Slot units found in most 1U/2U ProLiants — in Titanium-efficiency hot-plug modules sized for two- and four-processor configurations.
DL580 Gen12 power supply specifications
- Family: M-CRPS hot-plug, tool-less modules; 80 PLUS Titanium efficiency
- AC options: 1500W, 2400W, and 3200W
- DC option: 2200W –48VDC (with a separate power lug kit for hard-wired installations)
- Rules: all installed PSUs must be the same model; 2-processor systems run 1–2 PSUs, 4-processor systems require 2 or 4
How many power supplies does the DL580 Gen12 need?
| Configuration | Minimum PSUs | For redundancy |
|---|---|---|
| 2 processors | 1 | 2 |
| 4 processors | 2 | 4 |
Production systems should always run the redundant count — hot-plug modules then let you replace a failed supply without downtime.
Choosing the right DL580 Gen12 power supply
- Never mix wattages or models — HPE requires all PSUs in the chassis to be identical.
- Size for the loaded configuration: four 350W processors, 64 DIMMs, and 32 NVMe drives demand far more headroom than a 2P starter build — HPE's Power Advisor sizes it precisely, or send us your config and we'll check it.
- Match your feed: high-line AC for standard datacenter power; the –48VDC unit (plus lug kit) for telecom and DC-plant environments.
- Buying refurbished PSUs is low-risk: they're sealed, tested modules — a popular way to add redundancy affordably.

Frequently asked questions
What power supplies does the HPE ProLiant DL580 Gen12 use?
M-CRPS (Modular Common Redundant Power Supply) hot-plug modules: 1500W, 2400W, and 3200W AC units at 80 PLUS Titanium efficiency, plus a 2200W -48VDC option for DC power plants.
Are Flex Slot power supplies compatible with the DL580 Gen12?
No. The DL580 Gen12 uses the M-CRPS form factor; Flex Slot PSUs from other ProLiant models are a physically different module and are not listed for this server.
How many power supplies does a 4-processor DL580 Gen12 require?
Either two or four - and four for redundancy. Two-processor configurations run on one PSU with a second for redundancy. All installed supplies must be the same model and wattage.
When do I need the 3200W power supply?
For heavily loaded 4-processor systems - high-TDP Xeon 6 CPUs, fully populated memory, and dozens of NVMe drives. Lighter 2P configurations are typically fine on 1500W units; size the exact build with HPE Power Advisor or ask us to check your configuration.
Can I hot-swap a failed DL580 Gen12 power supply?
Yes, provided the system is running with redundancy: with 2 (or 4) matching PSUs installed, a failed module can be pulled and replaced without shutting the server down.
