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

M-CRPS, not Flex Slot. The DL580 Gen12 uses M-CRPS power supply modules — Flex Slot PSUs from other ProLiant models are a physically different form factor and are not listed for this server. All installed supplies must be the identical model.

How many power supplies does the DL580 Gen12 need?

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.

DL580 Gen12 Power Supplies FAQ

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.
