HPE ProLiant ML310e Gen8 v2 Power Supplies
Genuine HPE power supplies for the HPE ProLiant ML310e Gen8 v2, new and refurbished. This tower left the factory two ways, with a 350W multi-output supply that is not redundant or with hot-plug Common Slot units — and because HPE does not support mixing supplies, moving between the two is a swap, never an addition.
ML310e Gen8 v2 Power Supply Specifications
- Supply listed here: the HPE 460W Common Slot Gold hot-plug kit, rated up to 92% efficiency, supplied with one PDU IEC cable
- Factory alternative: a 350W multi-output supply with an 85% efficiency rating, documented for this server as a non-redundant unit
- Redundancy: optional 1+1, built from matching Common Slot supplies rather than from the 350W unit
- Enablement: HPE documents a 4U Redundant Power Supply Enablement Kit as a required install when Common Slot supplies are used — a platform requirement, not part of this listing
- Mixing: not supported — every supply in one server must be exactly the same model, and Gold, Platinum and Platinum Plus cannot be combined
- Input: 100 to 240 VAC at 47 to 63 Hz, 6 amps rated input current, 440W rated input power at both 100V and 200V AC
- Cooling: one system fan and one PCIe fan ship as standard, neither of them redundant
Mixing power supplies is not supported, and a 460W unit is not a partner for a 350W one. Every supply in the server must be exactly the same model, so redundancy on a 350W machine means a matched pair of Common Slot units, not a second supply added beside the first. Read the label before ordering.
Is a second supply worth what it costs you?
| 350W multi-output | 460W Common Slot Gold | |
|---|---|---|
| Efficiency rating | 85% | Up to 92% |
| Hot-plug | No | Yes |
| Redundant pair | Not supported | 1+1 with a matching unit |
| Media bays left | Two | One, once the redundant supply is in |
That last row is the detail people miss: HPE documents that once a redundant supply is installed, bay A becomes the only media bay available, so the second optical bay is part of the price of redundancy. Read the label on the supply already fitted before ordering, because a 460W Common Slot unit is not a partner for a 350W one — it is a replacement for it.
Choosing the Right ML310e Gen8 v2 Power Supply
- The installed supply is the specification. Matching model and efficiency rating is a requirement rather than a preference, so read the label before you order anything.
- One Common Slot supply is not redundancy. A 1+1 configuration is two identical units, and HPE also calls for the 4U redundant power supply enablement kit underneath them.
- Size it to the machine. A single-socket tower with four drives sits well under 460W; the documented maximum for this server is 1773 BTU per hour at 120 VAC.
- Fans are not part of the redundancy story. Both fans ship non-redundant, so a second supply protects against a supply failure only.
- Refurbished suits this part well. A Common Slot supply is a sealed unit shared across many ProLiant generations, which makes a tested used one a sound way to build a matched pair.

ML310e Gen8 v2 Power Supplies FAQ
Which power supply does the ML310e Gen8 v2 use?
HPE documents two: a 350W multi-output supply rated at 85% efficiency, which is not redundant, and the 460W Common Slot Gold hot-plug supply rated up to 92%. The Common Slot unit is the one listed here.
Can I add a 460W supply alongside the 350W one already fitted?
No. Mixing power supplies in one server is not supported - every supply must be exactly the same model. Moving a 350W machine to redundancy means a matched pair of Common Slot units instead.
Is the ML310e Gen8 v2 redundant on power as standard?
No. Redundancy is optional and built from matching Common Slot supplies in a 1+1 arrangement. HPE also documents a 4U redundant power supply enablement kit as a required install when Common Slot supplies are used.
Does adding a second power supply cost me anything?
One media bay. HPE documents that once the redundant power supply is installed, bay A becomes the only media bay available for use.
Are the fans redundant on this server?
No. One system fan and one PCIe fan ship as standard and HPE documents both as non-redundant, so a second power supply covers supply failure only.
What input does the power supply need?
100 to 240 VAC at 47 to 63 Hz, drawing a rated 6 amps, with a rated input power of 440W at both 100V and 200V AC. The tower ships with a standard country-specific wall power cord.
