HPE ProLiant DL120 G7 Power Supplies
Genuine HPE power supplies for the HPE ProLiant DL120 G7, new and refurbished. This server ships with one auto-sensing power supply and no redundancy — the part that changes that is the 365W Redundant Power Supply Kit with Backplane, and because the kit brings the backplane with it, redundancy here is a chassis change rather than simply adding a second unit.
DL120 G7 Power Supply Specifications
- As shipped: one auto-sensing, power-factor-corrected, CE Mark compliant supply — not redundant, and there is no second supply bay until the redundant kit's backplane is fitted
- Redundancy option: the HPE 365W Redundant Power Supply Kit with Backplane, which supplies the backplane as well as the unit
- Redundant kit input: 100 to 240 VAC at a nominal 50/60Hz frequency range
- Redundant kit output: 320W maximum rated output at 100 and 120 VAC, rising to 360W from 200 VAC upward
- Redundant kit efficiency: 77.4% at 100 VAC at maximum rated output, rising to 81.0% at 240 VAC, at a 0.99 power factor
- Baseline to size against: HPE's 400W supply figures for this chassis are 400W rated steady-state power and 430W maximum peak, on a 90–132 VAC or 180–264 VAC line at 47 to 63Hz
- Cooling: four dual-rotor fans ship standard and are not hot-plug; HPE notes system performance may be reduced with a fan fault or above 30°C
Redundancy on this server costs capacity, and costs more of it on a low-line feed. The 365W Redundant Power Supply Kit is rated 320W at 100 and 120 VAC against 360W at 200 VAC and above — both under the 400W steady-state rating HPE publishes for the supply the server ships with. Check the real draw before trading one for the other.
What does the redundant kit change?
| Supply as shipped | 365W Redundant Power Supply Kit | |
|---|---|---|
| Redundancy | None | Yes — the kit includes the backplane |
| Rated output | 400W steady state, 430W peak | 320W at 100 and 120 VAC; 360W at 200 VAC and above |
| Input range | 90–132 VAC and 180–264 VAC | 100 to 240 VAC |
| Maximum BTU rating | 1943 BTU/hr | 1334 to 1462 BTU/hr by input voltage |
Redundancy costs headroom on this platform, and costs more of it on a low-line feed: the same kit is rated 320W at 100 and 120 VAC against 360W from 200 VAC upward, and both sit under the 400W steady-state rating HPE publishes for the shipped supply. On a machine carrying four drives, a Smart Array card and a network adapter, that gap is worth checking against the real draw.
Choosing the Right DL120 G7 Power Supply
- Redundancy is a kit, not a spare supply. HPE's redundant option ships a backplane with the unit, because a standard DL120 G7 has nowhere to put a second supply without it.
- Feed it high line if the rack allows. The efficiency follows the output: 77.4% at 100 VAC at maximum rated output against 81.0% at 240 VAC, from the same kit.
- Size the configuration before you trade 400W for 365W. The supply the server ships with is rated 400W steady state and 430W peak, so the redundant kit is a step down in capacity as well as a step up in resilience.
- The fans are not part of this purchase. Four dual-rotor fans ship standard and are not hot-plug, so a fan fault on this server is a shut-down-and-open job rather than a hot swap.

DL120 G7 Power Supplies FAQ
Is the DL120 G7 power supply redundant?
Not as shipped. The server ships with a single auto-sensing power-factor-corrected supply. Redundancy comes from the 365W Redundant Power Supply Kit with Backplane, which supplies the backplane as well as the unit.
What wattage is the DL120 G7 power supply?
HPE publishes 400W rated steady-state power and 430W maximum peak for the supply the server ships with. The redundant kit is rated 320W at 100 and 120 VAC and 360W at 200 VAC and above.
Why is the redundant kit rated lower than the standard supply?
It is a different supply. HPE rates the 365W redundant kit at 320W on a low-line feed and 360W on a high-line one, where the shipped supply is rated 400W steady state, so redundancy trades a little capacity for a second unit.
What input voltage does a DL120 G7 accept?
The redundant kit takes 100 to 240 VAC at a nominal 50/60Hz. HPE's figures for the 400W supply are a 90 to 132 VAC or 180 to 264 VAC line at 47 to 63Hz.
Are the fans in a DL120 G7 hot-plug?
No. Four dual-rotor fans ship standard and are not hot-plug. HPE notes that system performance may be reduced when the server runs with a fan fault or above 30 degrees Celsius.
How much heat does a DL120 G7 give off?
HPE publishes a maximum of 1943 BTU/hr against the 400W supply figures. The 365W redundant kit is rated between 1334 and 1462 BTU/hr depending on the input voltage.
