HPE ProLiant DL380 Gen9 Power Supplies
Genuine HPE Flex Slot power supplies for the HPE ProLiant DL380 Gen9, new and refurbished. The platform takes a maximum of two hot-plug Flex Slot supplies, and the rule attached is absolute: all supplies in one server must share input voltage, output and efficiency rating.
DL380 Gen9 Power Supply Specifications
- Wattages: 500W and 800W Flex Slot Platinum, 800W Flex Slot Titanium and 1400W Flex Slot Platinum Plus hot-plug kits
- Efficiency: Platinum and Platinum Plus supplies support up to 94%; the 800W Titanium supports up to 96%
- Input: rated line voltage 100 to 120 VAC and 200 to 240 VAC, but the 1400W supply is documented at 200 to 240 VAC only
- DC variants: an 800W Flex Slot -48VDC kit, with 277VAC and 380VDC inputs also listed
- Heat output: a maximum of 3207 and 3071 BTU/hr at 100 and 200 VAC for the 800W supply, 1979 and 1911 BTU/hr for the 500W
- Cords and features: each standard AC kit includes a 6-foot IEC C-13/C-14 jumper cord, and Power Discovery Services comes with the 1400W
Check your feed before you size the supply. HPE documents the 1400W Flex Slot Platinum Plus rated steady-state output at 240 VAC and its maximum peak power at 200 to 240 VAC, with no 100 VAC figure printed; the 500W and 800W are rated at both. The platform takes two supplies at most, and both must match on input voltage, output and efficiency.
What does each DL380 Gen9 power supply actually deliver?
| Supply | Efficiency | Rated steady-state output | Documented input |
|---|---|---|---|
| 500W Flex Slot Platinum | Up to 94% | 500W at 100 VAC and at 240 VAC | 100–120 or 200–240 VAC |
| 800W Flex Slot Platinum | Up to 94% | 800W at 100 VAC and at 240 VAC | 100–120 or 200–240 VAC |
| 800W Flex Slot Titanium | Up to 96% | 800W at 100 VAC and at 240 VAC | 100–120 or 200–240 VAC |
| 1400W Flex Slot Platinum Plus | Up to 94% | 1400W at 240 VAC | 200–240 VAC |
| 800W Flex Slot -48VDC | Up to 94% | 800W | -48VDC |
The 1400W is the one to read carefully. HPE documents its rated steady-state output and maximum peak power at 200 to 240 VAC, while the 500W and 800W are printed at both 100 VAC and 240 VAC. It is also what HPE names for double-wide graphics cards above 150W, one per card.
Choosing the Right DL380 Gen9 Power Supply
- Never mix supplies. HPE states all must share input voltage, output rating and efficiency rating, and that non-matching supplies may produce an error or operational issues.
- Two bays, and that is the ceiling. HPE states a maximum of two Flex Slot supplies, so redundancy means a matching second unit.
- Right-size before you buy. HPE recommends the Power Advisor first; a 1P 8SFF base server ships with one 500W supply, a 2P performance build with two 800W.
- Titanium buys efficiency, not watts. The 800W Titanium delivers the same 800W at up to 96% rather than 94%.
- Refurbished supplies are a low-risk buy — sealed, tested hot-plug modules, and the usual way to fill the second bay.

DL380 Gen9 Power Supplies FAQ
What power supplies does the HPE ProLiant DL380 Gen9 use?
HPE Flex Slot hot-plug supplies. The QuickSpecs list a 500W Platinum, an 800W Platinum, an 800W Titanium at up to 96% efficiency, a 1400W Platinum Plus, and an 800W -48VDC variant. Flex Slot supplies install tool-lessly and are shared across ProLiant Gen9 performance servers.
How many power supplies does a DL380 Gen9 hold?
Two. HPE states a maximum of two Flex Slot power supplies per platform, in hot-plug bays at the rear. A one-processor base configuration ships with a single supply, and a second matching unit provides redundancy.
Does the 1400W supply work on a 120V circuit?
Treat it as a high-line supply. HPE documents the 1400W Flex Slot Platinum Plus rated steady-state output at 240 VAC and its maximum peak power at 200 to 240 VAC, with no 100 VAC figure printed. The 500W and 800W supplies are rated at both 100 VAC and 240 VAC.
Can I mix power supplies in a DL380 Gen9?
No. HPE states that all power supplies must be of the same input voltage, output rating and efficiency rating, and that non-matching supplies may produce an error message or operational issues. Mixing can also limit or disable power redundancy.
Which power supply do I need for a GPU in a DL380 Gen9?
For double-wide graphics cards drawing more than 150W, HPE requires at least one 1400W Flex Slot supply per card. Cards rated 150W or under can run on 800W supplies, and HPE recommends checking the actual draw in the Power Advisor.
Do DL380 Gen9 power supply kits include a power cord?
The standard AC option kits include a 6-foot IEC C-13/C-14 jumper cord, the same cord shipped with pre-configured servers. If your rack needs a different cord, such as a wall-outlet cord rather than a PDU jumper, order it separately.
