This 400W internal power supply is designed for compatible Z240 Tower Workstation configurations. It features a proprietary 6-pin motherboard power connector, 4-pin processor power connector, and 6-pin PCIe auxiliary power connector. Its standard-size metal enclosure does not indicate universal ATX electrical compatibility; the connector layout and original part number must match before installation.

Compatibility is limited to Z240 Tower configurations originally equipped with the matching 400W power supply and proprietary connector layout. The physically different Z240 Small Form Factor power supply is not compatible.
✔️ Z240 Tower Workstation: Compatible configurations originally equipped with a 400W 80 Plus Platinum power supply
✔️ Z240 Convertible Minitower Workstation: Compatible tower configurations using part number 796346-001, 796416-001, L03088-001, PCE009, or PS-5401-1HA
✔️ Z240 Tower Skylake Configurations: Compatible tower systems using select Intel Xeon E3-1200 v5, 6th-generation Core, Pentium, or Celeron processors when the original power-supply connector layout matches
✔️ Z240 Tower Kaby Lake Configurations: Compatible tower systems using select Intel Xeon E3-1200 v6 or 7th-generation Core processors when the original power-supply connector layout matches
✔️ Graphics-Equipped Z240 Tower Configurations: Supports compatible graphics configurations requiring one 6-pin PCIe auxiliary power connection and operating within the system’s available power limits
☑️ 400W maximum output power
☑️ 80 Plus Platinum efficiency rating
☑️ Up to 92% power efficiency
☑️ Proprietary 6-pin motherboard power connection
☑️ Dedicated 4-pin +12V processor power connection
☑️ 6-pin PCIe auxiliary power connector for compatible graphics cards
☑️ Integrated cooling fan
☑️ Direct replacement for all listed interchangeable part numbers
• This power supply is intended for the Z240 Tower / Convertible Minitower chassis.
• It is not compatible with the Z240 Small Form Factor chassis, which uses a physically different power supply.
• Although the enclosure measures 150mm × 86mm × 140mm, the proprietary 6-pin motherboard connector prevents it from functioning as a universal standard ATX replacement.
• Do not connect the proprietary 6-pin motherboard cable to a PCIe graphics-power socket. These connectors may appear similar but have different wiring and functions.
• Confirm the original power supply’s part number, wattage, dimensions, mounting points, cable lengths, and complete connector layout before ordering.
• Verify that any installed graphics card requires no more than one 6-pin PCIe auxiliary power connector and remains within the workstation’s supported power limits.
• Internal SATA drive power may be distributed through separate system-specific cables or motherboard connections. Do not assume that additional drive-power cables or adapters are included.
• This listing includes the power supply only. The required HP 121565-001 C13 AC power cable, internal drive cables, adapters, and all other accessories are sold separately.
