Need the black micro-ATX 24-pin connector version?

This listing is for the standard-size white 24-pin ATX connector. If your original power supply has the smaller black micro-ATX 24-pin connector, see the 437798-001 240W Power Supply with Black Micro-ATX Connector.

The white standard-size connector and black micro-ATX connector are physically different. Compare the original connector carefully before ordering.

Need a C13 AC power cord?

This power supply has a standard IEC C14 inlet and requires a grounded NEMA 5-15P to IEC C13 AC power cord for North American outlets. The AC power cord is sold separately.

See the 121565-004 / 121565-001 6 FT NEMA 5-15P to IEC C13 AC Power Cord.

✅ Confirmed Compatibility

Compatibility depends on the desktop form factor, original power-supply part number, connector size and color, mounting points, rear AC inlet position, and internal cable configuration. Verify the original PSU before ordering.

⚙️ Fit Notes

• This listing is specifically for the standard-size white 24-pin ATX connector version.
• Do not confuse this PSU with part number 437798-001, which uses the smaller black micro-ATX 24-pin connector.
• Although both connector styles have 24 pins, their physical size and pin spacing are different. Do not force either connector into the motherboard socket.
• Confirm that the original power supply is labeled with one of the interchangeable part numbers listed above.
• Compare the mounting tabs, screw locations, rear AC inlet position, connector layout, and cable routing before installation.
• This is a proprietary Small Form Factor power supply chassis. It is not a standard retail ATX power supply.
• Compatibility is for the SFF versions of the listed desktops. Convertible Minitower and Ultra-Slim Desktop versions use different power supplies.
• Disconnect the computer from AC power before removing or installing the power supply.
