280 W 14-Pin ATX Power Supply

This 280 W desktop power supply uses a 14-pin ATX connector layout. It is intended for proprietary small-form-factor systems that require this specific pinout. Standard ATX motherboards with 20-pin or 24-pin connectors are not compatible.

Single fixed-cable design

The unit is non-modular, so all cables are permanently attached. Installation is straightforward in the correct chassis, but cable routing space is limited. The 14-pin main connector is the most common fitment issue; verify the motherboard header before ordering.

Check motherboard power header

Confirm that your motherboard uses a 14-pin ATX power input and that the physical keying matches. Ensure the case can accommodate a standard PSU mounting pattern and that the fixed cable lengths reach all required components.

Questions about this item

How can I verify the 280 W Lite-On PS-4281-02 is working correctly after installation?

The system should power on and remain stable under load; the single fan should spin and the unit must deliver its rated 280 W without unexpected shutdowns.

What cables are included with the PS-4281-02 and what must I source separately?

Only the cables shown in the product photos are supplied; any additional ATX, CPU or peripheral connectors not pictured will need to be obtained separately.

Which connector version should I choose for a motherboard that requires a 14-pin ATX power header?

The PS-4281-02 is built with a fixed 14-pin ATX connector, so it matches motherboards designed for that specific pin layout.
