240W ATX Power Supply

This 240W ATX unit delivers efficient power for compact desktops and small-form-factor office machines. It suits builders who need a reliable supply for low-draw CPUs and integrated graphics. It is not for gaming rigs that require discrete graphics cards or higher continuous wattage.

Standard ATX Installation

The supply follows the ATX form factor, so it fits standard chassis mounting points and uses common motherboard connectors. Cable routing is straightforward in tight cases because the unit is non-modular. Ensure the case has enough depth for the fixed cable bundle before ordering.

240W Gold Efficiency Headroom

80 PLUS Gold certification means high efficiency across typical loads, reducing heat and fan noise. Zero RPM mode keeps the fan off at low and medium demand for silent operation. The 240W limit caps headroom for power-hungry components; sustained heavy loads will run out of capacity quickly.

  • 80 PLUS Gold efficiency cuts power draw and heat

Questions about this item

How can I confirm the 240W unit is running correctly after installation?

The fan should stay off under light loads because of the Zero RPM mode, and the system should wake from sleep almost instantly thanks to Modern Standby support.

What comes with the 240W power supply and what must I purchase separately?

The box contains the ATX power supply unit and its fixed cables; mounting screws and a mains power cord are not included and must be sourced separately.

Which of the listed part numbers such as 3WN11, L240AS-00 or H240ES-00 should I select for my build?

All listed codes refer to the same 240W ATX model with 80 PLUS Gold certification, so choose the exact part number that matches your chassis or motherboard documentation.
