240W ATX power supply for compact PCs

The KHACHIMO 240W ATX unit delivers 240 watts of continuous power in a standard ATX form factor. It suits small-form-factor desktops and office workstations that require reliable, efficient energy delivery. The 80 PLUS Gold certification ensures high efficiency across typical loads. This PSU is not for builds needing more than 240W or multiple high-power graphics connectors.

Sustained load behaviour with Gold efficiency

Under continuous load the resonant LLC topology with DC-to-DC conversion maintains clean, consistent voltage regulation. The 80 PLUS Gold rating keeps waste heat and fan noise low during extended sessions. Zero RPM fan mode stays active at low and medium loads, switching the fan off entirely for near-silent operation. Coil whine is reduced by the same topology.

Modern Standby compatibility for instant wake

The single specification that decides fit is Modern Standby compatibility, enabling extremely fast wake-from-sleep times and better low-load efficiency. This feature is required for systems that use modern sleep states. If the target platform does not support Modern Standby, this advantage cannot be used. The unit provides a 6Pin+4Pin connector set for the motherboard.

Questions about this item

How quiet is the 240W unit with its Zero RPM fan mode during all-day use?

At low and medium loads the fan stops completely, giving near-silent operation, while 80 PLUS Gold efficiency keeps heat and noise low even under sustained load.

Which cables must my build already provide for this ATX supply to work?

The unit includes a 6-pin and a 4-pin connector, so your motherboard and graphics card need matching headers for power delivery.

Will the resonant LLC topology with DC-to-DC conversion work reliably with older components I keep?

Yes, the topology delivers clean, consistent power and supports modern sleep states, making it compatible with legacy hardware that uses standard ATX rails.
