Built for LEO AT systems

The KHACHIMO LEO AT 300W Power Supply LPS-300W is a 300 watt ATX unit designed specifically for compatible LEO AT builds. It targets system integrators and owners of those platforms who need a direct replacement or original equipment power source. It is not for builders using standard ATX cases or motherboards that require higher wattage or different connector layouts.

Sustained-load behaviour

The 80 PLUS Gold certification confirms high efficiency across typical operating ranges, meaning less energy is wasted as heat during continuous use. Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power output and supports modern, energy-efficient sleep states. This architecture helps maintain stable voltage regulation when the system runs for extended periods.

Thermals, noise and power draw

Zero RPM fan mode stops the cooling fan entirely at low and medium loads, providing near-silent operation during everyday tasks. The high-efficiency design reduces overall power consumption and keeps internal temperatures lower than less efficient units. Modern Standby compatibility enables extremely fast wake-from-sleep times while maintaining low-load efficiency.

Preguntas sobre este artículo

How quiet is the 300W unit during all-day use?

The Zero RPM fan mode stops the fan at low and medium loads, while the resonant LLC topology with DC-to-DC conversion reduces coil whine for near-silent operation.

What must my case and motherboard already provide for this PSU to work?

An ATX-form-factor case bay and a motherboard with standard ATX 24-pin and CPU power connectors are required for installation.

Will the 80 PLUS Gold efficiency help when paired with older components that draw less power?

Yes, the Gold certification and Modern Standby support deliver high efficiency and fast wake times even at the low loads typical of older hardware.
