KHACHIMO T40 300W 80 PLUS Gold ATX power supply

300W Gold ATX PSU for Modern Standby

The KHACHIMO T40 is a 300W ATX power supply certified 80 PLUS Gold for high efficiency and lower running costs. It targets builders of compact or office systems that require Modern Standby support for fast wake-from-sleep behaviour. The unit uses a resonant LLC topology with DC-to-DC conversion to deliver clean power and enable deeper sleep states.

Standard ATX fit with semi-passive cooling

Installation follows the standard ATX form factor and mounting pattern used by most chassis. The Zero RPM fan mode stops the fan completely at low and medium loads, reducing noise without extra configuration. Ensure the case provides adequate airflow around the unit, as restricted ventilation can prevent the fan from spinning down or cause thermal throttling under sustained load.

300W continuous output limits high-end builds

The single deciding specification is the 300W rated capacity, which suits entry-level CPUs and integrated graphics or low-power discrete cards. Systems with mid-range or high-end graphics cards, multiple drives, or heavy overclocking will exceed this limit and require a higher-wattage unit. Buyers planning such configurations should select a supply with greater continuous power.
