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.

Questions about this item

How can I confirm the power supply is operating correctly after installation?

The fan should remain off at low and medium loads thanks to Zero RPM mode, and the system should wake from sleep almost instantly if Modern Standby is enabled in the BIOS.

What cables and accessories are included, and what must I purchase separately?

The package contains the 300 W ATX unit with fixed cables; mounting screws and a power cord are typically included, but any custom sleeved cables or extra PCIe connectors would be separate purchases.

Which of the listed model codes — T40, T3630, T3640 or T3650 — should I choose?

All four codes refer to the same 300 W 80 PLUS Gold platform; pick the code that matches your region or retailer listing, as the internal specifications are identical.
