  • ATX form factor fits standard desktop builds

Modern Standby Power Supply

The KHACHIMO BD-309 is an ATX power supply designed for desktop PCs that use Modern Standby sleep states. Its 80 PLUS Gold certification delivers high efficiency, reducing power draw and heat output. The resonant LLC topology with DC-to-DC conversion provides clean, consistent voltage regulation. This unit suits builders who want fast wake times and quieter operation.

Dual 360 W Output Headroom

Two independent 24 V rails each supply up to 360 W, giving a combined capacity for demanding components. The design handles high-load scenarios while maintaining stable voltage across both rails. At low and medium loads the Zero RPM fan mode stops the fan completely for silent running. Systems requiring more than 360 W per rail will exceed the unit's rated output.

80 PLUS Gold Efficiency Rating

This certification confirms the supply meets strict efficiency targets at typical loads, lowering electricity costs and thermal load. The resonant LLC topology further reduces coil whine and supports deeper sleep states. Buyers who need a lower efficiency tier or a different form factor should consider other options.

商品問答

Will the KHACHIMO BD-309 fit an older ATX case and power a legacy motherboard?

Yes, it uses the standard ATX form factor and provides 24 V output with 360 W per rail, matching traditional ATX pinouts for direct compatibility with older motherboards and cases.

How can I confirm the Zero RPM fan mode is active after installation?

Under light or medium loads the cooling fan stops completely; you can verify silent operation by listening for no fan noise while the system idles or runs low-demand tasks.

Which cables come with the BD-309 and what must I source separately?

The unit ships with fixed ATX power cables including the 24-pin motherboard connector and PCIe leads; any specialised adapters or extra-long cables for non-standard chassis are not included.
