KHACHIMO H9-1400 750W ATX power supply

This KHACHIMO unit delivers 750 W of continuous power in a standard ATX form factor. It is built for desktop builders who need reliable, efficient energy delivery for modern components. The 80 PLUS Gold certification confirms high efficiency across typical loads. Modern Standby compatibility ensures extremely fast wake-from-sleep times and better low-load efficiency.

750 W capacity with Gold efficiency headroom

The 750 W rating comfortably handles mid-range to high-end graphics cards and multi-core processors under full load. Efficiency remains high at 80 PLUS Gold levels, reducing waste heat and lowering electricity draw during extended sessions. At low and medium loads the Zero RPM fan mode stops the fan entirely for near-silent operation. Heavy sustained loads will eventually spin the fan up to maintain safe temperatures.

Resonant LLC topology with DC-to-DC conversion

This topology provides clean, consistent power and reduces coil whine for quieter operation. It also enables use of more energy efficient sleep states supported by modern platforms. The design targets builders who prioritise low noise and stable voltage regulation. Systems requiring specialised server-grade redundancy or extreme overclocking headroom should evaluate alternative units.

Questions about this item

Will the 80 PLUS Gold 750W unit power my older ATX motherboard and graphics card without adapters?

The PSU follows the standard ATX form factor and provides the usual 24-pin, CPU and PCIe connectors, so it fits legacy builds directly.

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

Under light loads the fan stays completely still; you will hear no spinning noise until the system draws more power.

Which cables come attached to the DPS-750AB-40B and what must I source separately?

Fixed ATX 24-pin, EPS and PCIe leads are built in; only specialised adapters for legacy drives or extra GPU power would need separate purchase.
