KHACHIMO V440 680W ATX PSU

The KHACHIMO V440 is a 680 watt ATX power supply built for modern desktop systems. It carries 80 PLUS Gold certification for high efficiency and lower running temperatures. Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power and reduces coil whine. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency.

Ideal for quiet, efficient builds.

This unit suits builders who value near-silent operation and low power draw at idle. The Zero RPM fan mode stops the cooling fan entirely at low and medium loads for silent running. It is not suited for configurations that demand substantially more than 680 watts of continuous power. Buyers needing higher wattage for multiple high-end graphics cards should look at larger capacity units.

Fits standard ATX cases; frees acoustic headroom

The ATX form factor fits standard chassis designs without special mounting requirements. High efficiency and the Zero RPM mode reduce case temperatures and system noise, freeing acoustic headroom for other components. Modern Standby support allows the platform to enter deeper sleep states while maintaining quick resume. Ensure your motherboard and case provide standard ATX power connections for full compatibility.

Questions about this item

What motherboard power connector does the V440 680W unit require to deliver power to the system?

It uses a standard ATX connector so any motherboard with a matching 24-pin socket will receive power from the supply.

How does the V440 680W supply behave when paired with older components that draw less power at idle?

Zero RPM Fan Mode stops the fan completely at low and medium loads, so legacy parts that run cooler keep the system near-silent.

How can I confirm the V440 680W is operating efficiently after installation?

The 80 PLUS Gold rating means it maintains high efficiency across typical loads, and Modern Standby compatibility shows the system wakes quickly from sleep.
