440 W ATX Gold Power Supply

This KHACHIMO unit delivers 440 W of continuous DC power through an ATX form factor. It carries 80 PLUS Gold certification for high efficiency at typical loads. Modern Standby compatibility enables extremely fast wake-from-sleep times. Resonant LLC topology with DC-to-DC conversion provides clean power and reduces coil whine.

Ideal for efficient mainstream builds

The supply suits builders who want Gold-rated efficiency, silent low-load operation via Zero RPM fan mode, and Modern Standby support in a standard ATX chassis. It is not for systems that require higher wattage headroom, redundant power modules, or server-grade form factors such as EPS or TFX.

440 W rated output decides fit

The single 440 W rating determines whether this unit can power your chosen components. Verify total system draw against this figure before purchase. If your build demands more power, you must select a higher-wattage model.

Questions sur cet article

What physical space does this ATX power supply require inside a case?

It uses the standard ATX form factor, so it fits any chassis with an ATX power-supply bay and clears the 440 W rating label on the rear.

What is the key step to enable Modern Standby when installing this unit?

Connect the 24-pin ATX and 8-pin CPU cables, then enable Modern Standby in the motherboard firmware; the most common mistake is leaving the feature disabled in BIOS.

How does the Zero RPM Fan Mode affect long-term dust buildup?

Because the fan stops at low and medium loads, less air moves through the unit, so schedule a yearly clean with compressed air to prevent dust accumulation.
