ATX 255W Gold PSU

The KHACHIMO 255W ATX power supply delivers 80 PLUS Gold certified efficiency for desktop systems requiring reliable power conversion. Modern Standby compatibility ensures extremely fast wake-from-sleep times and improved low-load efficiency. Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation. Resonant LLC topology with DC-to-DC conversion provides clean, consistent power while reducing coil whine.

Replaces older ATX units lacking Gold efficiency

Upgrading from a non-certified or lower-rated power supply reduces power consumption, noise output, and operating temperatures. The jump is worthwhile when building or refreshing a system that spends long periods at idle or in sleep states where Modern Standby and zero-fan operation deliver measurable benefits. Systems requiring higher wattage than 255W cannot use this unit.

Fits standard ATX builds

The ATX form factor allows installation in compatible chassis designed for this layout. DC-to-DC conversion supports energy-efficient sleep states on supported platforms. Builders needing more than 255W of continuous power, additional PCIe connectors not listed, or a different form factor such as SFX must select an alternative unit.

Questions sur cet article

What ATX case dimensions does the 255W KHACHIMO unit require?

It follows the standard ATX form factor, so any chassis with an ATX power-supply bay and rear cut-out will accept it.

Which cables must be connected first to enable Modern Standby on the 255W supply?

Plug the 24-pin ATX and 4+4-pin CPU connectors into the motherboard before switching on the mains; the unit then negotiates low-power states automatically.

How do I clean the fan on this 255W Gold unit without voiding the new condition?

Power off, unplug, and use short bursts of compressed air through the intake grille; the Zero RPM mode keeps the fan stationary at low load, reducing dust build-up.
