KHACHIMO R4900 G3 850W ATX Power Supply

The KHACHIMO R4900 G3 is an 850W ATX power supply built for modern desktop PCs. It carries 80 PLUS Gold certification for high efficiency, lowering power draw and heat output. A Zero RPM fan mode stops the fan completely at low and medium loads for silent running. Resonant LLC topology with DC-to-DC conversion delivers clean, stable power and reduces coil whine.

Ideal for efficient, quiet desktop builds

This unit suits builders who want Gold-rated efficiency and near-silent operation at typical workloads. Modern Standby compatibility provides extremely fast wake-from-sleep times and better low-load efficiency. It is not for systems that require a different form factor or wattage rating. Buyers needing fully modular cabling or a specific connector count not listed here should verify compatibility separately.

850W Gold ATX with Zero RPM and Modern Standby

The 850W rating defines the maximum continuous power available to components. Gold certification confirms high efficiency across the load range. Zero RPM mode enables fanless operation at low and medium loads. Modern Standby support allows faster sleep wake and deeper sleep states. Resonant LLC with DC-to-DC conversion ensures tight voltage regulation and low noise.

Perguntas sobre este artigo

Which KHACHIMO R4900 G3 850W version should I pick?

The DPS-850AB-4J is the single 850W ATX unit offered; choose it when your build needs 850 watts from a Gold-rated supply with Modern Standby support.

What does the 850W rating mean once the PSU is installed?

It can deliver up to 850 watts continuously to your components while maintaining 80 PLUS Gold efficiency, so the system draws less power from the wall and runs cooler.

What interface does the DPS-850AB-4J use and what does it limit?

It uses the standard ATX interface, which limits the unit to ATX-compatible cases and motherboards with 24-pin and EPS connectors.
