  • TypeATX
  • Modern Standby support enables extremely fast wake-from-sleep times
  • 80 PLUS Gold certification delivers high efficiency for lower power consumption
  • Zero RPM fan mode stops the fan at low and medium loads for near-silent operation
  • Resonant LLC topology with DC-to-DC conversion provides clean, consistent power and reduces coil whine

KHACHIMO 305W Gold ATX Supply

This 305W ATX power supply carries 80 PLUS Gold certification for high efficiency and lower heat output. It targets office PCs and small-form-factor builds that require Modern Standby compatibility and quiet operation. The unit fits standard ATX bays and replaces several legacy Dell part numbers including 3100, 5100, 5150, 9100 and 960. Builders needing more than 305W or multiple GPU power connectors should look elsewhere.

Modern Standby and Zero RPM Fan

Modern Standby support enables extremely fast wake-from-sleep times and improved low-load efficiency. Zero RPM fan mode stops the cooling fan completely at low and medium loads for near-silent running. Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power and reduces coil whine while allowing deeper sleep states. No modular cables or extra software utilities are mentioned in the data.

Capacity and Headroom

The 305W rating handles typical office workloads, integrated graphics and single low-power add-in cards. Efficiency peaks at 80 PLUS Gold levels, keeping consumption and temperatures down during everyday use. Heavy gaming GPUs, multi-card configurations or sustained loads above 305W exceed this unit’s capacity. The listed part numbers N305P-06, L305P-01, L305P-03, N305P-01, H305P-01 and pc8050 confirm direct replacement scope.

Perguntas sobre este artigo

Will the cooling fan on this 305W unit eventually need replacement after years of continuous use?

The fan spins down completely at low and medium loads thanks to Zero RPM mode, so mechanical wear is far slower than on units that run the fan constantly.

What thermal limit is reached first when this 80 PLUS Gold supply runs at full 305W output for hours?

Gold-rated efficiency keeps waste heat low, so the internal protection thresholds are reached later than on lower-rated designs, letting the supply sustain full load longer.

How much noise and heat does this 305W ATX supply produce when left running all day in a desktop?

At typical desktop loads the fan stays off entirely, delivering near-silent operation and minimal heat thanks to the resonant LLC topology and DC-to-DC conversion.
