KHACHIMO

KHACHIMO 300W Power Supply FSP300-10TAA

SKU CH-D1M9-PQ3V8

A 300 W ATX unit with 80 PLUS Gold efficiency, Zero RPM fan mode and Modern Standby support for silent, low-power sleep states

  • TypeATX
  • Fast wake from sleep with Modern Standby support
  • 80 PLUS Gold efficiency cuts power use and heat
  • Fan stays off at low loads for silent running
  • LLC resonant topology with DC-to-DC delivers clean power
  • ATX form factor fits standard desktop cases

300W ATX Power Supply for Modern Standby Systems

This 300 watt ATX unit is built for desktops that rely on Modern Standby sleep states. The DC-to-DC topology and Gold-rated efficiency suit compact or office builds where low idle power and fast wake times matter more than high peak output. It is not suited for systems with discrete graphics cards or multi-drive arrays that demand sustained power above the rated limit.

80 PLUS Gold Efficiency at 300W

The single specification that decides fit is the 300 watt continuous rating backed by 80 PLUS Gold certification. This guarantees high efficiency across typical loads, reducing heat and electricity cost. If your configuration draws more than 300 watts under full load, this unit cannot deliver the required power and a higher-capacity supply must be chosen.

Zero RPM Fan and LLC Resonant Topology Under Load

At low and medium loads the fan stops completely, eliminating noise during everyday tasks. The resonant LLC topology with DC-to-DC conversion maintains tight voltage regulation and suppresses coil whine when the system ramps up, so sustained workloads run cooler and quieter without fan-speed spikes.

Perguntas sobre este artigo

How does the 300 W rating translate in a built system?

It delivers up to 300 W of continuous power to the motherboard, CPU, drives and graphics card combined, so the total component draw should stay below that figure.

What does the 80 PLUS Gold badge mean for daily use?

It certifies the unit meets Gold-level efficiency targets, which lowers electricity draw, cuts heat output and lets the fan run slower or stay off at light loads.

Will this ATX unit fit my case and motherboard?

It follows the standard ATX form factor, so it mounts in any ATX-compatible chassis and connects to a 24-pin main power socket plus the usual CPU and peripheral cables.
