KHACHIMO 300W Power Supply FSP300-10TAA

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.
