KHACHIMO 260W ATX power supply for compact systems

The KHACHIMO SP262-1S is a 260-watt ATX switching power supply built for 1U and other space-constrained chassis. It targets builders assembling small-form-factor PCs, embedded appliances or replacement units where a standard ATX footprint will not fit.

Thermals noise and power draw

80 PLUS Gold certification delivers high efficiency across the load range, reducing waste heat and overall power consumption. A Zero RPM fan mode stops the cooling fan completely at low and medium loads, enabling near-silent operation during idle or light workloads.

Resonant LLC topology and Modern Standby support

Resonant LLC topology with DC-to-DC conversion supplies clean, consistent power while reducing coil whine and supporting deeper, more energy-efficient sleep states. Modern Standby compatibility allows extremely fast wake-from-sleep times and improved low-load efficiency for always-connected workflows.

Questions about this item

How do I install this 1U 260W ATX power supply in a rackmount chassis and what step is often missed?

Slide the unit into the 1U bay, secure the four mounting screws, then connect the 24-pin ATX and CPU power cables; the step often missed is plugging in the Modern Standby signal cable so the fast wake-from-sleep feature actually works.

What maintenance will this SP262-1S need over its lifespan?

The Zero RPM fan stays off at low and medium loads, so dust buildup is minimal; simply vacuum the intake grille once a year and the Gold-rated efficiency keeps internal temperatures low, reducing electrolyte aging in the capacitors.

What is the first limit reached when this 260W supply runs at sustained full load?

The 260W continuous output ceiling is the hard limit; the Resonant LLC topology with DC-to-DC conversion delivers clean power up to that point, but exceeding it triggers over-power protection and shuts the unit down.
