ATX power supply for replacement builds

This KHACHIMO unit is an ATX power supply rated at 252W and built to fit standard chassis layouts. It suits system integrators and DIY builders who need a direct replacement for a DPS-252FB model. The 4.2V rails are rated at 50A and 60A to match the original specification. It is not for systems that require a higher total wattage or a different form factor.

80 PLUS Gold efficiency rating

The single specification that decides fit is the 80 PLUS Gold certification, which guarantees high efficiency across typical load ranges. This efficiency level lowers power draw, reduces waste heat and helps keep acoustic output down. Builders who need a certified Gold unit for compliance or thermal reasons should verify this rating matches their requirement. Units without this certification will not meet the same efficiency target.

Zero RPM fan mode under sustained load

Under sustained low and medium loads the cooling fan remains completely stationary, eliminating mechanical noise during long work sessions. Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power and reduces coil whine when the system is stressed for extended periods. Modern Standby compatibility ensures rapid wake-from-sleep without voltage instability. Heavy continuous loads that exceed the fan-off threshold will engage active cooling.

Questions about this item

What does the 252W rating mean when this PSU is installed in a PC?

It indicates the maximum continuous power the unit can deliver across all rails while staying within its 80 PLUS Gold efficiency target.

How does the ATX form factor limit or define the connectors available on this unit?

ATX defines the physical mounting dimensions and the standard 24-pin, EPS and peripheral connector layout this supply uses.

What clearance or mounting points does this power supply need inside a case?

It fits any case with a standard ATX PSU bay and uses the four rear mounting holes defined by the ATX specification.
