KHACHIMO SS-250SU ATX Power Supply 250W

The KHACHIMO SS-250SU is an ATX form factor power supply rated at 250W. It is intended for basic desktop builds or as a replacement unit in systems with modest power requirements. The unit is supplied new and has been tested working by the manufacturer. It suits users who need a straightforward, standard ATX power source without additional features.

Practical limits of the ATX standard

The ATX form factor defines physical dimensions and connector layouts that fit standard desktop chassis and motherboards. A 250W rating sets the maximum combined output across all rails, which restricts the number and type of components the supply can support. Builders must ensure the total system draw stays within this limit. The standard does not guarantee compatibility with high-power graphics cards or multi-drive arrays.

250W total output

The single specification that decides suitability is the 250W total output. This figure determines whether the unit can deliver enough power for the intended CPU, graphics card, storage devices and peripherals. Systems requiring more headroom will need a higher-rated supply. Buyers who want more power for demanding components should look for a unit with a higher wattage rating.
