250 W ATX Power Supply

The KHACHIMO EFRP-250ANF is a 250 W ATX power supply built for compact desktop builds and low-power workstations. It delivers standard ATX connectivity with modern standby support for fast wake times. This unit suits systems that prioritise efficiency and quiet operation over high-wattage headroom.

80 PLUS Gold Efficiency Limits

The 80 PLUS Gold rating guarantees high efficiency at typical loads, reducing power draw, heat output and fan noise. Efficiency drops at very low or very high utilisation, so the supply performs best within its intended mid-range operating window. Builders should match the unit to actual system consumption rather than peak theoretical draw.

250 Watt Output Constraint

The single 250 W rating decides whether this unit fits a given build; it supports modest CPUs and integrated graphics but cannot power discrete graphics cards or heavy multi-drive arrays. Systems requiring more headroom must select a higher-wattage model.
