Compact 250W ATX power supply

The KHACHIMO P09003 is a 250 watt ATX unit designed for small-form-factor PCs and office systems that need reliable power without excess capacity. It suits builders assembling low-power desktops, media centres or secondary workstations where space and efficiency matter more than high wattage headroom.

80 PLUS Gold efficiency with silent fan

Gold-rated efficiency keeps consumption, heat and noise low during everyday use. The Zero RPM fan mode stops the cooling fan entirely at light and medium loads, while the resonant LLC topology with DC-to-DC conversion delivers stable rails and reduces coil whine for quieter operation.

Modern Standby support for instant wake

Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency, making this supply a good match for systems that spend long periods in connected standby. Builders who need more than 250 watts for discrete graphics or heavy multi-core workloads should look at higher-capacity units.

Questions about this item

What ATX standard does the 250 W unit follow, and what practical limit does it set?

The PSU is built to the ATX form factor and delivers a continuous 250 W output, which caps the total power available to all components combined.

What physical space and mounting pattern does the P09003 require in the case?

It uses the standard ATX footprint with four rear mounting screws, so it fits any case designed for a regular ATX power supply.

How is the PSU installed, and which step do builders often miss?

Secure the unit with four screws, connect the 24-pin motherboard and 4/8-pin CPU cables, then route the remaining modular leads; the step most often missed is plugging in the CPU power connector near the socket.
