250W ATX Power Supply for Compact Builds

The KHACHIMO FSP unit delivers 250 watts of continuous power in a standard ATX form factor. It suits small-form-factor desktops, office workstations and low-power upgrades where a full-size PSU would be oversized. Modern Standby compatibility allows near-instant wake from sleep.

80 PLUS Gold Efficiency with Zero RPM Fan

Gold certification keeps conversion losses low, reducing heat output and electricity draw during typical workloads. The Zero RPM mode stops the fan completely at low and medium loads, eliminating audible noise for silent environments. Resonant LLC topology with DC-to-DC conversion further suppresses coil whine.

ATX Connector Set for Standard Compatibility

The native ATX connector layout fits mainstream motherboards without adapters, simplifying cable routing in tight chassis. Resonant LLC and DC-to-DC design supports deeper sleep states for lower standby consumption. Builders needing multiple GPU power connectors or higher wattage for discrete graphics should consider larger units.

Questions about this item

How do I install the KHACHIMO FSP 250W ATX power supply and which step is often missed?

Mount the unit in the case, connect the 24-pin ATX and CPU power cables, then enable Modern Standby in the motherboard BIOS so the fast wake-from-sleep feature actually works.

What maintenance will this 250W Gold unit need later?

The Zero RPM fan stays off at low and medium loads, so dust builds up more slowly; clean the intake grill with compressed air once a year and listen for any bearing noise if the fan eventually spins up.

What limit appears first when this 250W supply runs under sustained load?

The 250 W continuous output ceiling is reached before the 80 PLUS Gold efficiency curve drops off, so total system draw must stay below that figure to avoid protection shutdown.
