Compact SFX Power Supply

The KHACHIMO SFX unit delivers 250 W of continuous power in the small form factor required by compact chassis. It replaces FSP models rated at 180 W, 200 W and 250 W, making it suitable for space-constrained builds that still demand ATX-spec output.

Gold Efficiency and Semi-Passive Cooling

An 80 PLUS Gold rating keeps conversion losses low, reducing heat and overall power draw during typical workloads. The Zero RPM fan mode stops the fan completely at low and medium loads, while resonant LLC topology with DC-to-DC conversion minimises coil whine and supports modern standby sleep states.

SFX Form Factor Integration

The SFX footprint fits directly into cases designed for that standard without adapters. Modern standby compatibility enables rapid wake-from-sleep, and the high-efficiency design leaves more thermal headroom for surrounding components in tight layouts.

Questions about this item

How do I install this SFX power supply in my case and what step do people often miss?

Mount the unit using the four SFX screw holes, connect the 24-pin ATX, 4+4-pin CPU and any PCIe cables, then enable Modern Standby in the motherboard BIOS or the fast wake feature will not work.

What maintenance or replacement will this 250 W unit need later?

The Zero RPM fan only spins above medium load so dust builds up slowly; clean the intake grille annually and replace the fan if bearing noise appears after several years.

What limit appears first when this supply runs at sustained load?

The 250 W total-output ceiling is reached before the 80 PLUS Gold efficiency curve drops off, so the unit will hit its power limit before thermal throttling becomes an issue.
