250 W ATX power supply for compact builds

The KHACHIMO FSP250-50BMV is a 250 W ATX unit designed for small-form-factor PCs, office workstations and low-power home servers. It delivers enough headroom for modern standby sleep states while keeping the physical footprint minimal. Builders who need a reliable, efficient supply for integrated graphics or entry-level discrete cards will find it a practical fit.

ATX form factor with modern standby support

The standard ATX dimensions let it drop into most tower and slimline chassis without adapter brackets. Modern standby compatibility means the system wakes from sleep almost instantly and draws very little power while idle. Zero RPM fan mode stops the fan completely at low and medium loads, so the supply adds no audible noise during typical desktop use.

80 PLUS Gold efficiency with 250 W continuous output

Gold certification keeps waste heat and electricity costs low across the load range. The resonant LLC topology with DC-to-DC conversion provides tight voltage regulation for stable CPU and GPU operation. At sustained loads above 250 W the unit will hit its limit, so systems with high-end graphics cards or multiple drives should look for a higher-wattage model.

Questions about this item

What limits the KHACHIMO FSP250-50BMV when it runs at full load for hours?

The 250 W rated output is the ceiling; sustained loads above that will trigger protection or shutdown.

How loud and hot does the unit get during all-day operation?

Zero RPM mode stops the fan at low and medium loads for silent running, while 80 PLUS Gold efficiency keeps waste heat and noise low even at higher loads.

Which motherboard power connectors must my build already provide for this PSU to work?

It uses the standard ATX 24-pin main connector plus a 4-pin or 8-pin CPU power plug — both must be present on the motherboard.
