  • TypeATX
  • Modern Standby support gives extremely fast wake-from-sleep and better low-load efficiency
  • 80 PLUS Gold certification delivers high efficiency for lower power consumption, less noise, and cooler temperatures
  • Zero RPM fan mode stops the fan at low and medium loads for near-silent operation
  • Resonant LLC topology with DC-to-DC conversion provides clean, consistent power and reduces coil whine
  • 250 W ATX power supply in a compact 1U form factor for space-constrained builds

What this power supply delivers

The KHACHIMO FSP250-601U is a new 250 W ATX unit built for compact systems that value efficiency and quiet operation. It carries 80 PLUS Gold certification and supports Modern Standby for rapid wake-from-sleep transitions. Resonant LLC topology with DC-to-DC conversion supplies clean, stable power while reducing coil whine.

Who benefits and who should look elsewhere

Builders of small-form-factor PCs, home-theatre rigs, or always-on servers will appreciate the Zero RPM fan mode that halts the fan at low and medium loads. Buyers who need more storage drives, multiple high-power graphics cards, or components that draw beyond 250 W must choose a higher-capacity unit instead.

The specification that decides fit

The 250 W rated output is the single figure that determines whether this supply can power your complete build; add the peak draw of every component and confirm the total stays below this limit.
