Silver rectangular ATX power supply unit with ventilation grille and fan visible

KHACHIMO

KHACHIMO FSP300-601U / FSP350-601UA 300W 350W ATX power supply

SKU CH-ANBC-AREQC

ATX power supply delivering 300W or 350W with 80 PLUS Gold efficiency, Modern Standby support, Zero RPM fan mode and LLC resonant topology with DC-to-DC conversion

  • TypeATX
  • 80 PLUS Gold efficiency cuts power draw and heat
  • Zero RPM fan mode stops the fan at low loads for silent running
  • Modern Standby support gives faster wake times and better idle efficiency
  • Resonant LLC with DC-to-DC conversion delivers stable power and reduces coil whine
  • ATX form factor fits standard desktop and 1U server chassis

1U ATX power supply for compact builds

The KHACHIMO FSP300-601U and FSP350-601UA deliver 300W or 350W in a 1U ATX form factor suited to rackmount servers, slim workstations or small-form-factor PCs where height is constrained. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. An 80 PLUS Gold rating means high efficiency operation for lower power consumption, less noise and cooler temperatures.

Verify 1U clearance and Modern Standby support

Confirm the chassis can accept a 1U ATX supply and that the motherboard implements Modern Standby to use the fast wake and low-load efficiency benefits. The resonant LLC topology with DC-to-DC conversion provides clean, consistent power and reduces coil whine, but the board must support the sleep states it enables. Zero RPM fan mode stops the fan at low and medium loads for near-silent operation, so airflow at higher loads depends on case ventilation.

Replaces older 1U units without Gold efficiency

This supply upgrades from 1U ATX units that lack 80 PLUS Gold certification, Zero RPM fan mode or Modern Standby support. The jump is worth it when you need quieter idle operation, lower standby power draw and cleaner power delivery for energy-efficient sleep states. Builders who need higher wattage than 350W or a standard ATX height unit should look elsewhere.

Perguntas sobre este artigo

Does the box include cables or mounting hardware, or must they be purchased separately?

The unit ships as a bare power supply; cables and mounting screws are not included and must be sourced separately.

Which wattage variant should I pick between the 300W and 350W models?

Choose the 350W model if your build draws closer to that limit; the 300W model suits lower-power systems and both share the same feature set.

What does the 80 PLUS Gold rating mean for everyday use?

It guarantees at least 80% efficiency at typical loads, reducing electricity draw, heat output and fan noise compared with lower-rated units.
