Compact 1U silver power supply unit with rear fan grille and side ventilation slots

KHACHIMO

KHACHIMO APFC F0 80+ Gold 1U 350W power supply

SKU CH-ZBDN-3BXPG

Compact 1U ATX power supply delivering 350 W with 80 PLUS Gold efficiency, Modern Standby support, zero-RPM fan mode and resonant LLC topology for clean, quiet power

  • TypeATX
  • 80 PLUS Gold efficiency lowers power draw and heat
  • Zero RPM fan mode stops the fan at low and medium loads for silent running
  • Modern Standby support gives extremely fast wake-from-sleep times and better low-load efficiency
  • Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power and reduces coil whine
  • 1U form factor fits NSC-800, NSC-810 and NSC-810A chassis with 350 W output

Compact server power supply

The KHACHIMO APFC F0 is a 350 W ATX unit built for 1U rackmount chassis such as the NSC-800, NSC-810 and NSC-810A. It targets system integrators and IT managers who need reliable, efficient power in space-constrained servers or workstations.

Replaces older 1U units

The 80 PLUS Gold rating and Modern Standby compatibility make the upgrade worthwhile when an existing supply lacks low-load efficiency or fast wake-from-sleep support. It is not suited for builds that require higher wattage or redundant power modules.

Sustained-load behaviour

Resonant LLC topology with DC-to-DC conversion delivers clean, consistent output under continuous demand while reducing coil whine. Zero RPM fan mode keeps the unit silent at low and medium loads, and the fan engages only when thermal conditions require active cooling.

Questions about this item

Will the 1U height fit the NSC-800, NSC-810 and NSC-810A chassis?

The 1U form factor matches the NSC-800, NSC-810 and NSC-810A chassis, and the ATX connector layout aligns with their standard motherboard headers.

Which cable must be seated first so that Modern Standby wake-up works reliably?

Insert the main 24-pin ATX connector fully before the 4-pin CPU power cable; if the 24-pin is loose the low-power signalling fails.

When should the 350 W unit be replaced to keep 80 PLUS Gold efficiency?

Plan replacement after five to seven years of continuous use; ageing capacitors gradually reduce efficiency and can prevent Modern Standby from entering its lowest sleep state.
