KHACHIMO

KHACHIMO FSP1600-29FM 1600W Power Supply

SKU CH-4TQZ-X685V

A 1600 W ATX power supply with 80 PLUS Gold efficiency, Modern Standby compatibility, Zero RPM fan mode and resonant LLC topology with DC-to-DC conversion for clean power delivery

  • TypeATX
  • Faster wake-from-sleep with Modern Standby support
  • Lower power draw and heat thanks to 80 PLUS Gold efficiency
  • Near-silent operation at typical loads via Zero RPM fan mode
  • Clean, stable power delivery through resonant LLC with DC-to-DC conversion
  • Reduced coil whine for quieter system operation

High-capacity ATX power supply

The KHACHIMO FSP1600-29FM delivers 1600 W of continuous power in a standard ATX form factor. It is built for workstations and high-end desktop systems that draw heavy loads from multiple GPUs or dense storage arrays. The unit carries 80 PLUS Gold certification for efficient conversion across the load range. Builders who need a lower-wattage unit for a single-GPU gaming rig should look elsewhere.

Gold efficiency and silent fan mode

80 PLUS Gold certification means less waste heat and lower electricity draw at typical loads. The Zero RPM fan mode stops the fan completely at low and medium loads, removing audible noise during idle or light work. Resonant LLC topology with DC-to-DC conversion keeps voltage regulation tight and reduces coil whine. Modern Standby support allows the system to wake from sleep almost instantly.

Standard ATX installation

The supply fits any ATX-compliant case and uses the usual 24-pin, EPS and PCIe connectors expected by modern motherboards and graphics cards. Modular cabling lets you attach only the leads the build requires, simplifying cable routing. The deep chassis may conflict with tight clearance behind the motherboard tray in some compact cases. Verify case depth and connector reach before ordering.

Questions about this item

How often will the cooling fan need replacement under continuous load?

The Zero RPM Fan Mode keeps the fan off at low and medium loads, so the fan only spins when higher output is required, extending its service life.

What limit appears first when the unit runs at full 1600W output for extended periods?

The 80 PLUS Gold certification guarantees high efficiency at typical loads, so thermal limits are reached before electrical limits during sustained maximum output.

How much noise and heat does the power supply produce when running all day at typical loads?

Zero RPM Fan Mode stops the fan entirely at low and medium loads for near-silent operation, while 80 PLUS Gold efficiency reduces waste heat and keeps temperatures lower.
