A 1600W ATX power supply with 80 PLUS Gold efficiency, Zero RPM fan mode and Modern Standby support

  • Product typeATX
  • Fast wake and better low-load efficiency with Modern Standby support
  • High efficiency lowers consumption, noise and heat with 80 PLUS Gold certification
  • Near-silent operation at low and medium loads via Zero RPM fan mode
  • Clean, consistent power and reduced coil whine from resonant LLC with DC-to-DC conversion
  • Enables energy-efficient sleep states through advanced topology design

KHACHIMO 1600W ATX Power Supply

The KHACHIMO RX4770M1 delivers 1600W of continuous power in a standard ATX form factor. It targets workstations and high-end desktops that demand substantial headroom for multi-GPU configurations or heavy compute loads. Builders who need more than this unit’s rated output will have to look elsewhere.

80 PLUS Gold Efficiency Limits

Certified at 80 PLUS Gold, the unit meets strict efficiency thresholds at typical loads to reduce waste heat and electricity draw. Modern Standby compatibility allows extremely fast wake-from-sleep transitions while maintaining low idle consumption. Systems that cannot utilise Modern Standby states will not benefit from this feature.

Resonant LLC Topology and Zero RPM Fan

A resonant LLC topology with DC-to-DC conversion supplies clean, consistent voltage and helps minimise coil whine during operation. Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent running. The fan will engage automatically once thermal thresholds are exceeded.

Questions about this item

Which capacity should I choose for a high-end build?

The 1600W unit suits systems with dual GPUs, heavy overclocking or workstation-class loads that demand sustained high output.

What does the 80 PLUS Gold rating deliver in daily use?

It means the supply runs at high efficiency across typical loads, lowering electricity draw, reducing heat and keeping fan noise down.

What does the ATX form factor limit in practice?

ATX dimensions dictate case clearance and cable routing space, so verify your chassis supports standard ATX length before fitting this 1600W model.
