  • Product typeATX
  • Modern Standby support for near-instant wake from sleep
  • 80 PLUS Gold efficiency lowers power draw and heat

High-output ATX power supply

The KHACHIMO HFE1600 delivers 1600W of continuous power in a standard ATX form factor. It is built for workstations and high-end gaming systems that demand substantial headroom for multiple GPUs and power-hungry components. The unit carries 80 PLUS Gold certification for efficient energy conversion.

Suited for multi-GPU builds and heavy workloads

This supply fits enthusiasts running dual or triple graphics configurations and professionals driving compute-intensive tasks. Builders assembling compact ITX systems or budget-oriented PCs with modest power draw should look at lower-wattage alternatives.

Sustained delivery with quiet thermal management

Resonant LLC topology with DC-to-DC conversion maintains stable voltage regulation during extended full-load sessions while reducing coil whine. A Zero RPM fan mode keeps the unit silent at low and medium loads, and Modern Standby support enables rapid wake-from-sleep transitions.

Questions about this item

What motherboard power connectors does the HFE1600 need?

The unit follows the ATX specification, so it supplies a 24-pin main connector, 8-pin CPU connectors and the usual PCIe power plugs for graphics cards.

Will the Zero RPM fan mode still work if I keep my older components?

Yes, Zero RPM depends only on the load the PSU sees; legacy parts draw less power, so the fan will stay off at low and medium loads.

How can I confirm the 80 PLUS Gold efficiency is active after installation?

Check the system's power draw at the wall under load; it should match the Gold efficiency curve, and the fan should remain off during light use.
