  • Product typeATX
  • Faster wake from sleep with Modern Standby support
  • Lower power draw and heat with 80 PLUS Gold efficiency
  • Silent low-load operation via Zero RPM fan mode
  • Clean, stable output from resonant LLC with DC-to-DC conversion
  • High 1600W capacity for demanding ATX systems

High-Capacity ATX Power Supply

The KHACHIMO E6000 delivers 1600W of continuous power in a standard ATX form factor. It targets workstations and servers that demand high output with certified efficiency. The unit carries 80 PLUS Gold certification to reduce waste heat and operating cost. Modern Standby compatibility ensures rapid wake times and improved low-load efficiency.

Suitable for High-Draw Systems

This supply suits builds running multiple GPUs, high-core-count CPUs, or dense storage arrays that approach its rated output. The Zero RPM fan mode keeps acoustics minimal during idle or light workloads. It is not intended for compact cases that cannot accommodate a full-size ATX unit. Buyers needing significantly lower maximum power should consider smaller alternatives.

Integration and Build Impact

The ATX design fits standard mounting points and cable routing channels in compatible chassis. Resonant LLC topology with DC-to-DC conversion provides stable voltage rails for sensitive components. High efficiency at typical loads frees thermal headroom inside the case. Ensure the chosen enclosure supports the physical length and airflow requirements of a high-wattage ATX power supply.

Questions about this item

What motherboard power connectors must my board provide for the EPW1600-12A to work?

The unit follows the ATX specification, so your motherboard needs the standard 24-pin main connector, an 8-pin (or 4+4-pin) CPU power connector, and any PCIe connectors your graphics card requires.

Can I keep using my older ATX 2.x motherboard with this Modern Standby compatible supply?

Yes, the power supply is backward-compatible with earlier ATX boards; Modern Standby features simply remain inactive on platforms that do not support them.

How can I confirm the Zero RPM fan mode is active after I build the system?

With the system at idle or light load, listen for the PSU fan — it should be completely still; you can also watch the fan-speed reading in your motherboard’s hardware monitor drop to 0 RPM.
