  • Product typeATX
  • Modern Standby support for near-instant wake and low-load efficiency
  • 80 PLUS Gold certification delivers high efficiency and cooler operation
  • Zero RPM fan mode stops the fan at low loads for silent running
  • Resonant LLC topology with DC-to-DC conversion provides clean power and reduces coil whine

KHACHIMO GW-EPS1600SHA 1600W ATX Power Supply

This 1600W ATX power supply delivers high-output power for demanding multi-GPU workstations and rendering rigs. It carries 80 PLUS Gold certification for efficient operation and lower running temperatures. The unit is brand new and built with a resonant LLC topology plus DC-to-DC conversion for clean, stable voltage rails.

Suitable for multi-GPU builds.

Builders assembling multi-graphics-card machines or compute clusters will benefit from the high wattage and tight voltage regulation. Systems that only need modest power would not use this unit’s capacity and would gain no advantage from its feature set. Buyers who want a compact or lower-wattage supply should consider other options.

80 PLUS Gold efficiency with Zero RPM fan mode

The 80 PLUS Gold rating confirms high efficiency across typical loads, reducing waste heat and fan noise. A Zero RPM fan mode stops the fan completely at low and medium loads for near-silent operation. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency.

Questions about this item

Does my case need to accept an ATX power supply for this 1600W unit to fit?

Yes, the GW-EPS1600SHA follows the ATX form factor, so your chassis must support standard ATX power supplies for it to mount correctly.

Will the 80 PLUS Gold efficiency and DC-to-DC conversion still benefit a system built around older components?

The 80 PLUS Gold rating and resonant LLC topology with DC-to-DC conversion deliver high efficiency and clean power at any load, so older hardware also sees lower consumption and stable voltages.

How can I confirm the Zero RPM fan mode is actually engaging after installation?

Under light or medium workloads the cooling fan should stop spinning completely; you can verify this visually or by listening for near-silent operation when the system is idle.
