KHACHIMO PowerEdge R905 1100W Power Supply

SKU CH-A12Z-VNEER

A new 1100 W ATX power supply with 80 PLUS Gold efficiency, Modern Standby support, Zero RPM fan mode and resonant LLC topology for quiet, stable power delivery

  • TypeATX
  • Faster wake-from-sleep and better low-load efficiency with Modern Standby support
  • Lower power draw, less noise and cooler running thanks to 80 PLUS Gold efficiency
  • Near-silent operation at low and medium loads through Zero RPM fan mode
  • Clean, consistent power delivery and reduced coil whine via resonant LLC with DC-to-DC conversion
  • 1100W ATX power supply built for PowerEdge R905 systems

High-Capacity ATX Power Supply

The KHACHIMO PowerEdge R905 delivers 1100W of continuous power in a standard ATX form factor. It is built for high-performance workstations and servers that demand stable, high-wattage output. The unit carries 80 PLUS Gold certification for verified efficiency at typical loads.

Sustained Load Efficiency and Acoustics

Under continuous demand the Gold-rated design maintains high conversion efficiency, reducing waste heat and keeping internal temperatures lower. The resonant LLC topology with DC-to-DC conversion supplies clean, consistent voltage rails during extended operation. A zero-RPM fan mode stops the cooling fan completely at low and medium loads for silent running.

Modern Standby and Interface Limits

Modern Standby compatibility allows extremely fast wake-from-sleep transitions and improved low-load efficiency for supported platforms. The ATX interface defines the physical and electrical connection limits for motherboard power delivery. Efficiency certification is measured up to the 80 PLUS Gold standard without higher-tier guarantees.

Questions sur cet article

How loud and hot does the 1100W unit get when it runs all day?

The 80 PLUS Gold rating keeps efficiency high, so waste heat and fan speed stay low. A Zero RPM mode stops the fan completely at light and medium loads for near-silent operation, while the LLC resonant topology reduces coil whine.

What must my system already have for this supply to work?

It follows the ATX form factor and is Modern Standby compatible, so it fits standard ATX cases and works with motherboards that support the Modern Standby sleep state.

Will the R905 1100W cause issues with older components I want to keep?

The DC-to-DC conversion and LLC resonant topology deliver clean, consistent power, which helps older parts run stably and enables deeper, more efficient sleep states.
