KHACHIMO Alienware R8R7 850W Power Supply

SKU CH-F3GX-WVB6H

An 850W ATX power supply with 80 PLUS Gold efficiency, Zero RPM fan mode and Modern Standby compatibility for quiet, low-load operation

  • TypeATX
  • Modern Standby support for extremely fast wake-from-sleep times
  • 80 PLUS Gold certified for lower power consumption and cooler operation
  • Zero RPM fan mode stops the fan at low and medium loads for near-silent running
  • Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power and reduces coil whine
  • ATX form factor fits standard desktop cases

Compatible Alienware Power Supply

The KHACHIMO Alienware R8R7 850W unit replaces the D850EF-00, D850EF-01, NJVDN, HU850EF-00, HU850EF-01, HK950-11PP and HK950-51PP models in compatible Dell Alienware desktops. It delivers 850 watts through a standard ATX form factor for high-performance systems.

Installation Notes

The ATX layout matches the original chassis mounting points and connector arrangement for a direct swap. Zero RPM fan mode eliminates noise at low and medium loads, while the resonant LLC topology with DC-to-DC conversion reduces coil whine. Modern Standby compatibility enables extremely fast wake-from-sleep times.

80 PLUS Gold Efficiency

Certified 80 PLUS Gold operation lowers power consumption, noise and operating temperatures under typical loads. This efficiency rating is the primary specification that determines suitability for energy-conscious builds. Buyers needing higher wattage or a different form factor should look elsewhere.

Questions about this item

How do I verify the 850W power supply is operating correctly after installation?

Check that the system boots reliably, the 80 PLUS Gold efficiency rating is reflected in lower power draw under load, and the Zero RPM fan mode keeps the fan off at low and medium loads for near-silent operation.

What comes with the KHACHIMO Alienware R8R7 unit and what must be purchased separately?

The power supply itself is included; standard ATX power cables for motherboard, CPU, GPU and drives are typically bundled, while any specialised Alienware proprietary cables or mounting brackets for specific chassis models would need to be sourced separately.

Which compatible part number should I select among D850EF-00, D850EF-01, NJVDN, HU850EF-00, HU850EF-01, HK950-11PP and HK950-51PP?

All listed part numbers reference the same 850W ATX design with Modern Standby, 80 PLUS Gold, Zero RPM fan mode and Resonant LLC topology; choose the exact code that matches your Alienware service tag or chassis revision for guaranteed fit.
