KHACHIMO 855W ATX Power Supply 80 PLUS Gold

SKU CH-XV1J-7CFK4

An 855 W ATX power supply with 80 PLUS Gold efficiency, zero-RPM fan mode and Modern Standby compatibility for quiet, efficient operation

  • TypeATX
  • Modern Standby support gives extremely fast wake-from-sleep and better low-load efficiency
  • 80 PLUS Gold certification delivers high efficiency for lower power consumption, less noise, and cooler temperatures
  • Zero RPM fan mode stops the fan at low and medium loads for near-silent operation
  • Resonant LLC topology with DC-to-DC conversion provides clean power, reduces coil whine, and enables efficient sleep states
  • 855W ATX output powers demanding builds including NETAPP FAS2050 systems

NETAPP FAS2050 replacement PSU

This 855 W ATX power supply is built as a direct replacement for the NETAPP FAS2050 storage system and matches part numbers YM-3901A, CP-1266R2 and 114-00041+C4. It suits administrators who need a drop-in spare for that specific platform.

Thermals, noise and power draw

80 PLUS Gold certification means high efficiency at typical loads, which reduces waste heat and keeps internal temperatures lower. A Zero RPM fan mode stops the fan completely at low and medium loads for near-silent operation, while resonant LLC topology with DC-to-DC conversion minimises coil whine.

Modern Standby and topology benefits

Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency. The resonant LLC and DC-to-DC design delivers clean, consistent power and supports deeper, more energy-efficient sleep states without extra configuration.

Perguntas sobre este artigo

How do I install this 855W ATX unit into a NETAPP FAS2050 chassis?

Align the YM-3901A form factor with the FAS2050 bay, seat the CP-1266R2 connector fully, and torque the four captive screws evenly; the step most often missed is not pushing the connector past the detent click.

Which part will need replacement first on this 855W supply?

The cooling fan bearing is the typical wear item; Zero RPM mode reduces runtime, but plan on a fan swap after several years of continuous operation.

What limit appears first when this 855W PSU runs at sustained load?

The 80 PLUS Gold efficiency curve drops above 80 % load, so thermal throttling or fan-ramp noise becomes noticeable before the 855 W rating is exceeded.
