KHACHIMO

KHACHIMO QFX10008 10016 3000W power supply

SKU CH-4G5H-YBTNS

A 3000W ATX power supply with 80 PLUS Gold efficiency, Zero RPM fan mode and Modern Standby compatibility for fast wake times

  • TypeATX
  • Faster wake from sleep with Modern Standby support
  • 80 PLUS Gold efficiency cuts power draw and heat
  • Fan stops at low loads for silent running
  • LLC resonant topology with DC-to-DC delivers clean power
  • 3000W output fits QFX10008 and 10016 chassis

3000W server power supply

The KHACHIMO QFX10008 10016 is a 3000W ATX power supply built to replace the DPS-2850AB A and QFX10000-PWR-AC-A units in Juniper QFX10000 switches. It delivers 80 PLUS Gold certified efficiency and supports Modern Standby for rapid wake-from-sleep transitions. This unit suits network administrators upgrading or maintaining high-density switching infrastructure.

Sustained-load behaviour

Resonant LLC topology with DC-to-DC conversion provides clean, consistent power across extended operating periods while reducing coil whine. The Zero RPM fan mode keeps the cooling fan off at low and medium loads, lowering acoustic output during routine operation. Gold-rated efficiency curbs waste heat and power draw even when the chassis runs continuously at significant capacity.

Replacement scope and upgrade value

This supply directly replaces the 740-049388 and QFX10000-PWR-AC models without requiring cabling changes. The efficiency and acoustic gains justify the swap when older units show increased fan noise, higher thermal output, or degraded efficiency under constant load. It is not suited for standard desktop ATX builds or workstations that lack the matching chassis connector and airflow design.

Questions about this item

How loud is the KHACHIMO QFX10008 10016 3000W power supply under continuous all-day load?

The 80 PLUS Gold certification and Zero RPM Fan Mode keep noise low; at low and medium loads the fan stops completely, while high efficiency reduces heat output during sustained operation.

What existing hardware is required to install this 3000W ATX unit?

A standard ATX case with sufficient clearance, a motherboard with 24-pin ATX and EPS power connectors, and an AC mains cable rated for the 3000W draw are needed for installation.

Will the KHACHIMO QFX10008 10016 work reliably with older components such as a DPS-2850AB A or QFX10000-PWR-AC-A?

Yes, the unit is listed as a direct replacement for DPS-2850AB A, QFX10000-PWR-AC and QFX10000-PWR-AC-A (part 740-049388), so it matches the pin-out and power delivery of those legacy supplies.
