KHACHIMO 650W power supply DPS-650UB C 24P+22P 80 PLUS Gold

SKU CH-F3JS-8QJV4

A 650 W ATX power supply with 80 PLUS Gold efficiency, 24-pin and 22-pin connectors, zero-RPM fan mode and resonant LLC topology for quiet, efficient operation

  • TypeATX
  • Modern Standby support enables faster wake-from-sleep
  • 80 PLUS Gold certification delivers high efficiency for lower power draw and cooler running
  • 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, consistent power and reduces coil whine
  • 24-pin and 22-pin ATX connectors supply 650 W to compatible systems

1U 650W ATX power supply

This 1U form-factor ATX power supply delivers 650W of continuous power through a 24-pin and a 22-pin connector. It is built for compact servers and workstations that require standard ATX voltages in a slim chassis. The unit is new and carries 80 PLUS Gold certification for verified efficiency.

Sustained-load behaviour

The resonant LLC topology with DC-to-DC conversion maintains clean, consistent voltage regulation during extended workloads. This design reduces ripple and coil whine while supporting modern energy-efficient sleep states without voltage drift. The 80 PLUS Gold rating confirms high efficiency across typical server load ranges.

Thermals, noise and power draw

Zero RPM fan mode stops the cooling fan completely at low and medium loads for near-silent operation. 80 PLUS Gold efficiency lowers waste heat, keeping internal temperatures reduced during normal use. Modern Standby compatibility enables extremely fast wake-from-sleep with minimal idle power consumption.

Questions about this item

How loud does the 650W unit run during all-day use?

The 80 PLUS Gold certification and Zero RPM fan mode keep the unit silent at low and medium loads, while the LLC resonant topology reduces coil whine for quieter sustained operation.

Which motherboard connectors must my board already provide for this PSU?

The unit supplies a 24-pin ATX connector and a 22-pin auxiliary connector, so your motherboard needs matching 24-pin and 22-pin sockets.

Will this 650W supply work reliably with older components I plan to keep?

The DC-to-DC conversion and resonant LLC topology deliver clean, consistent power that is compatible with legacy hardware while supporting modern sleep states.
