KHACHIMO

KHACHIMO 750W Power Supply DPS-750AB-14A

SKU CH-XV1R-A6DYA

An ATX 750 W power supply with 80 PLUS Gold efficiency, zero-RPM fan mode and Modern Standby compatibility for quiet, low-energy operation

  • TypeATX
  • Modern Standby support for extremely fast wake-from-sleep
  • 80 PLUS Gold certification for high efficiency and cooler operation
  • Zero RPM fan mode stops the fan at low loads for near-silent running
  • Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power
  • ATX form factor fits standard desktop chassis

Server Compatibility

The KHACHIMO DPS-750AB-14A is a 750W ATX power supply designed for specific server platforms including X3550M4, X3650M4 and X3850X6 systems. It delivers reliable power for enterprise workloads and carries 80 PLUS Gold certification for efficient operation.

Target Use Cases

This unit suits administrators maintaining compatible rack servers who need a direct replacement with modern standby support. Builders assembling custom workstations or standard desktop PCs should look elsewhere as the form factor and connectors are tailored to the listed server models.

Sustained Load Behaviour

Under continuous demand the resonant LLC topology with DC-to-DC conversion maintains stable voltage regulation while reducing coil whine. The zero RPM fan mode remains inactive during heavy loads, allowing active cooling to manage temperatures without acoustic compromise.

Questions about this item

Does the 750W PSU need a standard ATX motherboard connector to work?

Yes, the unit is an ATX-type power supply, so it requires a motherboard with the matching 24-pin ATX power socket and corresponding CPU/EPS connectors.

Will the Zero RPM fan mode still function if I keep an older graphics card that draws more power at idle?

The fan stops only at low and medium loads; an older GPU that idles at higher wattage may keep the load above the Zero RPM threshold, so the fan would stay on.

How can I verify the 80 PLUS Gold efficiency is active after installation?

Monitor system power draw at the wall while the PC idles and under load; a Gold-rated unit should show notably lower AC input versus DC output compared with a non-rated supply.
