KHACHIMO DS1050-3 1050W ATX power supply

SKU CH-WKDB-J3F8E

ATX power supply delivering 1050W with 80 PLUS Gold efficiency, Modern Standby support, zero-RPM fan mode and LLC resonant DC-to-DC topology for clean, quiet power

  • TypeATX
  • Modern Standby support enables rapid wake-from-sleep and improved low-load efficiency
  • 80 PLUS Gold certification delivers high efficiency for lower power draw, less noise 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, stable power and reduces coil whine
  • 1050W ATX output supplies ample power for demanding system builds

Power Supply for Modern Standby Systems

The KHACHIMO DS1050-3 is a 1050W ATX unit built for PCs that use Modern Standby sleep states. Its 80 PLUS Gold certification confirms high efficiency across typical loads, reducing waste heat and electricity draw. The resonant LLC topology with DC-to-DC conversion delivers stable voltage rails for dependable component operation. Builders needing a different form factor or lower maximum output should look elsewhere.

Thermals and Acoustics at Typical Loads

A Zero RPM fan mode stops the cooling fan completely during low and medium workloads, keeping the system nearly silent. The Gold-rated efficiency lowers internal heat generation, which helps the fan stay off longer and keeps case temperatures down. Resonant LLC topology with DC-to-DC conversion also reduces coil whine for a quieter electrical profile. Users who require active airflow at all times will not get it here.

Behaviour Under Sustained Load

The resonant LLC topology with DC-to-DC conversion maintains clean, consistent power delivery during extended high-demand periods. Gold-level efficiency continues to limit excess heat and power waste when the unit runs closer to its 1050W rating. Modern Standby compatibility ensures the supply transitions smoothly back to low-power states after heavy sessions. Systems needing redundancy or hot-swap capability are not supported.

Questions sur cet article

How do I connect the KHACHIMO DS1050-3 to my motherboard and graphics card using the ATX interface?

Mount the unit in the case with four screws, plug the 24-pin ATX cable into the motherboard, attach the CPU power connector near the socket, and connect PCIe cables to the graphics card; the step often missed is seating every modular plug fully until it clicks.

What maintenance will the 80 PLUS Gold certified DS1050-3 need over its lifetime?

Clean dust from the intake grille and fan blades once or twice a year using compressed air; the Zero RPM Fan Mode means the fan stops at low load, so dust builds up more slowly than on always-spinning units.

At what point does the 1050W DS1050-3 hit its thermal limit during sustained full-load operation?

The protection circuit will shut the unit down if internal temperatures exceed the safe threshold, which occurs first when continuous output approaches the rated 1050W in a poorly ventilated case.
