KHACHIMO 820W ATX Power Supply 80 PLUS Gold

SKU CH-CVSQ-FF235

An 820 W ATX unit with 80 PLUS Gold efficiency, Modern Standby support, zero-RPM fan mode and resonant LLC topology with DC-to-DC conversion for clean, quiet power

  • 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, consistent power and reduces coil whine
  • ATX form factor 820W unit fits standard desktop builds and supports modern sleep states

What this PSU delivers

The KHACHIMO 820W ATX unit is built for desktop builders who need 80 PLUS Gold efficiency and Modern Standby support for rapid wake times. Its resonant LLC topology with DC-to-DC conversion supplies steady rails and helps reduce coil whine. The zero RPM fan mode keeps the system near-silent at low and medium loads.

Check before ordering

Verify that your chassis accepts a standard ATX power supply and that your motherboard uses the usual 24-pin ATX and 8-pin EPS connectors. Confirm the unit’s physical length fits your case and that the cable set matches your GPU and storage needs. The model codes YM-2821A, YM-2821ACR and YM-2821ABR identify this exact unit.

Sustained-load behaviour

Under continuous demand the 80 PLUS Gold rating ensures high efficiency, limiting waste heat and keeping internal temperatures lower. The resonant LLC design maintains tight voltage regulation across the rails during extended sessions. The fan remains off until the thermal threshold is reached, then spins up only as needed.
