KHACHIMO DPS-800NB B 800W power supply

SKU CH-TYN4-M4R30

An 800 W ATX power supply with 80 PLUS Gold efficiency, zero-RPM fan mode and resonant LLC topology for quiet, stable power

  • TypeATX
  • Modern Standby compatibility for near-instant wake from sleep
  • 80 PLUS Gold certification cuts power draw and heat
  • Zero RPM fan mode stops the fan at low load for silence
  • Resonant LLC topology with DC-to-DC conversion delivers clean power and reduces coil whine
  • 800 W ATX output handles demanding multi-GPU builds

Modern Standby Power Supply

This KHACHIMO 800W unit is built for desktop PCs that require fast wake-from-sleep response and efficient low-load operation. It suits builders who want an ATX form-factor supply with certified gold-level efficiency. The platform targets systems where quiet idle behaviour and modern sleep-state support are priorities. It is not intended for servers or workstations that demand redundant or hot-swap power modules.

ATX Form Factor Integration

The supply fits standard ATX mounting points and delivers 800W through a DC-to-DC conversion stage that keeps voltage regulation tight across the rails. Resonant LLC topology reduces coil whine and enables deeper sleep states without extra wiring. Zero RPM fan mode allows the cooler to stay off at low and medium loads, freeing acoustic headroom for other components. Builders needing non-ATX footprints or higher peak wattage must look elsewhere.

Sustained Load Behaviour

Under continuous demand the 80 PLUS Gold rating ensures high efficiency, limiting waste heat and keeping internal temperatures lower than less certified units. The fan remains off until thermal thresholds rise, then spins up only as needed for near-silent ramp-up. Resonant LLC circuitry maintains clean power delivery during extended sessions, reducing ripple that can stress sensitive components. Systems requiring constant maximum output beyond the rated capacity should consider a larger unit.

Questions sur cet article

What is the first limit reached during sustained full-load operation?

The 800 W rated output is the ceiling; the unit will trigger over-power protection if that level is exceeded continuously.

How does fan noise and heat behave when the supply runs all day?

Zero RPM mode keeps the fan off at low and medium loads, and 80 PLUS Gold efficiency reduces waste heat, so noise and temperatures stay low during extended use.

What existing hardware must be present for this supply to work?

A standard ATX motherboard with a 24-pin main connector and the required CPU and GPU power cables is needed.
