SKU CH-T4AG-PTPTB

ATX 650W 80 PLUS Gold power supply with Modern Standby support, zero-RPM fan mode and resonant LLC topology for quiet, efficient operation

  • TypeATX
  • Fast wake-from-sleep with Modern Standby support
  • High efficiency 80 PLUS Gold certification reduces power draw
  • Silent Zero RPM fan mode at low loads
  • Clean power delivery via Resonant LLC with DC-to-DC
  • 650W output for reliable system performance

650W ATX power supply for modern PCs

The KHACHIMO DPS-650QB A delivers 650W of continuous power through an ATX form factor. It suits builders assembling new systems that require 80 PLUS Gold efficiency and Modern Standby compatibility for rapid wake-from-sleep behaviour.

Sustained-load behaviour with Zero RPM mode

Under prolonged load the resonant LLC topology with DC-to-DC conversion maintains clean, consistent output while reducing coil whine. The cooling fan remains off at low and medium loads for near-silent operation, spinning up only when thermal conditions demand active airflow.

Efficiency and sleep-state limits

80 PLUS Gold certification confirms high efficiency across typical operating ranges, lowering power draw, noise and temperature. Modern Standby support enables deeper, more energy-efficient sleep states, though the unit cannot accelerate wake times beyond the platform firmware capabilities.

Questions sur cet article

How quiet is the 650W unit when the system runs all day?

The 80 PLUS Gold efficiency and Zero RPM Fan Mode keep the fan off at low and medium loads, so the supply stays near-silent during typical all-day use.

What must my build already have for this ATX power supply to work?

Your case needs an ATX PSU bay and your motherboard must accept standard ATX power connectors; the unit then delivers 650W through its native cabling.

Will this supply run stably with older components I keep in the new build?

Modern Standby compatibility and the resonant LLC topology with DC-to-DC conversion provide clean, consistent power that supports energy-efficient sleep states on legacy hardware.
