800W ATX Power Supply for Modern Standby Builds

The KHACHIMO DPS-800AB-62A delivers 800W of continuous power in a standard ATX form factor. It carries 80 PLUS Gold certification for high efficiency across typical loads. The unit supports Modern Standby, enabling extremely fast wake-from-sleep times and improved low-load efficiency. Resonant LLC topology with DC-to-DC conversion provides clean, consistent power output.

Suits Builds Prioritising Quiet Operation

This unit suits users who value near-silent operation at low and medium loads thanks to its Zero RPM fan mode. It also suits builders enabling modern sleep states, as the topology supports more energy-efficient sleep transitions. Buyers needing higher wattage for multi-GPU configurations or extreme overclocking headroom should look at higher-capacity units. Those requiring specific cable counts or connector types not listed here should verify compatibility separately.

Zero RPM Fan Mode and Topology Reduce Audible Noise

The Zero RPM fan mode stops the cooling fan entirely at low and medium loads, removing fan noise during typical desktop use. Resonant LLC topology with DC-to-DC conversion reduces coil whine, contributing to quieter operation overall. These features combine to lower acoustic output without requiring external fan controllers or software profiles. The Modern Standby compatibility further enhances low-power state transitions for a smoother user experience.

Questions about this item

What motherboard power connectors does my board need to accept the 800W ATX supply?

The unit is an ATX power supply, so your motherboard must provide a standard 24-pin ATX connector and the required CPU auxiliary connector, typically a 4+4-pin EPS plug.

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

Yes; the fan remains off at low and medium loads regardless of which GPU is installed, and the 80 PLUS Gold efficiency helps keep overall system power draw down.

How can I confirm the power supply is delivering Modern Standby wake performance after installation?

Put the PC to sleep and wake it; the system should resume in seconds rather than tens of seconds, showing the fast wake-from-sleep capability is active.
