800W ATX Power Supply

This KHACHIMO unit is an 800-watt ATX power supply certified to 80 PLUS Gold efficiency. It delivers stable power for desktop PCs and workstations using resonant LLC topology with DC-to-DC conversion for clean output. Modern Standby compatibility enables fast wake-from-sleep times and improved low-load efficiency. A zero-RPM fan mode stops the fan at low and medium loads for near-silent operation.

System builders who need efficient, quiet power

Suitable for builds that benefit from Gold-rated efficiency and silent running at typical workloads. The Modern Standby support suits systems that use deep sleep states and require rapid resume. Builds requiring higher wattage than 800 watts or a different form factor should consider other options. Units without ATX connectors are not a fit for this power supply.

800-watt capacity with Gold headroom

The 800-watt rating comfortably handles mid-range to high-end components including modern CPUs and graphics cards under full load. Gold certification reduces waste heat and keeps fan speeds lower across the load range. At sustained loads approaching the maximum rating the fan will engage and headroom diminishes. Peak demands above 800 watts exceed the design limit of this unit.

Questions about this item

What motherboard power connector does the DPS-800AB-2A need?

The unit follows the ATX form factor, so it uses a standard 24-pin main connector plus the required CPU and PCIe cables for your motherboard and graphics card.

Can I keep using my older ATX motherboard with this 800 W unit?

Yes, the ATX design fits any standard ATX case and motherboard, delivering up to 800 W through the usual 24-pin, CPU and PCIe connectors.

How can I confirm the fan is behaving correctly after installation?

Under light loads the fan should stay completely still thanks to Zero RPM mode; it will spin up only when the load or temperature rises enough to require active cooling.
