800 W ATX power supply

The KHACHIMO M6 delivers 800 W of continuous power in a standard ATX form factor. It is built for system builders who need reliable energy delivery for mid-to-high-range desktop components. The unit carries 80 PLUS Gold certification for efficient operation across typical loads. Modern Standby compatibility ensures rapid wake-from-sleep responsiveness.

Resonant LLC topology with DC-to-DC conversion

This topology supplies clean, consistent voltage to the motherboard, graphics cards and storage drives while reducing coil whine. DC-to-DC conversion on the minor rails improves cross-load stability and supports deeper sleep states. The design fits any ATX chassis without requiring proprietary cabling or mounting brackets. Zero RPM fan mode keeps the system near-silent at low and medium loads.

Modern Standby and zero-fan accessories

Modern Standby support enables extremely fast wake times and better low-load efficiency for compatible platforms. The zero RPM fan mode eliminates acoustic noise during idle and light workloads. No additional software suite or proprietary connectors are bundled with the unit. Builders who need modular cables or higher wattage headroom should verify their requirements before purchase.

Questions about this item

How much continuous power can the 800W unit deliver before its protections trigger?

The power supply is rated for 800W continuous output, so its over-power protection will engage only when the load exceeds that level.

Does the Zero RPM fan mode stay off once the PSU runs at full load for hours?

At low and medium loads the fan stops completely; under sustained high load the fan will spin to keep temperatures in check.

Which motherboard power connector must my board provide for this ATX unit to start?

It requires a standard 24-pin ATX main connector plus the appropriate 4+4-pin or 8-pin CPU power cable from the PSU.
