800 W ATX power supply for modern PCs

This 800 W ATX unit targets builders who want efficient, quiet power for mainstream systems. It carries 80 PLUS Gold certification and supports Modern Standby for rapid wake-from-sleep behaviour. The resonant LLC topology with DC-to-DC conversion delivers clean voltage regulation across the load range. It suits users who value low idle draw and stable output.

Gold efficiency, Zero RPM fan, LLC topology

At low and medium loads the fan stops completely, eliminating audible noise during everyday tasks. The 80 PLUS Gold rating ensures high efficiency, which reduces waste heat and keeps internal temperatures lower. Resonant LLC topology with DC-to-DC conversion minimises coil whine and supports deeper sleep states. Normal operation stays cool and quiet without user intervention.

Standard ATX fit with Modern Standby support

The supply uses the standard ATX form factor, so it fits typical chassis layouts without special brackets. Modern Standby compatibility allows the system to enter and exit low-power states quickly, freeing the builder from long wake delays. No proprietary connectors or non-standard dimensions are required. It leaves cable routing and airflow management to the case design.

Questions about this item

How do I install the KHACHIMO DPS-800AB-60B in a standard ATX case, and what step is often missed?

Mount the ATX unit with four screws, connect the 24-pin motherboard and CPU power cables, then enable Modern Standby in the BIOS so the fast wake-from-sleep feature actually works.

What maintenance will this 800W power supply need over its life?

The Zero RPM fan mode keeps the fan off at low loads, but dust still builds up inside; clean the intake vents yearly with compressed air to maintain the Gold-rated efficiency and cooling.

What limit appears first when the DPS-800AB-60B runs at sustained high load?

The resonant LLC topology with DC-to-DC conversion delivers clean power up to 800 W, so the first constraint is the 80 PLUS Gold thermal threshold — keep case airflow adequate to stay within it.
