900W ATX Power Supply

The KHACHIMO 900W ATX unit delivers 900 watts of continuous power for desktop PCs. It carries 80 PLUS Gold certification and uses a resonant LLC topology with DC-to-DC conversion for stable voltage regulation. Modern Standby compatibility enables rapid wake-from-sleep transitions and improved low-load efficiency.

Builders seeking quiet operation and high efficiency

This supply suits systems where low noise and reduced energy draw matter. The Zero RPM fan mode stops the fan completely at low and medium loads. Buyers who need a different wattage rating or a non-ATX form factor should consider other options.

Standard ATX installation with silent running

Installation follows the usual ATX mounting pattern and cable routing. The resonant LLC design helps minimise coil whine during operation. Ensure the case provides adequate clearance for the ATX footprint and that all required connectors match the build.

Questions about this item

What motherboard power connectors must my board provide for this 900 W ATX unit?

Your motherboard needs a standard 24-pin ATX connector and the matching CPU power connector (usually 4-pin or 8-pin EPS) so the PSU can deliver power to the board and processor.

Will the Zero RPM fan mode still engage if I pair this supply with an older platform that lacks Modern Standby support?

Yes — Zero RPM mode is load-dependent, so the fan stays off at low and medium loads regardless of whether the motherboard supports Modern Standby.

How can I verify the 80 PLUS Gold efficiency is active after installation?

Check the PSU label for the 80 PLUS Gold logo and monitor system thermals and fan behaviour; the fan should remain off during light loads and the unit should run cooler than lower-rated supplies.
