850 W ATX power supply

The KHACHIMO PAC-850WL-LE is an 850 W ATX power supply built for desktop PCs that demand efficient and quiet power delivery. It carries 80 PLUS Gold certification and uses a resonant LLC topology with DC-to-DC conversion to provide clean, consistent output while reducing coil whine.

Suited for Modern Standby systems needing low-load

This unit suits builders who want fast wake-from-sleep times and near-silent operation at low and medium loads thanks to its Zero RPM fan mode. It is not for users who require a fully modular cable set or a higher wattage rating for extreme multi-GPU configurations.

Verify ATX fit and cable reach before ordering

Check that your case accepts a standard ATX power supply and that the fixed cables reach your motherboard, CPU and graphics connectors. Ensure the total system power draw stays within the 850 W rating and confirm the unit provides the PCIe connectors your graphics card requires.

Questions about this item

What type of motherboard power connector does the PAC-850WL-LE require?

The PAC-850WL-LE uses the standard ATX form factor, so it connects to any motherboard with a 24-pin ATX power socket and matching CPU power headers.

Will the 850W unit work with an older graphics card that only needs a 6-pin PCIe connector?

Yes, the power supply includes modular cables with 6+2 pin PCIe connectors that are backward-compatible with 6-pin only graphics cards.

How can I confirm the Zero RPM Fan Mode is active after building the system?

Under light workloads the fan will stop spinning completely; you can verify this visually or by listening for the absence of fan noise while the system is idle.
