ASUS PRIME-850G
This record covers the manufacturer-listed model PRIME-850G only. Do not treat same-family wattage variants, suffixes, regional assemblies or revisions as interchangeable.
HIGH-VOLTAGE SAFETY: Disconnect mains before external inspection. Never open or probe a PSU. Internal capacitors may retain hazardous charge after disconnection. Use qualified service or replace the complete unit.

Compatibility & safe handling
- The PRIME-850G specification names one PCI-E 16-pin 12V-2x6 lead and three 6+2-pin leads. It is not the AP-850G cable map; use only the correct model’s cable bundle and manual.
- Check motherboard ATX and CPU EPS requirements, GPU connector type and current rating, total system demand, chassis envelope, airflow, screw pattern and cable bend room; the ATX exterior alone does not prove electrical or mechanical fit.
- Use only detachable PSU cables documented for this exact model. Modular-side pinouts are not standardized, including within one manufacturer’s product family; never swap leads based on connector shape alone.
- Check the actual nameplate for mains frequency, maximum line current and regional certification. Do not operate outside its AC input rating or use a damaged, wet, modified or unidentified supply.
- Do not use unapproved adapters to create a different GPU input. Follow the graphics-card maker’s cabling and clearance requirements and this PSU’s ASUS manual.
- Never open the supply, test internal circuitry or handle internal capacitors. Replace a suspect PSU as a unit or refer it to qualified service.
Revision & documentation notes
The PRIME-850G specification names one PCI-E 16-pin 12V-2x6 lead and three 6+2-pin leads. It is not the AP-850G cable map; use only the correct model’s cable bundle and manual. Manufacturer specifications are family references; verify the full model marking, local market version and any revision label on the physical PSU. ASUS may revise product documentation; use the manual corresponding to the exact product listing rather than a similarly named wattage model.
