ASUS ATS-850G power supply unit 850 W 20+4 pin ATX ATX Black

The ASUS-ATS-850G power supply delivers 850W of continuous power designed to support high-performance desktop systems. Built with a focus on efficiency and stable voltage delivery, this PSU is intended for systems running demanding CPUs and discrete graphics cards. The unit incorporates modular cabling to reduce clutter inside the case and includes multiple built-in protection mechanisms to maintain component safety under fluctuating loads.

Advantages

High power capacity combined with efficient power conversion reduces thermal losses and supports sustained peak loads. Modular cables simplify installation and improve airflow by allowing users to connect only the necessary leads. Integrated protection features such as over-voltage, under-voltage, over-current and short-circuit protection help prevent damage to connected components. The compact design and standard form factor make it compatible with many case layouts.

Suitable for

• Gaming desktops with mid to high-end graphics cards
• Workstations for content creation, video editing and 3D rendering
• Home or office systems that require reliable continuous power delivery
• PC builds where cable management and airflow are important

Key specifications

• Output power: 850 watts continuous
• Form factor: ATX-compatible power supply
• Cabling: modular cable design for selective connection
• Efficiency: high-efficiency power conversion (meets modern PSU efficiency standards)
• Protection features: over-voltage, under-voltage, over-current and short-circuit protection
• Cooling: integrated fan with thermal management for regulated temperatures

How to use

Install the PSU into a compatible ATX case following the case manufacturer’s mounting points, align screw holes and secure the unit with the supplied screws. Connect the main 24-pin motherboard connector and the required CPU 4/8-pin power connector(s) first, then attach graphics card PCIe power cables and any necessary SATA or peripheral connectors. Use only the modular cables needed for your build to maintain optimal airflow. Verify all connections are secure before powering on the system and perform an initial POST to confirm stable operation.

Recommendations

For best results, pair the power supply with components whose combined power draw remains within the PSU’s rated capacity and allow for headroom to accommodate peak loads. Ensure the case provides adequate ventilation and keep dust filters clean to maintain cooling efficiency. If using high-power multi-GPU setups or heavily overclocked components, consider monitoring system voltages and temperatures under load to confirm stable performance.
