Key Features

850W High-Performance Power Delivery

The ASUS TUF Gaming 850W Gold provides 850W total output, with the +12V rail delivering up to 70.8A.

This power capacity is designed for demanding gaming systems, high-performance PCs and graphics cards requiring substantial and stable power delivery.

80 PLUS Gold Certification

The PSU features 80 PLUS Gold certification, using Japanese capacitors and premium components to support efficient and reliable power delivery.

The efficient design helps reduce power losses and heat generation during operation.

ATX 3.1 Compatible

The ASUS TUF Gaming 850W Gold complies with the ATX 3.1 standard, providing support for modern PC platforms and next-generation graphics cards.

PCIe 5.1 Ready

The power supply includes a dedicated PCIe Gen 5.1 16-pin cable, providing modern GPU power connectivity for compatible graphics cards.

It also includes a PCIe 16-pin to 8-pin + 8-pin cable and a PCIe 1-to-1 cable for additional graphics card power configurations.

Military-Grade Components

The capacitors and chokes undergo demanding tests to achieve military-grade certification, supporting durability and reliable long-term operation.

The PSU is also subjected to extensive environmental and durability testing.

Dual Ball Fan Bearings

The cooling fan uses dual ball bearings, which ASUS states can last up to twice as long as sleeve-bearing designs.

This helps provide dependable cooling performance over the PSU's service life.

Protective PCB Coating

A protective PCB coating helps protect the internal electronics against moisture, dust and extreme temperatures.

This provides an additional layer of protection for the PSU's internal circuitry.

Axial-Tech Fan Design

The Axial-tech fan design uses a smaller fan hub that allows longer blades, while a barrier ring increases downward air pressure.

This design helps improve airflow through the power supply while supporting efficient cooling.

Fully Modular Etched Cables

The ASUS TUF Gaming 850W Gold uses fully modular etched cables, allowing users to connect only the cables required by their system.

The flexible cables also make cable routing and internal PC management easier.

PCIe Gen 5.1 Ready

The ASUS TUF Gaming 850W Gold includes a PCIe Gen 5.1 16-pin cable measuring 675mm.

It also includes:

• PCIe 16-pin to 8-pin + 8-pin cable — 675mm
• PCIe 1-to-1 cable — 675mm

This provides flexible connectivity for compatible modern graphics card configurations.

0dB Fan Operation

The ASUS TUF Gaming 850W Gold operates in 0dB mode by default.

The fan remains off during lower-load conditions and spins up when the system reaches a certain load level, helping provide quieter operation when full cooling capacity is not required.

High-Performance Copper Pins

Upgraded PCIe connectors feature high-performance copper pins designed to provide improved thermal conductivity and efficient power delivery.

ASUS states that this design can achieve a 29% reduction in connector temperatures, up to 12.28°C, under its specified testing conditions.

This helps promote stable operation for demanding graphics cards.

Premium Durability Testing

The ASUS TUF Gaming 850W Gold undergoes demanding testing designed to verify reliability and durability.

Testing includes:

• MTBF testing
• 75cm drop testing
• Vibration testing
• Extreme temperature testing
• Corrosion-resistance testing

The PSU is tested through temperature changes from -40°C to 85°C for 27 cycles while maintaining operation.

ASUS also specifies corrosion-resistance testing involving up to 95% humidity with salt fog for up to 240 hours.

Etched Cable Design

The fully modular etched cables are made from a pliable material designed to make installation and cable management easier.

The cable construction supports flexible routing while helping maintain a neat internal PC build.

Comprehensive Protection Features

The PSU incorporates multiple protection mechanisms:

• OPP — Over-Power Protection
• OVP — Over-Voltage Protection
• UVP — Under-Voltage Protection
