ASUS specifies a 52% wider temperature tolerance and up to a 2.5X longer lifespan compared with standard capacitors.

135mm Dual-Ball-Bearing Fan

The PSU uses a 135mm cooling fan with dual-ball bearings.

ASUS states that the dual-ball-bearing design can last up to twice as long as a sleeve-bearing design, supporting long-term cooling reliability.

Protective PCB Coating

A protective conformal coating covers the PCB to help protect the internal electronics against moisture, dust and debris.

This helps reduce the risk of short circuits caused by environmental contaminants.

Superior Copper Pins

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

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

This helps support stable operation when powering demanding graphics cards.

Premium Embossed Cables

The TUF Gaming 850W Gold EVO uses premium embossed cables made from a pliable material designed for easier installation and cable management.

The cable construction consists of:

• Solid-core copper wire
• Tin-plated layer
• Embossed cable jacket

The cables are designed to provide:

• Ultra-high conductivity
• Long lifespan
• Long-term stability
• High ductility and bendability
• Low resistance
• Low heat generation

ASUS states that these cables operate at temperatures 50°C below the safety limit when routed for cable management.

The cables also meet the UL1581 flame test and UL758 certification requirements.
