## Long description

The ASUS TUF-GAMING-850G-EVO is an 850 W ATX power supply unit with 80 PLUS Gold efficiency designed for desktop PCs. It delivers stable power through a 20+4 pin ATX motherboard connector and includes cables for CPU, PCIe, SATA and Molex devices. The unit supports AC input from 100–240 V, features active power factor correction and a single cooling fan, and uses components and protections intended to provide durable operation for gaming and workstation rigs.
Advantages
The TUF Gaming Gold EVO series combines military-grade capacitors and premium components to provide high reliability and consistent voltage delivery under load. An advanced cooling solution with dual-ball bearing technology increases fan lifespan compared with sleeve-bearing designs while a protective PCB coating helps resist moisture, dust and temperature stress. 80 PLUS Gold efficiency reduces wasted energy and heat, improving system efficiency and long-term operating cost. ATX 3.1 compatibility and included PCIe cabling ensure support for modern high-power graphics cards.
Suitable for
Gaming desktops requiring 850 W power and high efficiency
High-performance workstations with discrete graphics cards
System builders seeking durable components and long-term reliability
Upgrades to ATX 3.1-compatible systems or PCIe Gen 5.1 GPUs
Key specifications
Total output: 850 W
Efficiency rating: 80 PLUS Gold
Input voltage: AC 100–240 V
Motherboard connector: 20+4 pin ATX
Cooling: single fan with dual-ball bearing design
Protection: coated PCB for moisture, dust and temperature resistance
Cabling: includes CPU, PCIe, SATA and Molex cables; motherboard cable length ~50 cm; SATA cable lengths 400 mm and 120 mm
How to use
Install the PSU into a compatible ATX case aligning the mounting holes and secure it with the supplied screws. Connect the 20+4 pin ATX cable to the motherboard and attach the CPU power connector, PCIe connectors for the graphics card, and SATA/Molex connectors for drives and peripherals as required. Ensure the AC mains voltage matches the PSU input (100–240 V) and use a properly grounded outlet. Allow unobstructed airflow around the intake and exhaust areas of the case to maintain cooling performance.
Usage recommendations
For reliable operation, use the ASUS TUF-GAMING-850G-EVO with systems whose combined component power draw stays well below the 850 W rating to allow headroom for peak loads. Keep intake paths clear of dust and verify cable routing for adequate airflow. When installing high-power graphics cards, use the supplied PCIe cable compatible with ATX 3.1/PCIe Gen 5.1 where applicable.
