Fonte de alimentação ASUS TUF-GAMING-850G-EVO 850W ATX 80 PLUS Gold 20+4-Pin, 1 ventoinha, Preto

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

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.

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.
