ASUS Prime 850G 850W 80 PLUS Gold ATX Power Supply 90YE00U2-B0NA00

The ASUS Prime 850W Gold Black Edition is an 850 W fully modular power supply designed for high-performance workstations, all-round desktop PCs and gaming systems. With ATX 3.1 compliance, PCIe 5.1 compatibility and a native 16-pin 12V-2x6 graphics power connection, it is equipped for modern high-performance components. 80 PLUS Gold and Cybenetics Gold certifications, premium low-ESR components, dual-ball-bearing cooling and fully modular etched cables combine efficient power delivery with practical system integration.

Key Features

• 850 W total output provides substantial power capacity for compatible gaming, workstation and general-purpose desktop PCs.
• ATX 3.1 compliance supports modern power-delivery requirements and demanding transient loads.
• PCIe 5.1 compatible with a native 16-pin 12V-2x6 cable capable of delivering up to 600 W to a compatible graphics card.
• 80 PLUS Gold and Cybenetics Gold certifications provide efficient power conversion.
• Fully modular cabling allows unused cables to be removed for cleaner cable management and improved airflow.
• Premium etched cables use tin-plated oxygen-free copper conductors for high conductivity and flexibility.
• 135 mm dual-ball-bearing fan provides durable active cooling.
• Upgraded PCIe connectors use superior copper pins for efficient high-current power delivery.
• Multiple electrical protection mechanisms help protect the PSU and connected system hardware.
• Backed by an 8-year ASUS warranty.

850 W Power Delivery

The Prime 850W Gold provides 850 W of total output, including up to 846 W on the +12 V rail. This provides the power capacity required by compatible high-performance processors, graphics cards, storage devices and other desktop components.

ATX 3.1 and PCIe 5.1 Compatible

Compliance with the ATX 3.1 standard prepares the PSU for the transient power demands of modern PC hardware. ASUS specifies support for total power excursions of up to twice the PSU's rated power and graphics card power excursions of up to three times rated GPU power, helping maintain system stability during rapidly changing workloads.

Native 16-Pin Graphics Power

A bundled 16-pin 12V-2x6 PCIe cable provides direct connectivity for compatible PCIe 5.1 graphics cards and can deliver up to 600 W. Three conventional 6+2-pin PCIe connectors are also provided for broader graphics hardware compatibility.

80 PLUS and Cybenetics Gold

The power supply is both 80 PLUS Gold and Cybenetics Gold certified. ASUS uses low-ESR capacitors and other premium components to achieve efficient operation, with the manufacturer specifying efficiency of up to 92%. Higher efficiency helps reduce wasted energy, heat generation and cooling requirements.

Premium Etched Modular Cables

The fully modular design allows builders to install only the cables required by the system. ASUS's premium etched cables use tin-plated oxygen-free copper conductors and flexible cable jackets, helping simplify routing while providing low electrical resistance and efficient power transmission.

Durable Dual-Ball-Bearing Cooling

A 135 mm cooling fan uses a dual-ball-bearing mechanism designed for long-term durability. ASUS states that this bearing configuration can last up to twice as long as a conventional sleeve-bearing design.

Superior Copper PCIe Pins

Upgraded PCIe power connectors feature high-conductivity copper pins designed to improve thermal performance and power delivery. Under ASUS testing conditions, the design provides up to a 29% reduction in connector temperature compared with conventional connector designs.

Comprehensive Electrical Protection

The Prime 850W Gold incorporates over-current, over-temperature, over-voltage, over-power, short-circuit and under-voltage protection mechanisms to support safe and stable operation of the power supply and connected PC hardware.
