SUS Prime 850W 80 PAlus Gold ATX 3.1 & PCIe 5.1 Fully Modular Power Supply Black Edition – PRIME-850G

Stellar Performance for High-Performance Rigs

The ASUS Prime 850W Gold Black Edition Power Supply Unit stands as an uncompromising powerhouse designed to bring efficient, durable, and rock-solid power delivery to high-performance workstations, all-round personal computers, and elite gaming rigs. Engineered to meet the demanding needs of modern multi-core processors and next-generation graphics cards, this power supply combines premium Japanese capacitors, advanced thermal management, and robust circuit protection mechanisms to ensure your entire system operates at peak stability under any workload.

Adherence to Latest ATX 3.1 and PCIe 5.1 Standards

Designed from the ground up to accommodate modern hardware evolutions, the Prime Gold series fully complies with stringent ATX 3.1 guidelines and supports advanced PCIe 5.1 graphics cards. This cutting-edge architecture ensures that your system can smoothly handle total power excursions up to twice the rated power and instantaneous GPU power excursions up to three times the rated power. Bundled with a dedicated 16-pin PCIe cable capable of channeling up to 600 watts of continuous power directly to high-end graphics cards such as the GeForce RTX series, it eliminates bottlenecks and guarantees seamless compatibility with future-proof hardware layouts.

80 PLUS and Cybenetics Gold Certified Efficiency

Energy efficiency and electrical stability are cornerstones of the ASUS Prime series. Featuring low-ESR capacitors and high-grade internal components, the unit achieves official 80 PLUS Gold and Cybenetics Gold certifications. This translates to an operating efficiency of up to 92%, which directly minimizes wasted electrical energy, generates less internal heat, lowers overall fan acoustic noise, and enhances long-term reliability. Your system runs cooler, quieter, and more efficiently even during marathon gaming or heavy professional rendering sessions.

Superior Cooling with Dual-Ball Fan Bearings

Exemplary thermal management is driven by a high-performance 135mm cooling fan mounted on a dual-ball bearing setup. Unlike conventional sleeve bearing designs that degrade quickly under high thermal stress, dual-ball bearings offer an extended operational lifespan that lasts up to twice as long. This robust cooling architecture efficiently evacuates heat from internal components while maintaining a balanced acoustic profile, ensuring sustained peak performance and structural longevity for years to come.

Flexible Pliable Etched Cables for Clean Cable Management

Achieving a clean, professional interior build is effortless thanks to the fully modular etched cables included with the unit. Fabricated from a pliable premium material, these cables bend easily during installation and route smoothly through tight chassis spaces, operating well below safety temperature thresholds. Composed of tin-plated oxygen-free copper wire, they deliver ultra-high conductivity, minimal electrical resistance, reduced heat generation, and long-term durability. Certified to meet rigorous UL1581 flame tests and UL758 standards, they ensure a safe and polished DIY building experience.

Advanced Comprehensive Protection Mechanisms

Safety and hardware preservation are paramount when dealing with high-wattage components. The ASUS Prime 850W Gold PSU is equipped with an extensive suite of industrial-grade protection mechanisms, including Over-Current Protection (OCP), Over-Power Protection (OPP), Over-Temperature Protection (OTP), Over-Voltage Protection (OVP), Under-Voltage Protection (UVP), and Short-Circuit Protection (SCP). These safeguards constantly monitor voltage lines and electrical currents to protect your investment, giving you absolute peace of mind during intensive computing tasks.
