Cooler Master Fully Modular Elite Gold 850W Power Supply | ATX 3.1 | 80 Plus | MPX-8505-AFAG-BUS

The Cooler Master Elite Gold 850W is a next-gen power supply built for high-performance gaming PCs, workstations, and commercial builds. With ATX 3.1 and PCIe Gen 5.1 support, it handles peak power demands up to 200% of rated capacity, making it ideal for RTX 50 series GPUs and future hardware.

80 PLUS Gold certified for ≥90% efficiency, this fully modular PSU cuts heat and power waste while keeping your system cool and quiet. The compact 140 mm depth fits easily into tight cases, and flat embossed cables route cleanly for a professional build. Its rifle bearing fan runs whisper-quiet even under sustained loads up to 40°C.

Complete protection circuitry safeguards against surges, short circuits, and thermal stress. Backed by a 10-year warranty and rated for over 100,000 hours of reliable operation, the Elite Gold 850 delivers the stability and longevity serious builders expect.

Features
Native ATX 3.1 & PCIe Gen 5.1 Architecture: Engineered with advanced power excursion handling up to 200% of rated capacity, delivering stable, tightly regulated voltage to high-demand graphics processors.
80 PLUS Gold Certified Efficiency: Reaches ≥90% efficiency under standard loads to minimize electrical waste, reduce operating heat, and lower total power draw.
Space-Saving 140 mm Form Factor: Features a shortened chassis profile that fits easily into compact mid-tower and small-footprint cases, leaving more space for airflow and cable routing.
Fully Modular Embossed Flat Cables: Allows builders to connect only the necessary leads for an uncluttered build, featuring embossed flat cables that provide superior grip and a clean aesthetic.
Acoustically Optimized Rifle Bearing Fan: Employs a 120 mm rifle bearing cooling fan designed for quiet operation and long-term mechanical reliability.
High-Temperature Operation (Up to 40°C): Operates reliably in ambient environments up to 40°C, sustaining peak output during heavy rendering, prolonged simulation, or intense gaming sessions.
Comprehensive Circuit Protection Suite: Safeguards mission-critical components against electrical faults with UVP, OVP, OPP, OTP, and SCP protections.
10-Year Manufacturer Warranty: Provides long-term operational assurance and a low total cost of ownership across the PSU's complete lifecycle.
