GAMEMAX GX-850 Pro 850W Modular Power Supply

The GAMEMAX GX-850 Pro delivers 850W of reliable power for high-end gaming systems and workstations. This fully modular ATX 3.0 power supply combines 80 Plus Gold efficiency with next-generation PCIe 5.0 support, making it ready for the latest RTX 40-series graphics cards and demanding PC builds.

ATX 3.0 and PCIe 5.0 Compatibility

Built to ATX 3.0 specifications, the GX-850 Pro includes a native 12VHPWR 16-pin connector capable of delivering up to 600W to PCIe 5.0 graphics cards. This eliminates adapter cables and ensures stable power delivery to RTX 3090 Ti, RTX 4080, RTX 4090, and future high-performance GPUs.

80 Plus Gold Certified Efficiency

With over 90% energy efficiency at typical loads, the 80 Plus Gold certification reduces heat generation and electricity costs. The high efficiency rating ensures more power reaches your components while less energy is wasted as heat, contributing to a cooler and quieter system.

Advanced Cooling with 135mm Axial-Tech Fan

The customized 135mm Fluid Dynamic Bearing fan uses Axial-Tech design for optimized airflow and minimal noise. The spiral blade pattern increases air pressure while maintaining acoustics below 25dBa. Intelligent temperature control activates the fan only when power consumption exceeds 20%, enabling silent operation during light loads and extending fan lifespan.

Premium Japanese Components

Internal construction features Japanese 105°C-rated capacitors for maximum reliability and longevity. These high-grade components ensure stable voltage delivery and contribute to the 100,000-hour MTBF rating, providing years of dependable service.

Fully Modular Cable Design

The modular cable system allows you to connect only the cables your build requires. Low-profile flat cables improve airflow, reduce cable clutter, and simplify installation. The included modular cable bag keeps unused cables organized.

Comprehensive Protection Suite

Six protection circuits safeguard your components: Over Voltage Protection (OVP), Over Current Protection (OCP), Over Power Protection (OPP), Short Circuit Protection (SCP), Under Voltage Protection (UVP), and Over Temperature Protection (OTP). These protections monitor power delivery continuously to prevent damage from electrical faults.
