GAMEMAX GX-850 Pro 850W Modular Power Supply - ATX3.1 & PCIe 5.0 Ready

The GAMEMAX GX PRO 850G delivers 850W of reliable power with 80 Plus Gold certification, achieving over 90% efficiency under typical loads. Built with APFC+LLC+DC-DC design, this fully modular power supply minimizes power waste while maintaining quiet operation.

ATX3.1 & PCIe 5.1 Compatibility

Equipped with a native 12V-2x6 connector, the GX-850 Pro supports next-generation GPUs including RTX 40 and 50 series graphics cards. The high-efficiency, low-loss transformer handles 2x power excursions seamlessly, ensuring stable performance during demanding workloads.

Premium Components & Durability

Japanese 105°C capacitors and solid capacitors provide long-term stability and performance. The robust construction includes dual-stage EMI filtering with NTC thermistor and relay protection against spikes, surges, noise, and interference. Gold-plated cables ensure durable, high-conductivity connections throughout the system.

Advanced Cooling & Quiet Operation

The 135mm FDB (Fluid Dynamic Bearing) fan features intelligent temperature control technology that automatically adjusts speed based on load. At low loads, the fan reduces speed to minimize noise levels below 25dBa, while maintaining optimal heat dissipation during intensive tasks.

Comprehensive Protection Features

Multiple protection technologies safeguard your components: OPP (Over Power Protection), OVP (Over Voltage Protection), UVP (Under Voltage Protection), OCP (Over Current Protection), SCP (Short Circuit Protection), OTP (Over Temperature Protection), NLP, SIP, OLP, and NLO. These systems ensure hardware stability while preventing damage and interference.

Fully Modular Design

The wireless technology design uses pin and high-density copper pillars for PCB connections, reducing internal wiring and enhancing reliability. This improves space utilization, increases cooling airflow, and extends component lifespan. Embossed flat cables provide neat cable management with ample connectors supporting dual CPUs or three 8-pin connectors for flagship GPUs, plus 6 SATA connections.
