## Long description

The EFFITEK EG-850 is an 850W ATX 3.1 power supply with Gold efficiency rating and PCIe 5.1 support. Its modular cable design reduces clutter inside desktop systems while providing the wattage and connector compatibility required by modern gaming PCs and professional workstations. The unit is engineered to deliver stable voltages under varying loads and to integrate with contemporary motherboards and high-power graphics cards that use the latest power delivery standards.
Advantages
The EFFITEK EG-850 combines an ATX 3.1 form factor with an 80 Plus Gold-level efficiency, which helps lower energy losses and operating temperatures compared with lower-efficiency models. Native support for PCIe 5.1 connectors accommodates current and next-generation graphics cards that need increased power headroom. A fully modular cable system simplifies installation, improves airflow inside the case, and makes future upgrades easier by letting you attach only the cables you need.
Suitable for
 High-performance gaming PCs with modern graphics cards
 Content creation workstations for video editing and 3D rendering
 Systems requiring stable 12V rails for overclocked CPUs and GPUs
 Custom builds where cable management and airflow are priorities
Key specifications
 Continuous output power: 850 watts
 Form factor: ATX 3.1 compatible
 Efficiency certification: 80 Plus Gold
 PCIe connector support: PCIe 5.1 compatible power connectors
 Cable design: fully modular cables for selective connection
 Cooling: integrated fan with thermal management (automatic control)
 Protection features: built-in over-voltage, under-voltage, over-current, and short-circuit protections
How to use
Install the EFFITEK EG-850 in a compatible ATX case, aligning the mounting holes and securing the unit with the supplied screws. Connect the necessary modular cables to the power supply before routing them to components: motherboard 24-pin, CPU 4+4 pin as required, and PCIe 6+2/12V connectors for graphics cards. Ensure all connectors are fully seated and that cable routing does not obstruct case fans or airflow paths. Verify BIOS power settings and boot the system to confirm stable operation and correct fan behavior.
Usage recommendations
For reliable long-term performance, use the EG-850 at up to 80–90% of its rated capacity for sustained heavy loads, keep intake/exhaust airflow unobstructed, and periodically check cable seating and ventilation. When pairing with high-power GPUs, confirm connector compatibility and use the recommended combination of PCIe power cables to distribute load across rails.
