Product information

Description

The Seasonic G12 GC Series is an ATX power supply available in common wattages for PC systems. It meets the 80 PLUS Gold efficiency standard, delivering at least 87% efficiency at 20% load, 90% at 50% load, and 87% at 100% load. The unit combines this efficiency with Active Power Factor Correction, an LLC resonant converter topology, and Seasonic’s Smart and Silent Fan Control (S2FC) to reduce energy waste and maintain stable operation.

Advantages

The G12 GC Series provides high conversion efficiency that lowers electricity consumption and operating costs. Active Power Factor Correction improves power quality and reduces reactive current. The LLC resonant converter design enhances voltage regulation and overall reliability, while the Smart and Silent Fan Control balances cooling performance with low noise.

Key specifications

  • Wattage: 850 W
  • Input voltage: 100–240 V
  • Frequency: 50/60 Hz
  • Form factor: ATX
  • Efficiency rating: 80 PLUS Gold
  • Fan: 12 cm (Active)
  • Color: Black

How to use

Install the power supply into a compatible ATX PC case following the manufacturer’s installation instructions and safety guidelines. Connect the main 24-pin motherboard connector, CPU power connector(s), and required PCIe, SATA, and peripheral cables to the corresponding components. Ensure the input voltage selector (if present) matches your mains voltage and secure all connectors before powering on the system.

Recommendations

Use the Seasonic G12 GC Series in systems that require reliable, efficient power delivery such as gaming or workstation builds. Match the 850 W model to system power requirements with an appropriate margin for peak loads, and ensure good case airflow to maximize cooling and fan longevity.
