Product information

Description

The Seasonic G12 GM Series is an ATX power supply available in wattages commonly used in 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 design includes Active Power Factor Correction and an LLC resonant converter to reduce energy loss and improve stability. The unit also incorporates Seasonic's Smart and Silent Fan Control (S2FC) for optimized cooling and low noise.

Advantages

The G12 GM Series offers high energy efficiency that helps lower electricity consumption and operating costs while maintaining reliable power delivery. The LLC resonant converter enhances voltage stability and performance. S2FC provides intelligent fan management to balance thermal control and acoustic quietness, making the PSU suitable for typical desktop builds.

Key specifications

  • Form factor: ATX
  • 80 PLUS certification: Gold (≥87% at 20%, 90% at 50%, 87% at 100%)
  • Power factor correction: Active PFC
  • Converter topology: LLC resonant converter
  • Cooling: Smart and Silent Fan Control (S2FC)

How to use

Install the power supply in a compatible ATX case following the motherboard and case manufacturer instructions. Connect the appropriate cables to the motherboard, CPU, GPU and drives, ensuring secure connections and correct pin alignment. Verify voltage selector (if present) and use a compatible power cord. Allow adequate airflow around the PSU and avoid obstructing the fan to maintain optimal cooling and performance.

Recommendations

For best results, choose a G12 GM wattage that provides sufficient headroom above your system’s typical power draw. Periodically check and clean dust from ventilation areas to preserve efficiency and quiet operation.
