Silent OperationThe C Series Bronze utilizes DC-DC technology to allow operation to generate less heat to reduce the fan RPM. The 135 mm PWM silent fan ensures the power supply can silently operate at high load. Capacitors, transformers, and coils have undergone treatment to reduce electromagnetically induced acoustic noise. |
Compatible and EfficientThe C Series fits any case supports ATX PSU, supporting most of the latest NVIDIA 30 series and AMD 6000 series GPUs. |
Going for the GoldThe C Series Gold PSUs are 5% more efficient than the C Series Bronze and the power conversion efficiency reaches 1.5% higher than 80plus Gold Standard at 50% load high line input voltage. |
