GAMEMAX GP 650B White 80+ Bronze Ultra-Stable Power Supply with Dual DC-DC Control, Smart Fan, and Premium Heat Dissipation.
• Dual Control DC-DC Circuit: Features 180-degree phase-shifted 3.3V/5V outputs, minimizing impact on +12V input and reducing ripple noise for enhanced stability and ±2% voltage accuracy.
• Premium Taiwan Capacitors: Utilizes high-quality TEAPO capacitors for reliable full-load performance and stable power delivery.
• Smart Temperature Control Fan (12/14CM): Automatically adjusts fan speed based on load, balancing energy efficiency and low-noise operation.
• Double-Sided PCB with Top-Side SMD Layout: Single-sided component design (no bottom components) improves stability and manufacturing precision.
• Enhanced Heat Dissipation: Aluminum extrusion and optimized crystal heat dissipation architecture ensure efficient cooling for sustained performance.
