SAPPHIRE NITRO+ & PULSE AMD Radeon RX 7800 Series are designed with digital power which provides accurate power control and excellent power efficiency. The Ultra High Performance Conductive Polymer Aluminum Capacitor has a small PCB foot print but high volumetric capacitance that makes 14-phase power possible on the RX 7800 series graphics card. The capacitor offers stable capacitance at a high frequency and temperature with very low signal noise, ensuring the stability and reliability of the product. The GPU is mounted on to the high-density 14 layer 2oz Copper and high TG PCB to match the rapid speed, high current and increased power requirement of the GPU and memory to guarantee high stability of the PCB during operation. The composite heatpipes are fine-tuned for each individual cooling design with optimal heat flow, efficiently and evenly spreading out the heat to the entire cooling module. In order to protect your card, the SAPPHIRE cards have fuse protection built into the circuit of the external PCI-E power connector to keep the components safe.
