Product Highlights
Exterior
The Silent Pro Gold 800W power supply unit features a sleek black chassis with gold accents and prominent "Silent Pro Gold 800W" branding. The design includes a golden fan cover, a 120/135 mm fan for cooling, a logo decor sticker, and a honeycomb vent pattern for airflow. It also incorporates a modularized cable design with flat modular connectors, a quality spray finish, and a cable protector.
Fan Control and Noise Level
This section presents a graph illustrating the relationship between system loading (X-axis, 0-100%) and fan performance. The left Y-axis shows fan noise in decibels (dBA), and the right Y-axis shows fan speed in revolutions per minute (RPM). The blue line represents fan noise, and the orange line represents fan speed. As the system load increases, both fan speed and noise level gradually rise.
High Efficiency
This graph demonstrates the power supply's efficiency across different loading percentages (X-axis) under two input voltage conditions: 230V/50Hz (blue line) and 115V/60Hz (orange line). The Y-axis indicates efficiency in percentage. The Silent Pro Gold 800W consistently achieves high efficiency, exceeding 88% and reaching over 92% at higher loads, particularly under 230V/50Hz operation, confirming its 80 PLUS Gold certification.
