Compatibility: supports PCIe slots 1x, 4x, 8x, and 16x for flexible integration with multiple addon cards. Device coverage: suitable for sound cards, networking cards, data acquisition cards, and other devices that use PCIe interfaces. Contact construction: gold plated contact points reduce resistance and help resist temperature changes, contributing to reliable performance. Signal integrity: uses gold sinking technology to strengthen the connection and maintain stable signal transmission. Build and durability: designed to provide solid performance through durable construction and quality connectors. Practical use scenarios: Upgrading a desktop or workstation to add or a sound card or network card via PCIe expansion. Building a small lab workstation for data acquisition or measurement tasks that require reliable PCIe connections. Quick testing and development setups where multiple PCIe devices need stable, temporary expansion. Key attributes at a glance: function expansion through PCIe compatibility, broad device support, gold plated contacts for durability and heat resistance, gold sinking technology for stronger connections and stable signals.
