ASUS Pro B550M-C/CSM / Motherboard / micro ATX / Socket AM4 / AMD B550 Chipset / USB-C Gen2, USB 3.2 Gen 1, USB 3.2 Gen 2 / Gigabit LAN / onboard graphics (CPU required) / HD Audio (8-channel) | 90MB15Q0-M0EAYC
Product Features
- ASUS Self-recovering BIOS
ASUS-exclusive BIOS protection technology automatically recovers the system BIOS with a verified backup in the event of an update failure, preventing the need to replace or reinstall hardware. - ASUS Secure Boot
ASUS business motherboard is set to check the firmware and signature of each piece of boot software. - Trusted Platform Module (TPM)
Hardware-based security offers better data protection, enhances network security, protects digital identities and ensures platform integrity. - ASUS Trouble Shooting Solution
ASUS Debug header is a 10-1 pin low pin count (LPC) header for connecting to debug cards for faster, more efficient motherboard troubleshooting. When connected to an ASUS Debug Card, administrators can view error and debugging codes on the integrated LCD display, and get better idea of initialization and recovery processes. ASUS business motherboards provide a complete troubleshooting solution, making mass production faster and more cost effective. - Fixed-position connectors
Connector positions on ASUS business motherboards remain consistent across product generations, protecting training, manufacturing and investments in supporting hardware.
