ASUS PRIME X370-A AMD Ryzen AM4 DDR4 HDMI DVI VGA M.2 USB 3.1 ATX X370 Motherboard

Powered by AMD® Ryzen™ AM4 and 7th generation Athlon™ processors to maximize connectivity and speed with NVMe M.2, USB 3.1 Type A and Gigabit LAN
5X Protection III Hardware-level safeguards provide component longevity and reliability
Patent-pending SafeSlot features an injection molding process that integrates metal framing for a stronger, firmly anchored PCIe slot built for heavyweight GPUs
FanXpert 2+ with Fan RGB LED Control delivers advanced fan controls for optimized cooling
SafeSlot is the PCIe slot reinvented by ASUS and engineered to provide superior retention and shearing resistance. Manufactured in a single step using a new insert-molding process to integrate the slot with fortifying metal support for an inherently stronger design, SafeSlot is then firmly anchored to the motherboard through additional solder points.

SafeSlot Core
Fortified PCIe slot prevents damage
SafeSlot Core is the ASUS-exclusive PCIe slot. Featuring a fortified design that's anchored to the motherboard by a special hook, Safeslot Core provides 1.6x stronger retention and 1.3x greater shearing resistance than standard expansion slots.



LANGuard
Pumped-up throughput. 2.5x higher surge tolerance.
ASUS LANGuard is hardware-level networking protection that employs signal-coupling technology and premium anti-EMI surface-mounted capacitors to ensure a more reliable connection and better throughput, plus electrostatically guarded and surge-protected components for greater tolerance to static electricity and improved protection against surges.

Overvoltage Protection
World-class circuit-protecting power design
An exclusive circuit design with built-in voltage regulators to protect your chipset, connectivity ports, and audio codecs from damage caused by unexpected high-level voltages from unstable or inferior power supplies.

ESD Guards
Electrostatic discharge protection
ASUS ESD Guards prevent damage from electrostatic discharge, up to +/- 10kV for air discharge and +/- 6kV for contact discharge, arranged in an active-protective-circuit design that prolongs the life of components.
