PRIME B350 series motherboards are engineered with industry-leading 5X Protection III, employing the finest components, excellent circuit design, and exacting standards to guarantee the quality and long-term durability of your motherboard. That means exceptional protection and stability for your build — thanks to decades of engineering experience from the world's leading motherboard brand.

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.

ASUS Prime motherboards have strengthened solder points around both the PCIe and DIMM pins.

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.
