Prime 200 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 ensuring 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. 





DIGI+ VRM

Precision control for stable power!

ASUS-exclusive DIGI+ VRM intelligently delivers power to the processor based on real-time demands, reducing energy waste and improving system stability.

Stainless-Steel Back I/O

3X corrosion-resistance for greater durability

Corrosion-resistant stainless steel back I/O panels bonded with chromium oxide have a lifespan that's three times longer than ordinary panels.


ESD Guards

Electrostatic discharge protection

ASUS ESD Guards prevent damage from electrostatic discharge, up to +/- 10kV for air discharge and +/-15kV for contact discharge, arranged in an active-protective-circuit design that prolongs the life of components.

Against moisture and corrosion

This innovative moisture-resistant coating provides motherboard protection, and combats the higher levels of humidity that build up in densely-populated environments, such as factories, libraries, data centers and internet cafes. It even minimizes internal corrosion by preventing the adhesion and migration of moisture — prolonging the life of your motherboard. 


24/7 Reliability Test

Optimized for twenty-four seven operations, the motherboard is tested under temperature up to 45°C and humidity up to 80% to ensure it can handle diverse temperature and humidity range of different location.
