Dependable Reliability

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.
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. 
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. 

Efficient Management
