5X Protection
ASUS 5X Protection

All-round protection provides the best quality, reliability, and durability
ASUS motherboards guard your PC with 5X Protection. We use quality components like DIGI+ VRM digital power design for precise CPU power on demand, ESD units tested to strict standards that eliminate electrostatic interference, and resettable fuses around DRAM slots to prevent overcurrent and short-circuit damage. We also use corrosion-resistant back I/O shields, all examples of ASUS providing the best possible reliability and durability.


Precise power control and long-lasting stability
Voltage regulator modules (VRMs) are among the most essential motherboard components. A good VRM intelligently delivers CPU power based on actual needs at any given time. ASUS was first with digital power design featuring faster sensing and response to deliver precise CPU power on demand. This great accuracy reduces energy waste and of course improves system stability thanks to more consistent delivery.

Micro-ATX B85

Enhanced DRAM Overcurrent Protection

Short-circuit damage prevention
Onboard resettable fuses prevent overcurrent and short-circuit damage. This extends beyond I/O ports to DRAM to safeguard system and device lifespan.

Micro-ATX B85Micro-ATX B85

ESD Guards

Strong ESD protection for extended component lifespan
Electrostatic discharges (ESD) can happen suddenly, and their damaging effects are often underestimated. ASUS ESD Guards offer an active protective circuit design that ensures electrostatic discharges are properly grounded, providing greater component longevity.

Micro-ATX B85Micro-ATX B85

High-Quality 5K-Hour Solid State Capacitors

2.5X longer lifespan with excellent durability
ASUS high-quality solid state capacitors assure a 5,000-hour lifespan, equivalent to 2.5 times longer than traditional capacitors. All capacitors pass testing under temperatures as high as 105 degrees centigrade and meet Japanese industrial standards to provide excellent durability and enhanced thermal capacity.

Micro-ATX B85Micro-ATX B85

Stainless Steel Back I/O

3X more durable corrosion-resistant coating
ASUS motherboard back I/O panels are made from strong and corrosion-resistant stainless steel, which is bonded with a thin layer of chromium oxide to enhance anti-corrosive properties. Passing 72-hour spray salt endurance tests, ASUS stainless steel back I/O panels have a usage life three times longer compared to ordinary panels.
