DIGI+ VRM

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.

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
* The location of fuses vary with models.

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.

High-Quality 5K-Hour Solid-State Capacitors

2.5X longer lifespan with excellent durability

ASUS high-quality solid-state capacitors offer great durability, excellent thermal resilience and an incredible lifespan. Our capacitors have been tested to withstand temperatures as high as 105 degrees centigrade and will provide over 50 years of continuous use at 65 degrees centigrade – that’s 2.5 times longer than traditional capacitors.

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.
Protective coating leads to extra durability
Non-stainless steel easily oxidizes and rusts
