Compatibility and Validation
Digital Power Control with ASUS DIGI+ VRM
Voltage regulator modules (VRMs) are essential motherboard components. A good VRM delivers CPU power based on actual needs at any given time. ASUS was first with digital power design featuring fast sensing and response, to deliver precise CPU power on demand. This accuracy reduces energy waste and improves system stability.
Enhanced DRAM Overcurrent protection
Onboard resettable fuses prevent overcurrent and short-circuit damage. This extends beyond I/O ports to DRAM to safeguard the life-span of both your system and connected devices.
5,000-hr Solid-State Capacitors
Solid-state capacitors are able to withstand temperatures of up to 105°C for as long as 5,000 hours, that is two-and-a-half (2.5x) times longer than traditional capacitors. This durability means optimal endurance to more typical PC operating temperatures, ensuring that ASUS motherboards continue working longer.
Stainless-Steel Back I/O
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 life-span that is three times (3x) longer compared to ordinary panels.
ESD Guards for Protection
Electrostatic discharge (ESD) can happen suddenly, and its damaging effects are easily underestimated. ASUS ESD guards are tested to high standards, capable of up to +/- 10kV for air discharge and +/-6kV for contact discharge. The motherboard employs an active protective circuit design to guard your system against electrostatic interference and damage, providing greater component longevity.
Additional on-circuit ESD TVS diodes to protect D-sub functionality.

Compatibility and Design
ASUS motherboard is compatible with multiple devices. The ASUS engineers fit and assess both server and consumer CPUs, most of the memory modules and graphics cards, loads of storage devices, power supplies, network devices, displays, optical drives, and peripherals. ASUS designs products from the ground up so that graphics cards, sound cards and optical drives work well with your motherboard.
Complete and Public QVL
It offers more choices for a worry-free PC-building experience. To check that a particular component or device is compatible with your motherboard, just reference the QVL for instant reassurance.
Testing for Reliability, Compatibility, and Safety
Each motherboard is subjected to extended reliability testing under heavy load conditions, from transportation to daily operations, to ensure that they it is delivered to you in a proper condition. Trials include temperature and humidity, burn-in, power on/off, power consumption, insertion, and thermal-shock testing. Every certified-compatible component is put through an up to 24-hour aging test to ensure trouble-free operation every day, no matter what you install or attach or what you do.Temperature and humidity test: Components withstand extreme conditions Thermal measurement: Cool and stable under the heaviest loads Insertion test: Guaranteed I/O reliability Power consumption test: Ensure global-standard
