5X PROTECTION III For Better Reliability And Durability

VRM Technology

The VRM (Voltage Regulator Module) are considered key components of any motherboard because it is the one which controls the voltage and supplies it in a consistent and steady flow, also play an essential role in overclocking CPUs or GPUs. The DIGI + VRM provides users with improved flexibility and more control, ensuring optimized performance, stability and power.

Electricity is essential in computing, but it can also prove to be an electronic component’s worst enemy. To avoid any irreversible damage, Asus has fitted this motherboard with fuses to protect the components from possible overvoltages.

ASUS ESD Guards Technology

But sometimes electricity comes from sources other than power, and a discharge of static electricity can sometimes be enough to turn your high-tech motherboard into a simple board. Here too Asus has taken care of the issue with ASUS ESD Guards technology.


The PRIME A320M-K motherboard is also distinguished by the use of 5X solid capacitors (8000 operating hours instead of traditional capacitors. These capacitors are a further guarantee of reliability, durability and stability for a more extended period.

Finally, the connectors on the rear panel of the ASUS PRIME A320M-K motherboard are made of stainless steel which prevents the formation of rust which could cause the ports to malfunction, or even the motherboard. A significant point if you live in especially a hot and humid region.
