With ASUS ESD Guards your B85-PRO GAMER is actively protected against sudden electrostatic discharge (ESD), meaning the components will last much longer — and you get protection that's up to twice as resilient as industry standards!
ESD Guards include:
Keyboard and mouse connectors:
Additional on-circuit ESD TVS diodes.
USB 3/2.0 connectors:
On-circuit transient-voltage-suppression (TVS) diodes and capacitor protection for surface-mount and dual-inline packages.
Capacitor protection on both front and back audio-output circuits.
ESD TVS diode protection on the LAN circuit bolstered by an anti-surge LAN connector that increases protection against extreme events, such as lightning strikes.
