  • On/Off Charge Technology
    GIGABYTE On/Off Charge technology allows you to charge your iPhone, iPad and iPod Touch regardless of whether your PC is on, in standby mode or even off. A derivative of GIGABYTE's highly acclaimed 3x USB Power feature, On/Off Charge enables devices to draw more current from GIGABYTE motherboard USB ports than standard USB ports allow, so that charging from your PC can be as fast as with a charger...more
    *Due to certain mobile phone limitations, users may need to connect the mobile phone to their PC before the PC enters S4/S5 mode to enable a quick charge from non On/Off Charge USB ports. Charging results may vary by model.
    *Whether to support 3X USB power design, it may vary by models.
