The JUSB1 (red mark) connector supports MSI’s new Super-Charger technology
which provides quicker USB charging of your smartphone or other USB-powered
devices. To enable this feature, please install the MSI Super-Charger application
on your computer. When the Super-Charger application is turned on, the JUSB1
connector will convert data channels to extra power channels to quickly charge your
connected device. Please note that when the Super-Charger application is turned on,
data transmission and synchronization over the JUSB1 connector will not function. To
enable the JUSB1 connector to function as a normal USB 3.0 connector, please turn
off the Super-Charger application. When the computer is in stand-by or hibernation
mode (S3/ S4/ S5) Super-Charger mode will automatically be enabled.
Important
• Note that the VCC and GND pins must be connected correctly to avoid possible
damage.
• To use a USB 3.0 device, you must connect the device to a USB 3.0 port through
an optional USB 3.0 compliant cable.
• Please only connect one device per USB port to ensure stable charging.
• Super-Charger Technology is only available on select MSI motherboard models.
Please refer to the MSI website to check if your motherboard has Super-Charger
technology.
• For iPad, JUSB1 (red mark) can still charge iPad in S3, S4, S5 state.
• We recommend that don’t disconnect the device when you charge it in S1 state.
