⚠
Important
If you install a large and heavy graphics card, you need to use a tool such as MSI
∙
Gaming Series Graphics Card Bolster to support its weight to prevent deformation of
the slot.
∙ When adding or removing expansion cards, always turn off the power supply and
unplug the power supply power cable from the power outlet. Read the expansion
card's documentation to check for any necessary additional hardware or software
changes.

SATA_1~4: SATA 6Gb/s Connectors

These connectors are SATA 6Gb/s interface ports. Each connector can connect to one
SATA device.
⚠
Important
∙ Please do not fold the SATA cable at a 90-degree angle. Data loss may result during
transmission otherwise.
∙ SATA cables have identical plugs on either sides of the cable. However, it is
recommended that the flat connector be connected to the motherboard for space
saving purposes.
