PCI_E1~4: PCIe Expansion Slots

BAT1
⚠
Important
∙ PCI_E3 will be unavailable when installing M.2 SSD in the M2_2 slot.
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.
∙ For a single PCIe x16 expansion card installation with optimum performance, using
the PCI_E1 slot is recommended.
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.

SATA1~6: 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.
∙ SATA1 will be unavailable when installing M.2 SATA SSD in the M2_1 slot.
