Overview of Components
PCI_E1~4: PCIe Expansion Slots
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.
The PCI_E4 slot will be unavailable, when installing M.2 SSD into M2_4.
The both PCIe x1 slots will be unavailable after you install the M.2 SSD into M2_2
slot in Chipset support mode (default mode).
Please refer to the following PCIe bandwidth configuration table for PCIe & M.2
slots for details.
