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.
∙ 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.
When installing devices in M.2_2, PCI_E2 & PCI_E3 slots at the same time, PCI_E3
∙
slot will be unavailable, and M2_2 slot only supports PCIe x2.
