Overview of Components

PCI_E1~5: 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.

∙

The PCIe x1 slots can not be used simultaneously. PCI_E2 will be unavailable when

installing the PCIe card in PCI_E4 slot.
