⚠
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.
