PCI_E1~3: PCIe Expansion Slots
PCI_E1: PCIe 4.0 x16 (From CPU)
PCI_E2: PCIe 3.0 x1 (From B660 chipset)
PCI_E3: PCIe 3.0 x4 (From B660 chipset)
Important
If you install a large and heavy graphics card, you need to use a tool such as MSI
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.
