Important
For a single PCIe x16 expansion card installation with optimum performance, using
y
the PCI_E1 slot is recommended.
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 and 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.
