Important
If you install a large and heavy graphics card, you need to use a tool such as MSI
y
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
y
the PCI_E1 slot is recommended.
When adding or removing expansion cards, always turn off the power supply and
y
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.
