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.
∙ 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.
