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.
