∙

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.
