Important
 
If you install a large and heavy graphics card, you need to use a tool such as MSI 
 to support its weight to prevent deformation of 
the slot.
 
For a single PCIe x16 expansion card installation with optimum performance, using 
the  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.
 
When installing devices in M.2_2, PCI_E2 & PCI_E3 slots at the same time, PCI_E3 
slot will be unavailable, and M2_2 slot only supports PCIe x2.
