Important
If you install a large and heavy
y
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.
For a single PCIe x16 expansion
y
card installation with optimum
performance, using the PCI_E2 slot
is recommended.
When adding or removing expansion
y
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.
