Important
y
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.
y
For a single PCIe x16 expansion
card installation with optimum
performance, using the
PCI_E2
slot
is recommended.
y
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.
