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.
Installing SLI graphics cards
For power supply recommendations for SLI configurations, Please refer to the user
guide of your graphics card to make sure you meet all the system requirements.
To install SLI graphics cards:
1. Turn off your computer and disconnect the power cord, install two graphics cards
into the PCI_E1 and PCI_E3 slots.
2. Connect the two cards together using the SLI Bridge Connector .
