 ⚠
Important
 ∙
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.
 ∙
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.
PCI_E1  PCIe 3.0/ 4.0 x16 (CPU)
PCI_E3  PCIe 3.0 x1 (PCH)
PCI_E4  PCIe 3.0 x1 (PCH)
PCI_E2  PCIe 3.0 x1 (PCH)

SATA device.
 ⚠
Important
 ∙
Please do not fold the SATA cable at a 90-degree angle. Data loss may result during 
transmission otherwise.
 ∙
SATA cables have identical plugs on either sides of the cable. However, it is 
recommended that the flat connector be connected to the motherboard for space 
saving purposes.
