Pci_E1~3: Pcie Expansion Slots; Sata1~4: Sata 6Gb/S Connectors - MSI A320M BAZOOKA Manual

PCI_E1~3: PCIe Expansion Slots

Important
If you install a large and heavy graphics card, you need to use a tool such as MSI
y
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
y
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.

SATA1~4: SATA 6Gb/s Connectors

These connectors are SATA 6Gb/s interface ports. Each connector can connect to one
SATA device.
Important
Please do not fold the SATA cable at a 90-degree angle. Data loss may result during
y
transmission otherwise.
SATA cables have identical plugs on either sides of the cable. However, it is
y
recommended that the flat connector be connected to the motherboard for space
saving purposes.
