SATA 3.0 Device Installation:
- Connect one end of a SATA data cable to one of the three Serial ATA 3.0 ports on the motherboard.
- Connect the other end of the SATA data cable to your SATA hard drive or SSD.
- Connect a SATA power cable from your power supply to the SATA device.
4. Expansion Card Installation
Install graphics cards or other expansion cards into the PCI Express slots.
- Locate the PCI Express x16 slot (for graphics cards) and the PCI Express x1 slot.
- Align the expansion card with the chosen slot and press down firmly until it is seated correctly.
- Secure the card with a screw to the computer case.
5. Power Connections
Connect the main power cables from your power supply to the motherboard.
- Connect the 24-pin ATX power connector to the main power socket on the motherboard.
