This episode covers the various internal interfaces found on a motherboard and what role each plays in system function. We begin with SATA connectors, explaining their use in connecting storage devices such as hard drives and optical drives. From there, we move to PCIe slots—detailing how different lane configurations like x1, x4, x8, and x16 are used for graphics cards, network adapters, and expansion cards.

We also explore power connectors such as 24-pin ATX and 8-pin CPU connectors, and explain how improper connection or insufficient power delivery can lead to system instability. This episode gives you the vocabulary and visual memory cues needed to identify and troubleshoot motherboard interface issues, both on the exam and in hands-on environments.
