PCIe Slots

PCIe (Peripheral Component Interconnect Express) slots are the backbone for high-speed expansions. Available in x1, x4, x8, and x16 sizes, they support GPUs, SSDs, and network cards. PCIe 5.0 dominates in 2026, offering up to 128 GB/s bandwidth for ultimate performance.

  • Ideal for gaming rigs with top GPUs
  • Backward compatible with older PCIe versions

M.2 Slots

Perfect for boot drives
Check board specs for slot count

M.2 slots enable ultra-fast NVMe SSD storage. Common on motherboards, they support PCIe and SATA interfaces with key types like M-key for SSDs. 2026 sees PCIe 5.0 M.2 hitting 14,000 MB/s reads.

USB Ports

SATA Ports

SATA ports connect HDDs and older SSDs at 6 Gbps. While PCIe NVMe outpaces them, SATA remains for bulk storage in 2026 builds.

  • 6 ports common on ATX boards
  • Redundant for legacy drives

RAM Slots

Usually 4 slots per board
Match speeds for stability

DIMM slots for desktop RAM support DDR5 in 2026, with speeds up to 8,000 MT/s. Quad-channel configs maximize bandwidth for content creation.
