pcie expansion

The pcie expansion tag on WindowsForum.com collects discussion of adding capability to a desktop PC through PCI Express hardware, most visibly the question of how to add USB ports. The tagged thread compares external hubs, monitor hubs, PCIe expansion cards, and unused motherboard headers, weighing bandwidth, power delivery, and available slots. The recurring point is that adding physical ports differs from adding the bandwidth and power those devices actually need, so a keyboard and mouse rarely justify the same card as high-throughput peripherals. It suits readers planning upgrades or troubleshooting connectivity on Windows desktops.
