Computer Cable Deals & Computer Cables for Sale

Useful if you're connecting older Sony PTZ cameras to a control system via RS-232, since Sony VISCA protocol setups often require this specific adapter to bridge the camera's Mini DIN 8-pin port to a standard RJ45 connection. Buy Now at Newegg

Useful if you have a Toshiba laptop with a damaged or failing DC power port, since replacing the jack entirely can be costly and this cable lets you bypass the original connector without opening the chassis. Buy Now at Newegg

Monoprice is a well-regarded budget-friendly networking brand, and Cat6A supports 10Gbps speeds up to 100 meters, making this a solid pick for home lab setups, office runs, or anyone future-proofing their wired network. At $110, the 5-pack is $17 off the $127 list price. Buy Now at Newegg

Useful for outdoor runs or anywhere the connection point might be exposed to moisture, dust, or debris, since the weatherproof housing keeps the RJ45 joint protected rather than leaving it vulnerable at the splice. Buy Now at Newegg

Useful if you're running a graphics card that requires two 8-pin power connectors but your power supply only has a single 6-pin output, letting you split one cable into two without buying a new PSU. Buy Now at Newegg

Useful if you're building or upgrading multiple budget systems where the PSU has an extra EPS/CPU 8-pin connector but the GPU requires 6-pin PCIe power, letting you adapt without buying a new power supply. The 10-pack makes sense for a small lab, repair shop, or anyone doing several builds at once. Buy Now at Newegg

Useful if your power supply has multiple 8-pin PCIe connectors but your newer GPU (like an RTX 4000 series card) requires a single 16-pin (12VHPWR) connector, as it consolidates those cables into one tidy connection. Buy Now at Newegg

Useful if your GPU doesn't physically fit in your case's primary PCIe slot and you need to reposition it slightly, or if you're building a vertical GPU mount setup. Buy Now at Newegg

A short adapter-length cable for tight spaces where your Mini DisplayPort connection needs a bit more reach, like behind a monitor or inside a desk-mounted setup. Buy Now at Newegg

Lets you connect a GPU that requires an 8-pin PCIe power connector to a power supply that lacks one, by pulling from two SATA ports instead — a practical workaround for older PSUs during a budget build or upgrade. Buy Now at Newegg

Handy to keep around if you're running an older PSU with separate 4-pin connectors but need to power a modern GPU that requires an 8-pin input. Buy Now at Newegg

Useful if your power supply only has 6-pin PCIe connectors but your GPU requires two 8-pin inputs, since it lets you bridge that gap without replacing the PSU. Buy Now at Newegg

Useful if you're running multiple GPUs or adding a second graphics card and need to split a single PCIe connector into two without buying a new PSU. Buy Now at Newegg

Useful if your power supply only has one 8-pin PCIe connector but your GPU requires two, letting you split a single cable into two connections without buying a new PSU. Buy Now at Newegg

Useful for GPU upgrades where your power supply has open SATA connectors but lacks a dedicated 8-pin PCIe power connector, letting you avoid buying a new PSU. Buy Now at Newegg

Useful if your motherboard's fan headers are too far from where your fans are mounted, or if you need a bit more slack to route cables cleanly behind the panel. Buy Now at Newegg

Useful if you're routing fans to a controller or motherboard header that's out of reach, since these give you the extra length without needing to reroute cables through the whole build. Buy Now at Newegg

Useful if you have more fan headers than your motherboard can accommodate, letting you run two 3-pin fans from a single header without adding a separate fan controller. Buy Now at Newegg

A 10-pack makes sense for IT departments, schools, or anyone setting up multiple workstations that still rely on VGA displays, since buying individually would cost considerably more per cable. Buy Now at Home Depot
