Computer Cable Deals & Computer Cables for Sale

Multimode fiber patch cables like this are used to connect networking equipment over short to medium distances, and the ST connector type is common in older enterprise and data center environments. At 45 meters, this is a longer-than-average run, so it suits setups where equipment racks or server rooms are spread across a larger space. Buy Now at Newegg

Suited for data centers or network installations that need high-bandwidth fiber runs between switches, patch panels, or transceivers over longer distances. OM4 multimode supports 40G and 100G speeds up to 150 meters, and SC connectors are still common in enterprise and telecom environments. Buy Now at Newegg

Useful if you're connecting fiber optic networking equipment with LC ports, like switches or transceivers, where singlemode cable is required for longer-distance or high-precision signal transmission. The 1-meter length suits rack-mounted gear where the endpoints sit close together. Buy Now at Newegg

Useful if you're running high-speed network connections between switches, servers, or storage equipment over short distances, since OM4 multimode fiber supports 40G and 100G speeds up to 150 meters. Buy Now at Newegg

Buying patch cables in bulk at this length makes sense for rack setups, server rooms, or any structured wiring job where you need short, clean runs between closely spaced equipment without the clutter of excess cable. Buy Now at Newegg

Useful for adding Power over Ethernet to a camera, access point, or other PoE device on a 12V or 24V DC system, like those found in vehicles, boats, or off-grid setups where standard AC-powered injectors aren't an option. Buy Now at Newegg

Primarily used in cryptocurrency mining rigs, this riser card lets you mount a GPU away from the motherboard slot, which is useful when you need to space out cards for airflow or your case layout doesn't allow direct installation. Buy Now at Newegg

Handy to keep around if you have small electronics or accessories that charge via a 4.0mm x 1.7mm barrel connector but you've misplaced the original adapter, since these let you draw power from any USB-A port instead. Buy Now at Newegg

A straightforward solution for older workstations or custom builds where your power supply has 6-pin mini connectors but your GPU requires standard PCIe 6-pin inputs, and buying a 5-pack keeps you covered for multiple builds or future upgrades. Buy Now at Newegg

A handy pickup for anyone retrofitting or replacing graphics cards in older G5-era Mac Pro towers, where the non-standard power connectors make standard PCIe cables incompatible. Getting five in a pack makes sense if you're working on multiple machines or just want spares on hand. Buy Now at Newegg

Useful if you're building or upgrading multiple PCs and need to adapt a standard 6-pin connector to a PCIe GPU power input — buying a 10-pack keeps spares on hand for future builds or replacements without paying per-cable prices. Buy Now at Newegg

Needed if you're running an older PSU with standard 8-pin PCIe connectors and a newer GPU that requires the 12-pin (or 16-pin) power input, like an Nvidia RTX 30 or 40 series card. Most of these adapters bundle two or three 8-pin connectors into a single cable, so your existing power supply works without an upgrade. Buy Now at Newegg

A 10-pack of these splitter cables is useful if you're building or upgrading multiple systems with graphics cards that require 8-pin power connectors but your PSU only has 6-pin outputs, or if you're running a small shop or lab setup where having spares on hand makes sense. Buy Now at Newegg

Useful if you're running an older power supply or connecting legacy components that use Molex connectors to a GPU or other card with a 6-pin PCIe power requirement. Buy Now at Newegg

Handy to have if your power supply only has 6-pin connectors but your GPU requires an 8-pin connection, which is a common situation when pairing an older PSU with a newer graphics card. Buy Now at Newegg

Handy for anyone who needs to recover files from an old desktop or laptop hard drive without putting it back in a machine, since it lets you plug legacy IDE or SATA drives directly into a USB port on your current computer. Buy Now at Newegg

Useful for PC builders who want to clean up cable management or add some visual flair inside a windowed case, since the sleeved extensions give you more length and a tidier look than bare stock cables. Buy Now at Newegg

Handy to keep around if you're building or repairing a PC and need to replace a frayed or broken front panel connector cable, since these small wires are rarely included as spares and can be surprisingly hard to source locally. Buy Now at Newegg

Handy if you're running multiple case fans but only have a limited number of headers on your motherboard, since it lets you run up to four fans from a single connector. Buy Now at Newegg
