Computer Cable Deals & Computer Cables for Sale

Useful for anyone building or upgrading a PC who wants to add more USB 3.0 front-panel ports without buying a new motherboard — it splits a single 19-pin header into two, so you can connect an additional case or hub without running out of headers. Buy Now at Newegg

Useful for connecting microcontrollers, Arduino boards, or other DIY electronics projects where a short, flexible cable with Dupont-style connectors gives you more routing options than a standard USB-B cable. Buy Now at Newegg

Useful for PC builders who want to add a USB-C port to their case's front panel but have a motherboard that only offers a USB Type-E internal header rather than a standard USB-C connector. Buy Now at Newegg

Handy for tidying up short cable runs in a rack or wall-mount setup, particularly if you're organizing patch cables between switches and panels in a tight space. Buy Now at Newegg

Useful for connecting an older USB printer to your network so multiple computers can share it without anyone needing to be physically plugged in or have their machine running as a host. Buy Now at Newegg

Handy to have if you're retrofitting a standard ATX power supply into a Dell desktop that uses a non-standard 6-pin motherboard connector, since Dell has used proprietary power configurations on many of their older systems that won't work with a straight swap. Buy Now at Newegg

A straightforward replacement cable if your HP desktop's power cord gets damaged or goes missing, and the 10-foot length gives you more reach than the standard shorter cords that typically ship with desktop PCs. Buy Now at Newegg

Useful if you're running older Mac Pro or G5 hardware and need to adapt the native 6-pin power connectors to feed a modern 8-pin PCIe graphics card, and the 10-pack format makes sense for shops or builders working across multiple machines at once. Buy Now at Newegg

Useful if your PC case layout requires repositioning your graphics card, either for a vertical GPU mount or to work around clearance issues with large coolers or other components. Buy Now at Newegg

Handy for anyone building out a home network or server rack who wants a clean, permanent wall or panel mount for Ethernet runs instead of loose cables dangling behind gear. Buy Now at Newegg

Useful if your power supply lacks a dedicated PCIe 8-pin connector but has open Molex connectors, letting you run a mid-range graphics card without replacing the PSU. Buy Now at Newegg

A straightforward adapter cable for anyone upgrading to a newer GPU that uses a 10-pin connector on a PSU that only has 8-pin PCI-E outputs, which is a common mismatch when pairing older power supplies with newer graphics cards. Buy Now at Newegg

Useful for anyone upgrading to a newer GPU that requires the 16-pin PCIe 5.0 connector but whose power supply only has the older 8-pin outputs — you get two cables so you have a spare or can run dual adapters across a second build. Buy Now at Newegg

Useful if your PC motherboard is running low on fan headers and you need to power additional case fans directly from a SATA power connector instead. Buy Now at Newegg

A rotating power cord is worth having if you're working in a tight space behind a desk where a fixed plug creates awkward angles or puts strain on the connection point. Buy Now at Newegg

A rotating plug is the practical detail here — it lets you position the cord at an angle when your power strip or outlet is in a tight spot, reducing strain on the connection and making cable management easier behind a desk or entertainment center. Buy Now at Newegg

Monitors occasionally need a replacement power adapter, and this one is listed as compatible specifically with the Acer S243HL, so it's a straightforward option if yours has failed or gone missing. Buy Now at Newegg

Useful if your GPU fan connector doesn't match your motherboard or replacement fan header, letting you avoid buying a new card or fan just because the plug size is wrong. Buy Now at Newegg

Handy for adding front-panel or custom-mounted USB 3.0 ports to a desktop build without buying a new case, as it connects directly to your motherboard's internal 20-pin header. Buy Now at Newegg
