Computer Cable Deals & Computer Cables for Sale

A short DisplayPort extension cable like this is useful when your monitor's port is recessed or your existing cable just barely falls short of reaching your GPU. Buy Now at Newegg

Handy for builds where your power supply has fewer PCIe connectors than your GPU requires, letting you run dual 6+2-pin connections off a single 6-pin output. Buy Now at Newegg

Handy for tight server rack or AV cabinet installations where a straight cord would strain the connector or block adjacent ports, the 90-degree plug keeps cables routed flat against the equipment. Buy Now at Newegg

A longer power cord is useful when your monitor is positioned far from an outlet or when your current cable is too short to route cleanly behind furniture. Buy Now at Newegg

Designed for enterprise and data center networking, this 40GbE QSFP+ transceiver handles intermediate-reach connections up to 1.4km over single-mode fiber, which suits IT teams looking to extend links between buildings or across a campus without pulling new cabling. Buy Now at Newegg

Useful if you're building or upgrading a PC and need an extra 8-pin power connector to reach your graphics card without stressing the original cable routing. Buy Now at Newegg

Designed for short-range, high-speed connections between network switches and servers, this 10-meter direct attach copper cable is a cost-effective alternative to fiber optic transceivers when your equipment supports SFP ports and your runs stay within 10 meters. Buy Now at Newegg

A direct-attach copper cable for connecting 10GbE switches, routers, or servers at short distances, typically within the same rack or adjacent racks in a data center. Cheaper and lower-latency than optical transceivers, this is a straightforward buy if you're building or expanding a 10G network and need reliable short-run connectivity. Buy Now at Newegg

Handy for GPU upgrades where your power supply only has one 8-pin PCIe connector but your graphics card requires two, saving you from buying a new PSU just to meet the power connector requirement. Buy Now at Newegg

Handy for older motherboards with an open 9-pin USB header, this cable lets you add two USB 2.0 ports to the back of your case without buying a new hub or PCIe expansion card. Buy Now at Newegg

A short 90-degree C13-to-C14 cable is useful when you're working in a tight rack or cabinet where a standard straight cord would put strain on the connector or block airflow — the angled end lets you route cables closer to the wall or panel. Buy Now at Newegg

Useful for GPU riser builds or vertical GPU mounting setups where your graphics card needs to connect to a PCIe slot that isn't directly accessible on the motherboard, and the 4.0 spec means you won't bottleneck a modern card the way older 3.0 risers can. Buy Now at Newegg

Handy for PC builders who need to run multiple case fans from a single motherboard header without adding a full fan controller. Buy Now at Newegg

Handy for connecting 4-pin Molex PC fans to a USB port when you've run out of available power connectors on your PSU, or if you're powering a fan outside of a traditional PC build. Buy Now at Newegg

A short flat patch cable like this is useful when you need a tidy connection between two nearby devices, like a router and a wall outlet, without a bulky round cable bunching up behind your setup. Buy Now at Newegg

A short Cat6A patch cable works well for connecting a router to a modem, a PC to a wall port, or any device where you want a tidy, minimal-length run rather than coiling up excess cable. At $13, that's about $2 off the $15 list price. Buy Now at Newegg

Handy to have around if you're building or upgrading a PC and need to improve wireless signal strength, particularly when your motherboard's included antennas are underperforming or missing entirely. Buy Now at Newegg

Designed for 10 Gigabit Ethernet or SONET/SDH networking over multimode fiber, this SFP+ transceiver is a straightforward drop-in module for switches, routers, or server NICs that need a short-range optical link without the cost of buying OEM-branded hardware. Buy Now at Newegg

Useful if your motherboard has limited fan headers but you need to run multiple case fans from a single connection, keeping them all synced to the same PWM speed signal. Buy Now at Newegg
