Cable Matters 8 Pin GPU Power Cable
The Cable Matters cable converts an 8-pin EPS/ATX power input to a 6+2-pin PCIe/GPU output. It is designed for Corsair Type 3 and Type 4 pinouts, and is not compatible with certain EVGA PSUs or other brands with differing pinouts. Pin 4 on the PSU side is unused, while Pin 5 on the GPU side is double-wired to help maintain stable 12V delivery. It is suitable for powering high-demand GPUs and provides flexibility for varied PCIe configurations. Always verify your PSU’s connector shape and pinout before purchase.
AC 2 Prong Power Cord 3FT C7 Replacement
This 2-prong C7 power cord is suitable for a wide range of devices including TVs, consoles, monitors, and other electronics that use a two-pin plug. While not a PCIe or CPU power cord, it complements setups that require a basic, high-quality power connection for supplementary gear in a PC environment or home theater system.
SATUY 2 Pack CPU 8 Pin ATX Extension Cable
Satuy offers a 9-inch 8-pin extension (4+4) for CPU power, with a detachable end that allows conversion between EPS ATX 8-pin and P4 4-pin configurations. The extension uses tinned copper with a flexible PVC jacket and a locking design to prevent accidental disconnection. It’s specifically intended for extending CPU power rather than PCIe, and helps tidy cable routing when space is tight behind the motherboard tray.
J&D EPS 8 Pin Power Extension Cable
This J&D EPS 8 Pin Extension Cable provides one 8-pin ATX 12V male and one 8-pin female connector, extending the CPU power lead by 12 inches. It uses a PVC flexible jacket and 18 AWG tinned copper for reliability. The locking design helps prevent disconnections, keeping power delivery stable during sensitive CPU operations and overclocking scenarios where extra cable slack is beneficial.
SinLoon 8-Pin Extension Cord PCIe Cable
SinLoon’s extension converts the original 8-pin PCIe connection to a 90-degree elbow, aiding cable routing and aesthetic inside the case. It uses 18 AWG wire and a locking joint to prevent accidental disconnections. The cable is suitable for PCIe power delivery to GPUs, offering a cleaner build with fewer cable overlaps in tight builds.
YEZriler 8 Pin PCIe Cable For EVGA
YEZriler provides an 8-pin PCIe cable designed for EVGA power supplies, with a PCIe 8-pin male to 6+2 pin PCIe male configuration. It emphasizes correct port compatibility—ensuring the 8-pin end from the PSU fits a PCIe 8-pin socket rather than a CPU 8-pin. The 6+2 end can adapt to both 6-pin and 8-pin GPUs. It is not compatible with Corsair or certain non-EVGA systems, so compatibility verification is essential before purchase.
Buying Guide
Key purchase considerations for 8-pin cables and extensions include compatibility, flexibility, and safety. First, confirm the pinout of your PSU and GPU or motherboard to avoid power delivery issues. Some cables are designed for CPU power (EPS 8-pin), while others serve PCIe GPU connections; using the wrong type can cause power faults or hardware damage.
Second, evaluate the connector form factor. Extensions with detachable segments or 4+4 configurations offer versatility for different motherboard and PSU brands. Locking features help prevent accidental disconnections during operation, which is particularly important in high-performance builds.
Third, consider the cable quality and gauge. 18 AWG conductors are common for PCIe power leads, offering sufficient current capacity while keeping cables manageable in length and flexibility. Flexible jackets and secure shielding also reduce heat buildup in dense builds.
Fourth, plan for future upgrades. If you anticipate shifting between brands or upgrading GPUs, selecting adapters or extensions with universal compatibility (within safe specs) can save time and reduce clutter. However, never force a mismatch; only use cables that explicitly match your device’s pinout.
Finally, ensure safe handling and installation. Disconnect power before routing cables, secure all connectors fully, and verify that no cables press against fans or hot components. For EVGA, Corsair, or other specific PSUs, double-check whether a given 8-pin cable is rated for that brand or if it’s explicitly listed as incompatible.
