Who it fits

Key specs explained for Thsion cables

25 inches length

This length gives you enough slack to route cables cleanly inside your case without pulling tight against components. It is long enough to reach from most modular power supply positions to the graphics card, reducing strain on the connectors. If your case has tight cable management channels, you can trim excess or zip-tie the slack neatly. This size suits standard ATX mid-tower cases well.

18 AWG

AWG stands for American Wire Gauge. A lower number means a thicker wire. 18 AWG is thicker than standard 20 AWG cables, allowing it to carry more current with less resistance and heat buildup. This specification supports stable power delivery to high-end graphics cards. When shopping, look for 18 AWG or lower for heavy-duty GPU power needs rather than thinner wires.

10A

This rating indicates the maximum current each wire can safely carry is ten amperes. Since a standard 8-pin PCIe connector has multiple wires, the total capacity is higher. This rating ensures the cable handles the power draw of modern GPUs without overheating. It matches the typical requirements for most desktop graphics cards. Check your GPU power specs to ensure this current limit meets your hardware demands.

300V

This voltage rating means the insulation can withstand up to three hundred volts without breaking down. This provides a safety margin well above standard household or computer internal voltages. It protects against electrical arcing or short circuits inside your case. This rating is standard for PC components. You do not need to worry about voltage limits for typical desktop power supply usage.

6+2 Pin

This connector type combines a fixed six-pin block with a detachable two-pin block. It allows the cable to fit into both standard six-pin and eight-pin GPU sockets. This flexibility ensures compatibility with a wide range of graphics cards. You can plug in the extra two pins if your card requires full eight-pin power. This design is the industry standard for modern PCIe power connections.

Build Quality And Dimensions

The listing states the cables are constructed from 18 AWG tinned copper wire. This gauge and material choice supports a current rating of 10A and a voltage rating of 300V. Thicker 18 AWG conductors reduce electrical resistance compared to thinner wires. This helps maintain stable power delivery to your graphics card under load. The tinned copper plating protects against corrosion, which can degrade connections over time. This is a practical detail for longevity in enclosed cases.

According to the listing, each cable measures 25 inches in length. This specific length provides enough slack for clean routing inside most PC cases. It allows you to connect the power supply to the GPU without excessive bending or tension. The cable width is listed as 1 inch, and the height is also 1 inch. These dimensions suggest a standard profile that should fit comfortably in typical cable management channels or behind motherboard trays.

The product is sold as a 2-pack. This means you receive two identical cables. This is useful if your graphics card requires dual 8-pin connections or if you need a spare. The connectors are male-to-male, with one end designed for the EVGA PSU and the other terminating in a 6+2 pin interface. This modular design ensures you can detach the cable if needed, though the listing notes it is specific to EVGA units only.

Installation And Daily Use

Setup requires careful attention to compatibility and connection order. These cables are designed exclusively for EVGA modular power supplies. You must verify your unit matches the listed models, including the Super Nova G, G2, G3, G5, G6, GA, GM, GT, P, P2, P3, P5, P6, and T series. Using them with other brands will not work and may cause issues. When installing, insert the single male interface into the corresponding VGA port on the EVGA power supply first. Then, connect the 6+2 pin male end to your graphics card. Incorrect installation can damage your GPU, so ensure the fit is secure. The 6+2 pin design allows the cable to work with standard 8-pin connectors on modern cards. This configuration supports a wide range of graphics cards, from older GTX and RX models to newer RTX 30 and 60 series units. The 18 AWG tinned copper wire handles up to 10A at 300V, providing stable power delivery during daily use. The 25-inch length offers sufficient slack for clean cable management inside your case. You can route the wires without tension, which helps maintain airflow and reduces strain on the connectors. The package includes two cables, allowing you to power dual-slot GPUs or replace lost units. The 2-year warranty covers manufacturing defects. If you encounter questions during setup, the brand offers professional support. This product is a straightforward replacement solution for EVGA users needing extra PCIe power connections. It does not offer universal compatibility, so stick to the specified power supply list for safe operation.

Before You Buy This Cable

You need to confirm your power supply is an EVGA model before ordering. These cables do not work with other brands. Check your unit against the listed Super Nova series, including G, G2, G3, G5, G6, GA, GM, GT, P, P2, P3, P5, and P6 models. Using them with incompatible units can damage your hardware. You must also ensure your graphics card accepts a 6+2 pin PCIe connector. Most modern cards do, but older models may require different adapters. Since this is a replacement part, you will need to open your case to swap the old cable. Keep your workspace clean to avoid losing small connectors. This product fits as a specific fix for EVGA owners who lost or broke a cable. It does not replace your power supply. It only extends the connection from the PSU to your GPU. If you need a new power supply entirely, look at the broader UPS and PSU options instead.

Check before you buy

• Verify your power supply is an EVGA Super Nova model.
• Confirm your GPU uses a 6+2 pin PCIe power connector.
• Check that the 25-inch length fits your case layout.
• Ensure you have tools to open your computer case.
