Corn Electronics 18AWG Purple Internal Power Cable Kit 300mm

Kit contents and target builds

This cable kit supplies a 24-pin ATX extension, an 8-pin EPS cable, two 8-pin PCIe cables and two 6-pin PCIe cables, each 300 mm long with black connectors. It suits builders who want a consistent purple accent inside a standard desktop tower. The 18 AWG conductors and triple-layer weave are rated for typical power-supply loads. Buyers needing cables for server backplanes or proprietary laptop power bricks should look elsewhere.

Installation notes and common issues

Route each cable from the power supply to the motherboard or graphics card, then snap the supplied combs onto the wires to keep bundles tidy. The stiff weave can resist tight bends behind the motherboard tray, so plan generous curves rather than sharp folds. A frequent mistake is leaving the EPS connector half-seated; press until the latch clicks to avoid boot failures. The fixed 300 mm length may fall short in extended-height cases or when the PSU mounts at the bottom with a long GPU run.

Compatibility checklist

Verify that your power supply uses standard ATX, EPS and PCIe pinouts — the kit does not adapt proprietary modular headers. Confirm the 300 mm reach covers the distance from your PSU sockets to the 24-pin, CPU and graphics-card connectors in your specific case layout. Ensure the purple sheathing matches your colour scheme, as no alternative colours are included.
