Manufacturer description

The Formulamod PSU Cable Extension Kit gives your build the sleeved-cable look without replacing the power supply. The set covers the three runs that show most in a windowed case: a 24 pin ATX, an 8 pin EPS, and dual 6+2 pin PCI-E for the GPU. Each run uses 18AWG copper conductors under a sleeved exterior, and cable combs are included so the individual wires stay evenly spaced instead of fanning out behind the motherboard tray. A pre-bent structure holds its curve after installation, and the heat-shrink-free termination removes the glossy black band you normally see where sleeving meets the…

Formulamod's power supplies lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Frequently Asked Questions

Do these replace my power supply cables?

No. This is an extension kit and must be used together with your original PSU cables. You plug the extensions into the existing cables and route the sleeved section through the visible part of the case.

Will this work with my power supply?

It is designed for standard ATX power supplies with 24 pin ATX, 8 pin EPS, and 6+2 pin PCI-E connectors. Because it extends rather than replaces, PSU-specific pinouts are not a concern, but confirm your supply uses standard connector shapes.

Are cable combs included or do I buy them separately?

Combs are included with the kit. They hold the individual 18AWG wires at even spacing across each run, which is what produces the flat ribbon look rather than a loose bundle.

What wire gauge is used and does it affect power delivery?

The wires are 18AWG copper with a sleeved exterior, specified for stable power transmission. That is the same gauge commonly used in ATX power cabling.
