Pros & Cons

Pros

  • ✓ Covers all three visible runs: 24-pin ATX, 8-pin EPS, dual 6+2-pin PCI-E
  • ✓ 18AWG copper conductors, thicker than the 20AWG used in many budget extension kits
  • ✓ Pre-bent cables hold their curve instead of springing back against the case tray
  • ✓ Heat-shrink-free ends keep the sleeve uniform all the way to the connector
  • ✓ Cable combs included, so no separate purchase to align the strands

Cons

  • ✗ Adds a second connector junction to every run, which needs a firm seat
  • ✗ Extra cable length has to be hidden, so it needs room behind the motherboard tray
  • ✗ Fixed white/black/sky blue colorway clashes with red or amber-accent builds

Manufacturer description

The Formulamod PSU Cable Extension Kit gives your build the sleeved-cable look without replacing your power supply. The kit covers the three runs that show through a tempered-glass side panel: a 24-pin ATX, an 8-pin EPS, and dual 6+2-pin PCI-E leads for your GPU. Each run uses 18AWG copper conductors under a sleeved exterior, and the cables ship pre-bent so they hold their curve in the case instead of springing back toward the tray. A heat-shrink-free termination keeps the sleeve uniform right up to the connector, and the included combs let you lock the strands into even rows behind the…

SpecPicks Verdict

SpecPicks scored Formulamod PSU Cable Extension Kit 18AWG Sleeved using a rating × review-volume × price-fit model applied to published specs and reviews across the accessories category. Formulamod's accessories lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for accessories of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.

Frequently Asked Questions

Do these replace my power supply cables or plug into them?

They plug into them. This is an extension kit, so the original PSU cables stay connected to the power supply and these extend the last few inches to the motherboard and GPU.

Will this kit fit 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. Confirm your PSU uses standard ATX pinouts before ordering.

What gauge wire is used, and does it matter?

18AWG copper. Heavier gauge than the thin wire in many budget kits, which is what the listing points to for stable power transmission over the extension run.

Are cable combs included or do I buy them separately?

Combs are included. They hold the individual wires in even rows so the 24-pin run looks flat instead of fanned out behind the glass.
