Key takeaways
- Hole Diameter: Match the comb hole to your cable gauge—3.5 mm suits 16 AWG sleeved wires, while 3 mm fits tighter 18 AWG runs without wobble.
- Pin Configuration Coverage: Verify the kit includes every connector you need (24-pin, 8-pin EPS, 6-pin PCIe, 12VHPWR) so you are not buying supplemental packs later.
- Material and Finish: ABS plastic is lightweight and affordable; zinc alloy or silver-plated combs add heft and resist flexing on thick paracord sleeves.
- Color and Visibility: Pick black for stealth builds, white for themed rigs, or semi-clear combs when RGB lighting beneath the PSU shroud should remain visible.
- Quantity per Kit: Count your total cable runs before purchasing; a 24-piece set covers most ATX builds, but dual-GPU or custom-loop setups may need 30-plus combs.
What's inside
The Sirlyr Black 24-PCS PSU Cable Combs Kit is our best overall pick for clean PSU routing, offering unmatched connector coverage at 3.5 mm spacing, while the EZDIY-FAB Shield Cable Comb Kit earns runner-up honors for its reliable fit across 16 AWG and 18 AWG extensions.
Untidy PSU cables ruin an otherwise flawless build, block airflow, and make future upgrades a nightmare. Cable combs solve this by locking individual conductors into parallel rows before they reach the motherboard or GPU. This guide covers six proven kits, explains exactly what to look for in hole diameter and pin compatibility, and helps you match the right comb set to your specific wiring layout—whether you are sleeving a 12VHPWR connector or tidying a legacy Molex chain.

The Best Cable Combs for Clean PSU Routings Reviewed
Best Overall: Sirlyr Black 24-PCS PSU Cable Combs Kit
With four 12VHPWR combs, four 24-pin combs, and sixteen 8-pin combs, this kit handles every connector on a modern ATX 3.0 build in one purchase. It is the ideal choice for enthusiasts who want a single, comprehensive solution without mixing brands.
Best Budget: EZDIY-FAB Shield Cable Comb Kit
The shielded channel design grips 16 AWG and 18 AWG extensions firmly, making this an excellent entry point for first-time builders who need reliable organization without a premium price tag. The inclusion of 6-pin combs adds versatility for older GPU power leads.
Best Premium: SIRLYR Silver-Plated Zinc PSU Cable Combs Kit
Machined zinc alloy with a mirror-silver finish elevates any open-frame or glass-panel build. This set is aimed at modders who treat cable management as a visible design element and want hardware that will not yellow or crack over time.
Best for RGB Showcase Builds: LINKUP PSU Cable Extension Combs (Semi Clear)
The translucent polycarbonate body allows addressable RGB glow from nearby strips to pass through, keeping illumination uninterrupted. Showcase builders and streamers who photograph their rigs will appreciate how the combs disappear visually while keeping wires perfectly parallel.
Best for White-Themed Builds: upHere 24-Piece Cable Comb Set (White)
Color-matched white combs at 3.4 mm spacing blend seamlessly with white paracord sleeves and pastel case interiors. This set suits builders committing to an all-white or snow-themed aesthetic who cannot tolerate black plastic breaking the color story.
Frequently Asked Questions
Do cable combs fit all PSU cables universally?
No. Comb hole diameter must match your wire gauge. Most 16 AWG sleeved cables need 3.5 mm holes, while thinner 18 AWG or stock rubber-sheathed wires may fit 3 mm combs. Always check the product listing for AWG compatibility before ordering.
Can I use cable combs with 12VHPWR connectors?
Only if the kit explicitly includes 12VHPWR combs, which use a tighter 12- or 16-pin layout. The Sirlyr 24-PCS kit and select Formulamod sets cover this standard; generic 8-pin-only kits will not fit.
Are metal combs better than plastic ones?
Metal combs such as zinc alloy resist warping under heat and add a premium look, but they cost more and can scratch delicate sleeve material if installed carelessly. High-quality ABS plastic combs perform identically for routing and are gentler on paracord.
How many combs do I actually need for a typical gaming PC?
A standard single-GPU ATX build uses roughly 12 to 16 combs across the 24-pin, two 8-pin EPS, and two PCIe power runs. Dual-GPU or custom-loop systems with multiple extensions may require 24 or more.
Final Thoughts
For most builders, the Sirlyr Black 24-PCS PSU Cable Combs Kit delivers the broadest connector coverage and the best value in a single box. If budget is the priority, the EZDIY-FAB Shield Cable Comb Kit provides dependable organization at a lower entry price. And for those who want their cable management to double as a design statement, the SIRLYR Silver-Plated Zinc kit turns functional routing into a genuine visual upgrade. Whichever you choose, pairing combs with quality sleeved extensions and a PSU shroud will give you the clean, airflow-friendly interior your build deserves.
