How to Choose Sleeved Cables
The two questions that decide everything: are you extending or replacing, and which connectors do you actually need? Extensions are universal and beginner-safe; replacements must match your PSU model exactly. After that it's colour, length and whether you want cable combs for that flat, parallel look. The guide below walks through it.
Extensions plug onto your existing PSU cables and work with any power supply — the safe, simple choice for the sleeved look. Replacement cables swap your PSU's cables entirely for a cleaner result with no doubled-up connectors, but they must match your exact PSU model. If you're not certain of your PSU's pinout, choose extensions.
Modular power supplies use different PSU-side pinouts between brands and sometimes between a single brand's ranges. A connector that physically fits is not proof it's wired the same way — using a replacement cable meant for another PSU can short components. Only fit replacement cables confirmed for your specific PSU model; extensions sidestep this because they use the standard device-side connectors.
Most builds need three: the 24-pin ATX motherboard cable, the 8-pin (4+4) EPS cable for the CPU, and one or more 6+2-pin PCIe cables for the GPU. Newer high-end cards may use a 12VHPWR / 12V-2x6 connector instead — check your GPU. Buy a set that covers what your board, CPU and graphics card actually require.
Sleeved cables and extensions come in set lengths; pick enough to route behind the motherboard tray and up to each connector without strain, but not so much that excess bunches up. Larger cases need longer runs. Plan the path from the PSU shroud to each connector before choosing a length so the cables sit flat.
Combs are small clips that hold the individual wires parallel and evenly spaced, which is what gives sleeved cables their crisp, ribbon-like look. Many kits include them; otherwise they're a cheap add-on. They make the biggest visual difference on the wide 24-pin cable that's most visible through a glass panel.
