Apple PCIE-5.0-CABLE-180 Extension Cable

The Apple PCIE-5.0-CABLE-180 is a 30 cm internal power extension that converts a single 12+4 pin 12VHPWR male connector into three 8-pin (6+2) PCIe female connectors. It is built with 16AWG and 24AWG tinned copper wire and rated for up to 600 W of continuous power delivery. The kit includes four cable combs to help keep the wiring tidy inside a custom build. This extension is intended for PCIe 5.0 graphics cards such as the RTX 3090 Ti, 4070 Ti, 4080 and 4090.

Suited For And Not Suited For

Builders who need a clean 12VHPWR connection and have a modular power supply with three spare 8-pin PCIe cables will find this extension a direct fit. It also suits anyone wanting a 30 cm reach with included combs for neat routing. Buyers whose PSU offers fewer than three 8-pin PCIe outputs cannot use this cable, as all three female connectors must be populated. It is not suitable for the older 12-pin connector found on the RTX 3090 series, and it does not plug directly into a power supply — it only extends existing modular cables.

Capacity And Headroom

The cable handles up to 600 W, which covers the power draw of the RTX 4070 Ti, 4080 and 4090 under normal gaming and compute loads. The 16AWG conductors and alloy copper terminals keep voltage drop low across the 30 cm length, so the connection remains stable even at sustained high load. Headroom runs out if the graphics card spikes above the 600 W rating or if the power supply itself cannot deliver the required wattage through three separate 8-pin cables. A 1000 W PSU is noted as a practical minimum for the highest-end cards.
