PCI-e 5.0 GPU Extension Cable

This white sleeved extension cable converts a single 16-pin 12VHPWR male connector into three 8-pin 6+2 female connectors. It is built for graphics cards that use the 12+4 pin receptacle such as the RTX 3090 Ti 4070 Ti 4080 4090. The 30 cm length adds reach inside the case while four included acrylic combs keep the wires aligned.

Builders with 12+4 pin GPUs and three free PSU ports

The cable suits systems where the power supply offers three separate 8-pin PCI-e outputs and the graphics card requires a 12+4 pin input. It will not work with the older 12-pin only RTX 3090 Founders Edition. Buyers whose PSU has fewer than three 8-pin ports cannot use this extender safely.

600 W maximum power rating

The 16 AWG tinned copper conductors are rated for up to 600 W continuous delivery. This single figure determines whether the cable can handle the graphics card’s peak draw without voltage drop or overheating.

Questions about this item

Does the box include the 12+4 pin GPU connector and the three 8-pin PSU connectors, or must any of those be purchased separately?

The cable comes with a 12+4 pin male connector on one end and three 8-pin (6+2) female connectors on the other, plus four acrylic cable combs; no additional connectors are needed.

The listing mentions RTX 3090 Ti, 4070 Ti, 4080 and 4090 — which of those GPUs is this 12+4 pin cable actually built for?

It is built for any GPU that uses a 12+4 pin (12VHPWR) socket, so it fits the RTX 3090 Ti, 4070 Ti, 4080 and 4090, but not the original 12-pin RTX 3090.

What does the 600 W rating mean when the cable is installed in a system with a high-end graphics card?

The 16 AWG tinned copper wires and alloy copper terminals are rated to deliver up to 600 W through the three 8-pin PSU connectors, provided all three are plugged into the power supply.
