PCIe 5.0 12VHPWR cable for RTX 3090 Ti.

This 16-pin GPU power cable connects PCIe 5.0 graphics cards to modular power supplies. It is built for RTX 3090 Ti, 4080 and 4090 models that require a 12+4 pin connector. The cable only works with ASUS, EVGA or Seasonic PSUs that have three free 8-pin (6+2) ports. It is not suitable for the older 12-pin RTX 3090 series.

16 AWG tinned copper handles 600 W

The cable uses 16 AWG tinned copper wire rated for up to 600 W output. Alloy copper terminals with tin plating provide a secure connection. Four included cable combs keep the three 8-pin branches and the 16-pin end neatly arranged. Proper seating of all three PSU connectors is required to avoid system damage.

70 cm length with four combs for tidy routing

At 70 cm the cable reaches from a bottom-mounted PSU to a top-mounted GPU in most full-tower cases. The four combs align the individual wires, reducing clutter and improving airflow around the graphics card. Three 8-pin (6+2) plugs on the PSU side must all be populated, so the power supply needs three available PCIe ports.

Questions about this item

How do I install the 12VHPWR cable and which step do people get wrong?

Plug the three 8-pin (6+2) connectors fully into the PSU first, then seat the single 16-pin (12+4) connector into the RTX 3090 Ti, 4080 or 4090; the common mistake is using fewer than three PSU ports, which can damage the system.

What maintenance or replacement will this cable need later?

The 16 AWG tinned-copper wires and alloy-copper terminals are rated for continuous 600 W operation; no scheduled maintenance is required, but inspect the connectors if you ever reseat the GPU or PSU.

What limit appears first under sustained load?

The cable is specified for a maximum of 600 watts; sustained draws above that will hit the thermal and current limit of the 16 AWG conductors before any other factor.
