Target Builder
This pink 12+4 pin extension cable converts three 8-pin modular PSU leads into a single 12VHPWR connector for RTX 3090 Ti and RTX 40 series graphics cards. It suits builders who want to keep an existing power supply while upgrading to a newer GPU that requires the 5.0 PCIe power standard. The 30 cm length fits mid-tower and larger cases without excessive slack. Not for builders whose PSU lacks three spare 8-pin ports or who need a native 12VHPWR output.
Thermals and Power
Sixteen AWG conductors wrapped in a high-density PET sleeve meet the UL 1007 wire standard for wear and heat resistance. Gold-plated terminals provide stable contact up to a rated 600 W continuous delivery, covering the 450 W typical draw of an RTX 3090 Ti and the higher demands of RTX 40 series cards. The stiff yet shape-retaining sleeve promotes airflow around the cable run, helping to keep connector temperatures in check during sustained loads.
Bundled Combs
Transparent cable combs are included to align the individual wires into a neat, flat ribbon that holds its bend radius. This makes routing behind the motherboard tray or along a PSU shroud quicker and keeps the pink sleeve visible for a clean aesthetic. No additional software, adapters or mounting hardware are supplied; the combs are the only accessory that changes the installation experience.

Questions about this item
How do I install the 12+4 pin extension cable using my existing 3x 8-pin PSU cables?
Connect each of the three 8-pin connectors from your modular PSU cables to the adapter end, then plug the single 12+4 pin connector into the GPU; the step people miss is fully seating all three 8-pin plugs so the 600W rating is achieved.
Will the PET-sleeved 16AWG cable or gold-plated terminals need replacement over time?
The UL1007 16AWG wires and gold-plated terminals are rated for continuous use with 500-1300W PSUs; the PET sleeve resists wear and heat, so no scheduled replacement is required under normal operation.
At what power draw does the 30cm extension hit its thermal limit during sustained loads?
The cable supports 600W stable output per the 12VHPWR 5.0 design; sustained draws above that level will reach the conductor limit first.
