12+4 Pin PCIe 5.0 Extension Cable

This 12+4 pin PCIe 5.0 extension cable converts three 8-pin modular PSU cables into a single 16-pin connector. It uses 16AWG UL1007 wire with gold-plated terminals and a high-density PET sleeve. The 30cm length includes transparent cable combs for tidy routing.

Suited for RTX 3090 Ti and 40-series cards

Builders upgrading to a 12VHPWR graphics card without replacing their power supply will find this adapter useful. It supports stable output up to 600W for cards that typically draw 450W. Buyers whose PSU lacks three 8-pin modular outputs or who need a native 12VHPWR cable should look elsewhere.

Check PSU modular ports and case clearance

Verify that your power supply provides three separate 8-pin modular cables rated for the combined load. Ensure the 30cm extension reaches your graphics card without tension and that the PET-sleeved cable fits your chassis routing channels.

Questions about this item

My PSU only has three 8-pin PCIe cables — can I use them with this 12+4-pin extension?

Yes, the extension converts three 8-pin modular cables into a single 12+4-pin connector for RTX 3090 Ti and RTX 40-series cards.

Will the 30 cm length reach from my PSU to a vertically mounted RTX 4080?

The cable measures 30 cm (11.8 in) and includes transparent combs to route and hold the bend neatly in tight chassis space.

How do I verify the gold-plated terminals are making full contact after installation?

Seat each 8-pin and the 12+4-pin connector until the latches click, then confirm the GPU powers on and runs stable under load.
