12VHPWR Extension Cable 16AWG

This 16AWG sleeved extension cable carries the 12VHPWR PCIe 5.0 interface to compatible graphics cards. It connects a male 12+4 pin plug to a female 12+4 pin socket and supports up to 600W. Four pre-installed cable combs keep the nylon-sleeved wires tidy.

Builders using RTX 40-series or RTX 3090 Ti cards

Suits anyone extending a native PCIe 5.0 PSU cable or the bundled 1-to-4 adapter on RTX 3090 Ti, 4070, 4080 or 4090 GPUs. Not for owners of 12-pin RTX 30-series Founders Edition cards. Not for RTX 5090 installations. Do not plug directly into a power supply.

600W maximum power rating

The alloy-copper terminals and 16AWG tinned-copper conductors are rated for 600W continuous delivery. Verify that your PSU and GPU combination stays within this limit before installing.

Questions about this item

Does the 16AWG cable and 600W rating keep heat low during all-day gaming?

The 16AWG tinned copper conductors and alloy copper terminals are rated for 600W continuous output, designed for stable power delivery without frame drops or flickering under sustained load.

What PSU connection does the 12VHPWR extension need to work?

It is an extension only — plug it between the GPU and either a native PCIe 5.0 12VHPWR cable from the PSU or the original 1-to-4 8-pin adapter that came with the graphics card.

Will the 12+4 pin connector fit my RTX 3090 Ti alongside an RTX 4090 in the same build?

The cable supports 12+4 pin GPUs including RTX 3090 Ti and RTX 40 series cards; it is not compatible with the older 12-pin RTX 30 series connectors.
