Extension Kit for RTX 40 GPUs

This Monoprice 179 cable kit adds a 12VHPWR PCIe 5.0 extension plus 24-pin ATX and dual 8-pin CPU extensions. The 16AWG UL 1571 tinned copper wires are rated for 600 W and finished in white sleeving. It targets builders who want cleaner cable routing on compatible NVIDIA RTX 40 graphics cards.

Suited for RTX 4070 4080 4090 owners

The 12+4 pin connector works with RTX 4070, 4080 and 4090 models including Ti variants. It does not support RTX 3000 series cards or AMD GPUs, so buyers with those GPUs should look elsewhere. The kit also includes ATX and CPU extensions that fit any PSU using standard cables.

Check PSU connectors and clearance

Verify your power supply provides native 12VHPWR or 8-pin PCIe ports for the GPU extension. Confirm the 30 cm length reaches from your PSU to the graphics card without strain. Ensure both 12VHPWR plugs seat fully to deliver the full 600 W rating safely.

Questions about this item

Which PSU connectors must I already have for the 24-pin ATX, dual 8-pin CPU and 12VHPWR extensions to attach?

Your power supply needs a native 24-pin ATX output, two 8-pin (4+4) CPU outputs and one 12VHPWR (12+4 pin) output so each extension can plug in directly.

Will the 12VHPWR extension deliver 600 W to an RTX 3090 Ti Founders Edition card?

The 12VHPWR cable is rated for 600 W, but the kit is listed as compatible only with RTX 4000 series and 3090 Ti FE; other 3000-series cards use a different connector.

How can I verify the 12VHPWR link is seated well enough to carry the full 600 W after installation?

Push both 12+4 pin ends until they click flush with the GPU and PSU ports; a fully inserted connector prevents power leakage and enables the rated 600 W delivery.
