Manufacturer description

The Fasgear 16-pin (12+4) GPU power cable is a single-cable 12VHPWR to 12VHPWR run built for full-modular power supplies that already have a native 12VHPWR port. At 70cm, it replaces the stubby 10cm factory lead so you can route power behind the motherboard tray instead of coiling slack in front of the card. Fasgear builds it to the PCIe 5.1 spec with 16AWG tinned copper conductors rather than the more common 18AWG, which the brand credits for steadier voltage delivery and support for up to 600W of output. The 12V-2x6 plug uses alloy copper contacts with tinned plating to resist oxidation…

SpecPicks Verdict

SpecPicks scored Fasgear 16pin GPU Power Cable using a rating × review-volume × price-fit model applied to published specs and reviews across the accessories category. Fasgear's accessories lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for accessories of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.

Frequently Asked Questions

Will this work with my RTX 5090?

Yes. Fasgear lists the RTX 5090, 5080, 5070 Ti and 5070 among supported cards, along with the 4090, 4080, 4070 Ti and 3090 Ti. Your GPU needs a 12+4-pin female connector.

Do I need a specific power supply for this cable?

Yes, two conditions. Your PSU must be full modular, and it must have a native 12VHPWR output port. Semi-modular and non-modular units are not supported, since there is no port to plug into.

Does it work with the original 12-pin RTX 3090?

No. Fasgear states this cable does not fit 12-pin RTX 3090 cards or 8-pin GPUs such as the 8-pin RTX 4070. Only 12+4-pin cards including the 3090 Ti and the RTX 40 and 50 series.

How much power can it actually deliver?

Up to 600W. Fasgear uses 16AWG tinned copper wire rather than the standard 18AWG, plus a 12V-2x6 plug with alloy copper tinned contacts, which it credits for steadier voltage under load.

Is 70cm long enough for a full-tower cable route?

70cm (2.3ft) covers the behind-the-tray route in most mid and full towers, versus the roughly 10cm factory adapter. Four transparent acrylic combs are included to keep the sleeved run tidy.
