Manufacturer description

The Fasgear 600W PCIe 5.1 GPU power cable replaces the stubby 10cm adapter that ships with most RTX cards, giving you a 70cm sleeved run from your modular PSU to the 16-pin (12+4) 12VHPWR header. It terminates in three 8-pin (6+2) PCIe male plugs, so you feed the card from three separate PSU rails rather than daisy-chaining. Fasgear builds the run from 16AWG tinned copper instead of the more common 18AWG, which is what backs the 600W output rating and the claim of steadier voltage delivery under sustained load; the tinned finish is there to resist oxidation over time.

SpecPicks Verdict

SpecPicks scored Fasgear 600W PCIe 5.1 GPU Power Cable 16pin 12VHPWR Black 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.

Frequently Asked Questions

Will this cable work with my Corsair or Thermaltake power supply?

No. Fasgear lists this cable as compatible only with ASUS, EVGA, and Seasonic fully modular power supplies. PSU-side pinouts are not standardized across brands, so using it on another brand risks damage.

Which graphics cards does this 16-pin cable support?

Cards with a 12+4-pin 12VHPWR connector: the RTX 3090 Ti, the RTX 40 Series (4070 Ti, 4080, 4090), and the RTX 50 Series (5070, 5070 Ti, 5080). It does not fit the 12-pin RTX 3090 or the 8-pin RTX 4070.

Do I have to plug in all three 8-pin connectors?

Yes. Fasgear states that connecting fewer than three 8-pin (6+2) plugs to the PSU may cause system damage. Make sure you have three unoccupied PCIe ports before ordering.

How long is the cable, and will it reach in a full tower?

The sleeved run is 70cm (2.3ft), roughly seven times the length of the ~10cm adapter bundled with most cards, which gives enough slack to route behind the motherboard tray in most mid and full tower cases.

What wire gauge is used and what is the warranty?

It uses 16AWG tinned copper, a heavier gauge than the standard 18AWG, supporting up to 600W output. Fasgear lists an 18-month warranty; check the product listing for current warranty terms.
