Manufacturer description
The Fasgear 16pin GPU cable is a 1ft (30cm) sleeved extension. One end plugs into your graphics card's 12+4-pin (12V-2x6) socket and the other end splits into three 8-pin PCIe connectors for your power supply's leads. It replaces the card's short 10cm stock power tail with a longer, tidier run, so you can route power around the case instead of leaving a cramped bundle hanging off the GPU. Inside, Fasgear uses 16AWG tinned copper wire instead of the 18AWG common on standard cords, and the tinned finish resists oxidation. The extension is rated for up to 600W output. Its 12V-2x6 connector is…

Frequently Asked Questions
Will this Fasgear extension cable work with an RTX 4090 or RTX 5080?
Yes. It is designed for cards with a 16-pin (12+4) power socket, including the RTX 3090 Ti, 4070 Ti, 4080, 4090, 5070, 5070 Ti and 5080, as well as RTX 4070 models that use a 16-pin connector.
Does it fit the original RTX 3090 (non-Ti)?
No. The standard RTX 3090 series uses a 12-pin connector, which this cable does not support. It also will not work with GPUs that use 8-pin power inputs, such as 8-pin RTX 4070 models.
How many power supply connectors do I need?
You need three unused 8-pin PCIe leads from your power supply, and all three must be connected. Fasgear warns that connecting fewer than three can cause system damage.
Is a 12V-2x6 cable compatible with a 12VHPWR port?
Yes. Fasgear states that the 12V-2x6 connector is backward compatible with 12VHPWR ports, so it plugs into 16-pin GPUs with either connector type.
What comes in the box and what is the warranty?
You get one 30cm (1ft) 16-pin to 3x 8-pin PCIe 5.1 sleeved extension cable and 4 transparent cable combs. Fasgear covers the cable with an 18-month warranty.
