Seasonic introduced a new 12V-2x6 modular PSU cable model late last year—at the time, interested parties were also invited to Beta test early examples. Finalized versions have been introduced, via a freshly uploaded YouTube video (see below) and a dedicated product page. The "H++" connector standard—part of a new ATX 3.1 specification—is expected to replace the troubled "H+" 12VHWPR design. The PC hardware community has engaged in long-running debates about the development and rollout of a danger/peril-free alternative. PCI-SIG drafted the 12V-2x6 design last summer.
Seasonic's introductory section stated: "with the arrival of the new ATX 3 / PCIe 5.0 specifications, some graphic cards will now be powered by the new 12V-2x6 connector. Offering up to 600 W of power, the Seasonic native 12V-2x6 cable has been crafted with high quality materials, such as high current terminal connectors and 16 AWG wires to ensure the highest performance and safety in usage." The new cables are compatible with Seasonic's current ATX 3.0 power supply unit range—including "PRIME TX, PRIME PX, VERTEX GX, PX, GX White and Sakura, FOCUS GX and GX White" models. Owners of older Seasonic ATX 2.0 PSUs are best served with an optional 2x8-pin to 12V-2x6 adapter cable—although 650 W rated and single PCIe connector-equipped units are not supported at all. Two native cable models, and a non-native variant are advertised in the manufacturer's video.
Seasonic's video description states: "with the RTX 40-series GPUs leading the way of the newest generation of high-performing graphics cards, Seasonic stays ahead of their increasing power requirements by producing versatile power cables with H++ connectors that enable safe and easy connectivity."
Check out their native 12V-2x6 600 W graphics card cables.

They can guarantee a power supply up to 12 years but the warranty on this cable is 2 years. Not even Seasonic trusts the 12V-2x6 cable to solve the inherent issue of the 12VHPWR power connector.
Let's hope for the deserved end.
Given how tall most 40 series cards are that extra 35mm margin for bend would be impractical for most PC cases with side panel on and 90Degree connector has its own set of issues.
Again,
only 1% of the PC cases had the actual room for oversized GPU height+ so-called 35mm clearance + space to bend the cables
They've changed the spring contacts in the plug. But I don't think anyone wants to admit it because that would be acknowledging the ones used in the 12VHPWR plugs weren't up to the job.
Just for the record... there's no such thing as a "12V-2x6 cable".
Even in their video where they show the improvements, you can see that those improvements are done on the PSU and GPU side. The cable is the same.
That said, pre-bent 90° cables and the color blue are always a welcome addition to the market. :D
Anyone able to find these yet?
