No 12VHPWR connector connected RDNA3 GPUs?
Multiple sources present assertion that AMD volition not beryllium adding a caller PCIe Gen5 powerfulness connector to its caller Radeon GPUs.
Kyle Bennett recently revealed RDNA3 Navi 31 GPU volition enactment unannounced (at the time) DisplayPort 2.1 specifications, lone for the VESA consortium to formally announce 2.1 specs a fewer days later.
According to Kyle’s sources, AMD is not planing to adhd PCIe Gen5 powerfulness connector to caller Navi 31 notation cards, successful fact, nary committee spouse paper is now confirmed to beryllium utilizing specified connector either.
After the @NVIDIAGeForce melting drama, I person verified done aggregate sources that @Radeon Navi 31 ref cards volition NOT usage the 12VHPWR powerfulness adapter, and I could not verify immoderate AIBs utilizing 12VHPWR connected N31 either.

This quality comes conscionable arsenic NVIDIA is facing reports astir melting 16-pin powerfulness connectors connected their 450W GeForce RTX 4090 graphics cards. The institution adopted 12-pin powerfulness connector for its RTX 30 Founders Edition GPUs backmost successful 2020, lone for the caller ‘Ada’ bid to diagnostic the afloat implementation with 12+4pin and defined arsenic 12VHPWR spec and offering up to 600W of power.
As a substance of fact, Kyle’s assertion is not the lone one. It was Angstronomics who were archetypal to interruption the quality that AMD is not readying to usage the caller powerfulness connector connected their notation designs. The institution would trust connected dual 8-pin powerfulness connectors connected their Navi 3X based model:
The notation paper appears to person an updated 3-fan plan that is somewhat taller than the erstwhile generation, with a distinctive 3 reddish stripe accent connected a conception of the heatsink fins adjacent the dual 8-pin connectors.

The tract correctly mentioned 3 reddish stripes connected the notation design, which was revealed by AMD successful precocious August. However, AMD’s authoritative render did not amusement immoderate powerfulness connector:

There is besides a study from Igor’sLAB who revealed a PCB plan for the upcoming RDNA3 GPU, perchance a customized variant. That paper reportedly features triple 8-pin powerfulness connectors. With that successful mind, determination are present 3 sources with comparatively bully way grounds claiming that AMD is not utilizing 12VHPWR connector connected RDNA3 GPUs.
If these reports crook retired true, past NVIDIA volition stay the lone institution utilizing this caller high-power connector. And that’s contempt Intel and AMD launching caller desktops cards astir astatine the aforesaid time.
