Provisions for 8-pin PCIe Power Connectors Spotted on Palit GeForce RTX 4080 SUPER PCB
Palit has kind of gone against the 12VHPWR grain with its GeForce RTX 4080 Super GamingPro OC graphics card—PC SIG's 16-pin power connector is the default standard for the NVIDIA GeForce RTX 40 series, but an outbreak of technical snafus has caused many to question the format's future. A new 12V-2x6 connection standard is touted as 12VHPWR's natural successor, but PC parts manufacturers continue to produce products that utilize the latter. HXL discovered a MaxSun custom GeForce RTX 4070 SUPER design that sported two completely bog standard 8-pin PCIe power connectors (in lieu of 12VHPWR), but a follow up report indicates that the Chinese board partner has scrubbed the offending item from its web presences.
Jisakuhibi Japan's review of the Palit GeForce RTX 4080 Super GamingPro OC model included close-up shots of the card's PCB—the publication's social media account noted an intriguing yet empty section: "(Palit's) board seems to be able to natively set the auxiliary power supply to PCIe 8-pin x 2 instead of 12VHPWR." The unoccupied area sits just south-east of the standard 12VHPWR connector—the provisional positioning of pin holes suggests that Palit's PCB could be designed for a separate professional graphics card solution. The company is unlikely to divulge its original intent with the placement of older auxiliary power connectors—ultimately 12VHPWR is the way forward.

These cards aren't all that large by themselves considering how powerful they are. This card in particular would be great with a custom waterblock from the factory.
But I guess they got road blocked by Nvidia.
the heatsink is not meant to support that as it covers that area, makes it impossible.
The reasoning is simple: because I can.
The upper is 6x12V, and 2 GND,
the lower is 4 GND plus 4 pins (sense0 sense1 pwr_ok and gpu_present) all routed to the 4 pins of the 16 pin
Considering the PCB is long enough to place the headers on the far end, the redesigning of couple of cooler fins, is least of an issue, if at all. This looks, just as MarsM4N said, being prohibited by NVidia.
That only obstructs the ariflow. Bad idea. although 12V HPWR will have a much smaller footprint and it might just work, but obviously was dropped or not finished on time to hit production with the cutouts needed on the heatsink side as it raised the cost too much. So they don't make provisions to keep the old connector or fight the unfairness of imposing a new standard, none of that because this has a completely different layout with all 6 12Vs put on one connector and all 6 grounds on the other.
