ASUS Introuduce An RTX 4070-based graphics card without a power cable

ASUS unveiled the Megalodon, an RTX 4070-based graphics card that can run without a power cable, at Computex in Taipei. It was a first, and nobody was sure the Taiwanese company would be able to bring this ambitious initiative to fruition on an industrial scale at the moment.

The time has come for physical connectors to take the place of our graphics cards’ power cables. The RTX 4070 card of this kind, known as Megalodon, was initially unveiled by ASUS at Computex 2023. Since then, various GPU prototypes with a GC-HPWR connector have surfaced all around the world.

A unique feature of the Megalodon graphics card is its cableless power supply, which is accomplished via a proprietary GC-HPWR connector rather than a “classic” 12VHPWR. This port has a single connector capacity of 600W, which is sufficient to power a genuine powerhouse like the Nvidia GeForce RTX 4090, for instance.

The GC-HPWR connector is prepared for manufacturing, but not everyone will be able to use it

This would address the overheating issue that certain RTX 4090 owners encountered, in which their PC had melted because of an inappropriate 16-pin adapter. The risks may easily be eliminated by forgoing a cable, allowing overclockers of all stripes to exercise their passion without worrying about perishng in a fire.

The argument is thus made that card manufacturers will adopt GC-HPWR and produce it in big quantities. You’ll likely need to exercise patience, but it’s only a question of time. There is still a problem to be solved, and it is not the least of these advantages that this connector offers over the 12VHPWR. It can only be utilised with the right motherboard, and only ASUS appears to be commercially prepared to enter this market. We can see that the financial incentive for the assemblers is not yet strong enough when we consider that these cards will need to be more expensive than present models and that they will only be utilised to power high-end GPUs.
