ASUS says it is testing a method to run GPUs with no visible power cable by pushing up to 250W directly through a reinforced PCIe x16 slot.

Today’s slots top out at 75W, which is why most cards need extra 6/8-pin or 12VHPWR leads.

ASUS’s concept merges and reinforces the slot’s five 12-volt pins and feeds the slot itself via an extra 8-pin on the motherboard.

In a recent demo, ASUS showed a concept TUF GeForce RTX 5060 Ti drawing 248W entirely from the slot.

That’s potentially enough for many mid-range cards to run cable-free, though true high-end boards will still need dedicated connectors.

This is not BTF or GC-HPWR. Back-To-The-Future (BTF) just hides cables. Graphics Card High Power (GC-HPWR) adds a proprietary board-to-GPU power socket.

This concept instead enhances the PCIe slot so it alone can deliver up to 250W, with the cable moved to the motherboard.

Fewer cords is always good, but it’s very early days

Rather than hiding a separate GPU plug, the cable is routed to the motherboard, tidying up the build while keeping standard PSUs in play.

ASUS says backward compatibility is part of the pitch. Prototype cards designed for the enhanced slot would still run in regular boards, falling back to the usual external power leads if needed.

However, several hurdles must be cleared before the bold vision can become a reality.

Because this deviates from the PCIe spec, it would require matching new motherboards and GPUs, and wider industry buy-in isn’t guaranteed.

Safety and reliability will also be under the microscope.

Pushing 250W through the edge connector means thicker contacts, strong clamping pressure and robust board traces so heat doesn’t build up where it shouldn’t.

Also, don’t expect cable-free flagships. Cards that gulp well north of 300W remain out of scope for this approach.

Currently, it’s a proof-of-concept designed for cleaner builds and simpler installations in the 150–250W ‘fat middle’ of the market.

If rivals adopt it, and standards bodies endorse some form of it, future mid-range GPUs could simply snap in and work, with cases finally free of that bulky GPU cable.

Until then, this remains a promising prototype that shows where PC building might be headed.
