ASUS Demoes GeForce RTX 4070 with No External Power Connector

During the Computex 2023 show, ASUS had some interesting designs to showcase. Specifically, ASUS has made a GeForce RTX 4070 GPU concept without an external power connector. With NVIDIA's reference 16-pin power connector melting due to an insufficient connection, ASUS has decided to experiment by removing the connector from its GPU and placing the power source as an extra bus connector on the motherboard. Called GeForce RTX 4070 Megalodon, ASUS has made a custom power connector that goes hand-in-hand with the ASUS TUF Gaming Z790 BTF motherboard that supports this connector, and the PSU cables go on the backside of the board.

Similarly to NVIDIA's 16-pin 12VHPWR connector, this custom design is also rated for up to 600 Watts of power delivery. This results in a design that facilities the user error of not correctly pushing the 16-pin connector and causing melting. For now, the connector is referred to as GC_HPWR, but there will be an official name at launch as the company plans mass production of this concept. You can see the design of the RTX 4070 Megalodon alongside the accompanying ASUS TUF Gaming Z790 BTF motherboard.

Chrispy_In fairness I missed that this was a reversed board like the one MSI is showing.
It's a solution that just makes cases wider though (since now we need even more space behind the motherboard tray for cable bend radius AND plug+socket z-height.

I'd be less irrated by this if all of the major case and motherboard vendors had collaborated on an ATX+ reversed-board standard or something, but it's looking like Asus boards only work in Asus cases, and MSI boards only work in MSI cases.

I don't even like the idea, but I'm okay with that. What I'm not okay with is a bunch of conflicting proprietary formats.
It would have been nice if they used 90 degree angled connectors. then you don't need so much space.

Yeah, with new GPUs getting unbelievably huge, it's almost insane that they're demoing concept designs that force the case to get even bigger than they already are. ATX is already horrendously dated and wasteful with space. It needs improving, not making worse!

Perhaps if you want a giant empty tower that contains mostly void space and RGBLED nonsense as some sort of e-peen, then great. The rest of us want a PC to do it's job and not take up half the room...

Outback BronzeCool! Nice clean build there with fairly powerful GPU. Impressed.

Asus will prob charge like a wounded bull though : (
I agree but damn get rid of the proprietary bit and make it a general ATX spec, Please.

Because one manufacturer is just a death sentence, we are as enthusiasts a niche.

When it hits the BOM price, it's getting taken out of the BOM, since there's options and obviously OEM are cost sensitive.

As is would enough buy it to keep it as a thing viable?!.

Ps it looks x16 compatible IF it doesn't touch raised coolers IE, the power inlet fingers look to be raised such that there connection on the motherboard would have to stick out twice as far as the motherboard, but obviously they have no other power inlet , have they just covered optional power inlets with an RTX badge bit pointless otherwise..

If this is how things were, Standardized then I would like it.
Proprietary, stick it.

AGP Pro did this already over 20 years ago.
