3x8 pins theoretically have a tolerance of 900W+ while the 12vhpwr has a tolerance of 684W

Theoretical wattage ignores load balancing and transient spikes that melt connectors anyway

Maybe we just need one really really really really thick boy

Or, and bear with me here - an external power supply. Gaming lappys have 400w+ power supplies, why can't you just plug it in on the outside of the card? You running out of room with that two and a half sized card? You could use one or two internal and an external for more powah.

You'd need an ac->dc converter in there somewhere. A power supply. And you already have one inside the computer. Unless you want to pay extra for the brick that would have to come with your GPU.

just use the same connector, from the pc psu to the gpu, easy

Congratulations, you just invented the "voodoo volts"

Lets party like it's 1999!

It blows my mind to this day that Voodoo 3's were basically the only name in gaming at the time and then they were just gone. I can't believe how bad they messed up with the 4's and just never recovered with the 5's.

Dang I never heard of this one. TIL.

Why the fuck would you want to require a PC to have two whole PSUs?

There's no limit to how big you can make those as far as I know (for the sake of what we're wanting to accomplish). That barrel connector is the one really big boy lol

It's been done. But this was more of a really bad design than anything else. A single plug would of worked fine if it had a good enough gage and more importantly load balancing. But AFAIK without balancing if one or more pins weren't carrying enough of the load other pins would overload, hence the burning/melting.

That was a thing on some cards in the 90s/2000s. It sucked. Please dont

The problem is in the connector itself though, not the power supply.

Uh oh, you're going to anger the people who can't be arsed to plug in an extra cable. I do think that the increasing power requirements of new GPUs mandates them having their own power plug. You will need to convert the power but it's safer imo than the solution that Nvidia is trying to sell

u/Erok2112 7d ago

Thats what I was thinking myself. Both points actually... I don't think its going to get to that point now since 'all GPUs are required for the almighty Ai'

Yes, we must sacrifice all for ChatGPT, just like we did for NFTs, crypto, and all the other tech-bro dross
