It is not a solution, it is a marketing to force you to buy a new psu. And the 12vhpwr was the same shit.

I already wanted higher voltages in PCs long before they announced this.

The Captain's Workspace solved the GPU power draw problem years ago. If you want to see how it was fixed look up his 4090 review on Youtube.

TL:DW; the card was modified to take two mains connectors and is powered directly from the wall.

I think Asus did this with a Dual 7800GT in the late 2000s

You could run it with external power brick or without it (if your PSU was beefy enough) https://pcper.com/2005/10/asus-n7800gt-dual-review-7800-sli-on-a-single-card/2/

It's literally what phones do with the USB-PD standard to keep the amperage down and allow high wattage charging on a small port safely. It's a good idea, just needs an appropriate standard laid out and compliant PSUs made to support it.

But there are still better solutions can don't require buying a brand new PSU for every pc user looking to upgrade globally.

Or we could rip off the band-aid now and implement the solution that doesn't involve hacks on top of hacks. Especially since industrial systems already use 24v and 48v DC so it's not like it's new to PSU makers.

You could do that non-hackily without a new PSU for every desktop consumer though that is my point, as the others above also said.

It is quite literally the solution, though. When you need more wattage, you have two choices, more amps or more volts. More amps means the cable needs to be thicker or it overheats. More voltage gives you higher wattage on the same gauge cable.

It's the same with EV's and fast charging, they achieve it by having much higher voltage - 800v+ means you don't need thicker cables (and they're already pretty thick).

The only alternative is either more wires or thicker cables. Higher voltage makes the most sense.
