Maybe they should start to amp up the voltage. Since those cards already have dedicated power connectors why not have 24 or even 48 volt lines?

- sschueller 4y agoI am not aware of an ATX power supply nor any proposed standard for ATX that will provide more than 12V.
- LordHeini 4y agoMe neither and i wonder why. There really should be no reason. I had to throw away many perfectly good power supplies when upgrading the graphics cards because they had not enough pins. So i would count out economic reasons. Many 3d Printers started to convert to 24v recently because you have thin cables and overburdened plugs for high powered heaters and stepper motors. That caused no issue either it is amazing what modern voltage regulators can do.
- scohesc 4y agoI believe it was for energy saving purposes. The reasons were for better and more efficient power supplies, not having multiple voltage outputs with multiple current ratings, etc. I'd be happy with a separate tier of PSU that has the standard 12v rails, but also includes a rail with 36 or 48 volts for dedicated GPUs. The less amperage running down those slim wires, the better...
- jnsaff2 4y ago> Maybe they should start to amp up the voltage. You mean "amp down with up the voltage"? But this is my reaction too. Running 50 Amps even these short distances is just silly. I would think about maybe saying that the card is 48V and here are the dongles that let you put four of the regular power supplies in series.
- eternityforest 4y agoI wonder if they could develop GPUs meant to run in series directly from higher voltage? Shunt regs could prevent imbalanced current long enough for software to rebalance the cores?
