Sounds like they need to move to either ZIF connectors or 48V power; this kind of power over high pin counts isn't really practical.
There's a reason electrical codes don't usually let you use parallel conductors below about 4AWG/60A per conductor.
Definitly feels like we need to increase the voltage. Stepdown transformers are extremely efficient, and could be card side.
So now your GPU is going to have a separate power cable from the wall? Or are we going to have GPUs with a PC attached?
not sure what you mean.
The power supply would just provide an additional voltage, they currently provide 3.3V, 5V and 12V, they could also provide 48v too.
I'm joking. If we're going to add new power cables and a PSU to the card itself, it feels like the rest of the PC becomes an accessory to the GPU.
If you have a $3k GPU, definitely feels that way!
But it was yellow this time… It should have worked!
Do you know, because I don't, if 5090 with 3 8-pin connections would be 100% stable?
No, because it's a 600W card and 8-pin are only rated for 150W each.
Even with 4x 8-pin it's not 100%, because those can also melt.
With 4x 8-Pin you'd have max. 131.25W/150W (11A/12.5A) (depending on if the 75W over the PCIe slot is monitored) over one wire, which, while not in spec, is within reasonable expectations. Not to mention, that this would require exactly 2 of the 3 wires/plugs in each cable to malfunction, as with less malfunctioning, the power would be more distributed. And with more malfunctioning, the card would stop working. With 12VHBRN, of the 6 pins available, 5 are free to malfunction as they please. Which ends in 525W (43.75A) through one wire. Which are 100°C at 20A, and melt not far from that.
So, 99% safe if you buy from QUIHUIJUIHUJONGQUI, and, 100% safe for more reputable brands/materials.
Theoretically yes...
