you can but don't do it.

Most PCIe cables are AWG16 (better ones are AWG14) and they're rated at 13 amps. 13A * 12V = 156W. That's the maximum power that's safe to draw using those cables. If you use 1 cable for 2 cards you're asking for trouble, those cables might catch fire.

not like this.

PEIe cables with 8Pin was 3x12v, so 13*12*3=450w.

Are you sure AWG16 can run with 13A?

I check some data , AWG16 max is about 6A.

so one PEIe with 8pin can only drive 6*12*3=216w.

so this is why 1080ti must 8+6pin or 8+8pin

You're right and wrong and I was wrong

AWG16 max current is 3,7A as per https://www.powerstream.com/Wire_Size.htm

My first post was from my head and you're right I didn't take the 3 power leads into consideration. So the correct math is 3,7*3*12=133W per cable.
