Dual 8 pin card from breakout board?

[choff5507]

Quick question. Is it possible to power a dual 8pin 1080TI from a breakout board? Will running 2x6pin to 6+2 pin cables to the card be sufficient???


Also, If Im using a server PSU along with a an ATX power supply do I need that dual PSU connector cable? Or do I simply start the ATX PSU and then start the server PSU?

I know that the risers for the respective cards need to be powered off the same PSU as the cards.


Could someone please let me know if this will work and what I need to do?

No use 2x connector from the breakout board if you have 2x connector on the GPU it's better this way for power load-balancing, especially if you are going to run them @ high TDP.

screw risers... they make double spaced 9* pcie x16 boards now so you can just plug them in directly. idk maybe im crazy but I would rather buy a few extra boards and have 8 each then have 21 gpus on one board and try and trouble shoot that shitshow

Im planning on running 2 cables to each card. I didn't understand your response. I guess Im asking if it's an issue to power a dual 8pin 1080TI card with two direct cables from 2 ports on the breakout board?
