So, I got the Onda board up and running with my normal 4x GTX 1080 Ti setup.

I'm tempted to add four more cards to it. Putting a rig in the Thermaltake Core X9 didn't impress me. So I'm thinking of taking it's 4 cards and adding them to the Onda. Could also take the Corsair AX1200i power supply. Then I'd could use two of those PSU to power the combined rig.
What do you all think?
Nice you have the new version without the blocking mobo power cable. I'd say just do it, since your cards are watercooled and temps won't be an issue.
I've got a rig of 3x hybrids and 3x 1080ti sc2 (soon to be 4).

Those 3700rpm fans pushing through the radiators man, the cards are never above 37 degrees even at the hottest time of the day of 32 degrees. I had to lower core OC, it was boosting too high due to the low temps lol.
