And the motherboard does require a 24 pin power supply.
But it would go in the same case as the one referenced in the article.
I just looked at the Gigabyte board (post #7) in addition to the 24 pin power connection it also has a 8 pin connection...as my Asus 880 board...but I am running ok with a 4 pin power connector so didn’t have to buy a new power supply.
