Back of the board has doublers.
Also this confirms the Killer SLI is bad. It doesn't even have USB 3.1 gen2 , dual BIOS, or ALC1220, so for the $10 price difference to the Extreme4 it is really bad.
The VRM is at least $20 upgrade , audio is minimal (maybe $10) , USB 3.1 probably $15-20 based on add-in card pricing.
The Taichi is using Fairchild FDPC5030SG parts while the Extreme4 looks to use Sinopower SM7341EH.FAIRCHILD http://www.onsemi.com/PowerSolutions/product.do?id=FDPC5030SG

asdkj1740 , the ubiq parts might be what are used on MSI GPUs.
QN3101 high side , QN3107 low side seems to be what is on Zotac's GTX 1080 Ti amp
