so from your pictures it looks like to power x10 you need only 3 pci-e sockets and not 6? As on cable has one in and two out connections.
You need 6 6pin pcie, Im just using the adapters they included.
the adapters are fine, but when possible always use 6 seperate cables connected to your breakout board.
its more stable and chances for burnt cables are minimal..
i plan to use one HP 1200W PSU per miner, unfortunately they havent told us the power consumption of the 2 unknown algos yet..
