All connection are good. So, the power supply comes with 10 ports but the miner only have 6 ports, the question is does the port has to plug in in orders? ( i don't know which one to which).
I will get measure it tomorrow when i get one,
As long as those six ports in the miner are powered, you are ok.
There is no specific connection order for the cables.
And you don't need to worry about spare pci-e power cables.
Also the PSU input is 180/260V AC, so i have to use 220v right?
Yes.
