guys, I am trying to connect PCIE with extender cable, after peel off the shield plastic, I realize the copper wire isn't too thick, is it normal? how do I know if the cable is not suitable to use if it's too thin? I can't take a photo as cable is too small for my phone camera to take a clear picture, please advise.

Power supply direct output cable marking: 18AWG

Extender marking: 22AWG

is it ok to use this extender cable?

avoid it is my suggestion. it will probably be fine as long as 1 entension per blade, but they will almost certainly get warm.

my experience:
20awg: running 3+ and 3- to each blade gets warm
18awg: running 3 is fine, running 2 is also slightly warm
14awg: running 1 and 1- is sufficient per blade and no warmth.

I would suggest using the thickest cables you can - it is cooler and easier of the PSU (to make wires warm means you're losing several watts between the PSU and the antminer)
