I'm not sure if this is the best place to post, but does anyone know if these bad boys are sold anywhere else?

I have this PSU and it only came with 2 of these cables that are needed to connect to my PCI risers. I figured out from trial-and-error that I can use 1 cable for 2 GPUs but not more than that or ethOS becomes unstable. So I'm currently maxed out with 4 GPUs and the other 2 are sitting in their boxes

Thanks in advance!
