Probably dated but I am finding the JOYJOM cables are most likely the same as MODDIY. They have identical 90 degree and 180 degree cables as MODDIY and even the labels on them are the same part numbers with slightly different revision numbers.

​

Like between:

JOYJOM: https://www.amazon.com/dp/B0C2H2BN47/ref=emc_b_5_i?th=1

and

MODDIY: https://www.moddiy.com/products/ATX-3.0-PCIe-5.0-600W-12VHPWR-16-Pin-180-Degree-Angled-Adapter.html

Seem like the same product.
