12VHPWR cable for Seasonic GX-850 Gold

I have some early revision of mentioned PSU, without dedicated 12VHPWR cable.
So far I`ve used Zotac adapter (for my 5070 Ti) but recently swapped to new dual chamber case and this adapter now is visible and ugly ;)
Looking for dedicated Seasonic cable but it is nowhere available in my country :(

Is there any option to find any compatible replacement? Maybe Seasonic did PSU for other brands and looking under other brand will be helpful?
