ISO 8-pin to 8-pin PCI-e power cable (straight 8 or 6+2 wld be fine) for CoolerMaster PSU. Anyone have a place to find a good-quality, trustworthy one? Wld be greatly appreciated!
Unless someone can give me pro advice ( @nathanletwory 
?) about using another cable not specifically made for CoolerMaster. I just got a Zotac RTX 3060 OC Twin Vent as my 2nd GPU, and couldn’t find anywhere online with specific match.
@Alan_Farkas would advice for shops in Finland work? 
To be honest, I’m not that much of a hardware guy. Most of my machines are frankensteined together.
I suppose a cable that has thick enough wires to bear the load should do.
In any case ensure your current PSU will be able to provide the power two GPUs and rest of your machine draw.
Thanks for the reply. Haha, I’ll let you know if I end up needing to order from Finland!
Apparently from what I’ve come to understand, PSU’s can’t nec use generic cables, or you’re liable to have problems. But this is brand new info to me…
Maybe, let everyone else know which country you do want to order from…
You mean my lame and embarrassing American exceptionalism doesn’t fly here? 
I’m hoping to order from within the U.S., if possible. Thanks for the suggestion @jeremy5!
