I’m a bit inexperienced here, I just got a new used gpu and it’s a full-size and it has like 12 holes for the pin connector, I only have one 6 pin, will this one work? Or do I need an adapter?
you can buy adapters if the psu is adequate. like sata power to 6 pin or something. but tbh buy a new psu it will pay off in the end and the efficiency on a new one will likely be better anyways.
Which GPU are you actually having ?
