EPS 6pin Cpu connector on old Be Quiet! PSU ( Dark Power Pro 650W) - Power Supplies - Linus Tech Tips

So my friend got this old power supply for cheap but we cant find a cable for the cpu at all. We need something like 6pin to 4+4 (8pin) cpu power connector, to power Ryzen system. Does anyone know if its safe to use adapters from pcie to eps for cpu power, or should i just search for the fitting
