Ensure the cable you use has PCI-E connectors included with your power source and connect it to the red PCI-E headers on your power supply. This setup allows any extension designed for standard PCI-E 8 pins or PCI-E 6+2 pins to fit in the CPU connector on your motherboard. Note that the headers on the power supply housing aren't universal—cables from different brands or models won't work unless the manufacturer explicitly states compatibility. Some makers, like Corsair, offer similar connectors (Type 3 or Type 4), so check their specifications. Seasonic and others have standardized cable packs; however, a Rosewill supply from Hipower/Sirtec may not match another Rosewill model's cables, making cross-brand compatibility uncertain.
