The Seasonic FOCUS SGX Series 650W 80 Plus Gold Modular SFX-L Power Supply is an efficient and durable unit designed to deliver consistent power for small form factor systems. Thanks to its modular cables, you can plug in the ones needed and store the rest to reduce cable clutter and improve airflow. As for cooling, it's equipped with a 120mm fan that supports Fanless Mode, which keeps the fan off until there's sufficient load on the system for silent operation. All the standard cables you'll need in a build are included such as the motherboard, CPU, PCIe, SATA, and 4-pin Molex/peripheral cables.
