The S12II Series SS-520GB 520W 80 Plus Bronze Power Supply from Sea Sonic Electronics is designed for basic desktop computers that require low noise and simple installation. It has a 80 Plus Bronze rating, ensuring up to 87% efficiency and power savings. The 120mm fluid dynamic bearing (FDB) fan utilizes Smart & Silent Fan Control for a balance between silence and cooling, and is built to last longer than traditional sleeve bearing fans. In addition, the unit uses high-quality 105°C Japanese aluminum electrolytic capacitors, ensuring stable operation under extreme conditions and extended life. Included are all the cables you would need for a standard system build; however, this power supply unit is not modular so you'll have to organize and hide any unused cables.
