The form factor determines the physical size, shape, and connector layout of a power supply, making it one of the most important considerations. The best form factor is the one that matches your computer case and motherboard—common types include ATX, SFF (Small Form Factor), and TFX. Choosing the correct form factor ensures proper installation and airflow, and prevents issues with fit or connector compatibility. For example, the New Genuine Sparkle FSP300-60THA-B 350W Power Supply is an ATX form factor suitable for standard desktops, while the HP Compaq Pro 6000 6005 6200 6300 6305 240W SFF Power Supply fits SFF cases. With various form factors available, you can select the power supply that best matches your system’s requirements.
