Choosing the right power supply unit (PSU) is crucial for building a reliable and efficient computer. In 2026, white PSUs have gained popularity for their sleek aesthetic and compatibility with modern case designs.

Understanding PSU Form Factors
Power supply units come in various form factors, with the most common being ATX, SFX, and TFX. Each form factor has specific dimensions that determine compatibility with different cases. In 2026, ATX remains the standard for most desktop PCs, but smaller cases increasingly support SFX PSUs.
