Technical FAQs 4

What are the different types of PC power supplies?

Computer power supplies come in various form factors, each designed to fit specific PC case sizes and requirements: The ATX (Advanced Technology eXtended) power supply is the standard PSU form factor for most desktop PCs. It typically measures 150mm wide, 86mm high, and 140mm to 180mm deep, following Intel’s ATX standard.

What type of power supply do I Need?

ATX is the most common, but compact builds may require an SFX or TFX unit. EPS power supplies are designed for high-performance workstations and servers, while ATX units are used in specialized applications. A reliable PSU should include built-in safety mechanisms to protect components from power fluctuations.

What form factors should a power supply take?

The rub here is that there are three main form factors that your power supply can take: ATX and SFX / SFX-L. Interestingly, the regular ATX standard designates the width and the height of the PSU, but the length can vary. But for the SFX and SFX-L standards, the length is set.

What are the different types of power supply?

Each type offers distinct advantages, catering to different requirements, and ensuring efficient and reliable power delivery for a range of applications. Explore essential power supply form factors like ATX, SFX, and specialized types such as redundant and hot-swappable.
