Desktop Power Supplies

Choosing the right desktop power supply

Power supplies for desktops are responsible for converting mains voltage and delivering stable power to the processor, graphics card, drives, and other components. The correct power supply ensures safety and reliability for your entire computer system.

Main types – ATX, SFX, and more

The most common desktop power supply is the ATX model, designed for standard computer cases. For smaller form factors, SFX power supplies are used, while EPS models are suited for servers and workstations. Pico power supplies are ideal for ultra-compact mini-ITX builds. Always check compatibility with your case and motherboard before making a choice.

What to consider when buying?

• Wattage – Match the power output to your hardware's needs. An underpowered unit may cause instability or shutdowns.
• Build quality and protections – Good power supplies feature overvoltage and thermal protection for added safety.
• Energy efficiency – Higher efficiency means less energy loss and lower electricity bills.
