Computer Power Supply Units (PSUs)

A computer power supply unit (PSU) converts mains AC into low-voltage regulated DC power for the internal components of a PC. At ComX Computers South Africa, you can find ATX, micro-ATX and mini-ITX power supplies designed to support gaming systems, office desktops and professional workstations.

Types of Computer Power Supplies

  • Standard ATX PSUs: The most common size, compatible with full tower and mid tower ATX cases.
  • Micro-ATX PSUs: Slightly smaller units suited for compact micro-ATX builds.
  • Mini-ITX PSUs: Ultra-compact supplies for mini-PCs, HTPCs and space-saving systems.
  • Modular PSUs: Cables can be attached only when needed for cleaner builds and improved airflow.
  • Semi-modular PSUs: A balance between affordability and cable management flexibility.
  • Non-modular PSUs: Fixed cables, offering reliable budget-friendly performance.

Key Features to Consider

  • Wattage: Choose from entry-level 400W units for office PCs to 1000W+ models for high-end gaming rigs.
  • Efficiency ratings: Look for 80 Plus Bronze, Silver, Gold or Platinum certification for energy savings and reliability.
  • Cooling: Large, quiet fans or 0dB semi-passive cooling ensure silent performance.
  • Connectors: Support for GPUs, SSDs, HDDs and modern motherboards with 24-pin, 8-pin and PCIe connectors.
  • Safety features: Built-in surge protection, over-voltage and thermal safeguards for component security.

Who Needs These PSUs?

Gamers need high-wattage, efficient power supplies to support graphics cards and cooling systems. Office and home users benefit from reliable mid-range PSUs for everyday workloads. Professionals building workstations should select modular or semi-modular units for tidy cable management and stable performance.  

Shop Power Supplies in South Africa

ComX Computers stocks a wide variety of ATX, micro-ATX and mini-ITX power supplies suitable for all types of PC builds. Whether you are upgrading an existing desktop or assembling a custom gaming rig, you’ll find high-quality PSUs that deliver reliable performance and excellent value.
