PC Power Supplies

PC power supplies, also called PSUs (Power Supply Units), are crucial components within desktop computers. They are responsible for converting electrical energy from an external source (typically from a wall outlet) into the appropriate voltages and currents needed to power the internal components of a computer. A high-grade PSU is important for confirming stable and reliable operation of a PC.

Key Functions of PC Power Supplies

  • Voltage Conversion: PC power supplies convert the high-voltage AC current from the outlet into the low-voltage direct current (DC) required by the computer's components. Common output voltages include +3.3V, +5V, and +12V.
  • Regulation: PSUs regulate the output voltage to ensure that it remains within acceptable tolerances. Voltage fluctuations can damage components, so regulation is critical for stable operation.
  • Efficiency: Efficiency is a measure of how well a PSU converts incoming AC power into usable DC power. Higher efficiency power supplies waste less energy as heat, reducing energy consumption and heat output.
  • Modular vs. Non-Modular: Some PSUs are modular, enabling users to connect only the cables they need. Non-modular PSUs have fixed cables. Modular designs provide cleaner and more customisable cable management.
  • Wattage and Capacity: The wattage rating of a PSU indicates its capacity to deliver power. A higher wattage PSU can support more power-hungry components like high-end graphics cards and multiple drives.

Types of PC Power Supplies

  • ATX Power Supplies: The ATX (Advanced Technology Extended) form is the most typical type of PSU for desktop computers. These power supplies are standardised and fit most PC cases.
  • SFX Power Supplies: SFX (Small Form Factor) PSUs are compact units designed for more minor PC cases, such as Mini-ITX systems. They offer lower wattage but can still power high-performance components.
  • ATX12V and EPS12V Power Supplies: These PSUs are designed for specific applications. ATX12V is for standard desktops, while EPS12V is for workstations and servers. They may have additional connectors for specialised components.
  • 80 PLUS Certification: 80 PLUS is a certification program that measures PSU efficiency. PSUs can receive certifications like 80 PLUS Bronze, Silver, Gold, Platinum, or Titanium, indicating higher efficiency levels.

Considerations When Choosing a PSU

  • Wattage: Determine the power requirements of your components to choose an appropriately sized PSU. Over-specifying wattage can save energy, while under-specifying can lead to instability.
  • Efficiency: Higher efficiency PSUs are more energy-efficient, which can lead to lower electricity bills and lessened heat generation.
  • Connectors: Ensure the PSU has the necessary connectors for your components, including the correct number of PCIe connectors for graphics cards.
  • Modularity: Consider whether you want a modular or non-modular PSU based on your cable management preferences.
  • Brand and Reliability: Choose reputable PSU manufacturers recognised for supplying reliable and high-grade units. A reliable PSU is essential to prevent power-related issues that can damage your PC.
