Power supply units (PSUs) are often neglected when building a computer system. The power supply distributes the power to all the individual components within the PC, without it your PC would not run. The quality of components and technologies used to manufacture PSUs varies greatly. It is important to pick the best power supply your budget allows since a high quality PSU will provide a stable, more reliable system that will also produce less noise and heat. The higher quality power supplies will also operate more efficiently reducing your electricity bill and helping the environment. Whilst it may be temping to pick a cheaper PSU when building a PC to reduce the overall cost, it's very important to remember that a high quality PSU is essential for demanding systems such as gaming PCs and workstations where continuous power delivery is essential.

So, power up your PC with a good quality power supply unit, it will provide a more stable experience, will be less noisy, will not overheat and will also be more efficient - reducing your electricity bills.
