There are several things that you need to consider when choosing a computer system. However, you also need to take into consideration your power supply. Choosing a power supply that is not suitable for your system will only lead to more complications, and this is something that you want to avoid at all costs. Before you purchase your power supply, you should first make sure that you know the form factor of your computer. This includes noting whether your computer is fit for ATX power supplies or Micro ATX alternatives. You should also make sure that the power supply will fit inside your computer casing, as this is another vital factor when it comes to installation.
ATX Casings and Power Supplies
ATX cases require an ATX form factor PSU to operate at maximum efficiency, but some ATX models provide a higher amount of power and therefore are much longer than standard models. If this is the case, then you should consider purchasing a larger case to protect your unit. Another thing you should consider when purchasing your computer power supply unit is the quality of the product. A cheap power supply is much more likely to fail than if you paid a little more to get a good brand that is known for performance. Having a cheaper power supply will also put your entire computer at risk, as burnouts are very common with poorly made power packs and this could easily lead to the destruction of valuable components.
Overall Power Output
When purchasing your power supply, you should also take note of what power you’re going to need. If you operate your desktop computer on a daily basis for general duties, then a standard 350-400W power supply will be more than efficient for running your computer. Computers that use 350-400W power supplies generally have a mid-range CPU and a low end video graphics card. If you plan on upgrading your system in the near future, then it would be wise to opt for a higher end power supply, such as a 500W output model. If you intend to use your computer for intense gaming purposes, then you should look at 650W and upwards. This is especially the case if you intend to use more than one video card with your system.
