When you build a desktop computer or plan to upgrade the existing hardware in your machine, it is important to choose the right power supply. The power supply supplies power to all components of your desktop computer, so if you choose a bad model or one with too few Watts (W), it may have consequences.
If you choose a power supply from Cooler Master, Corsair, EVGA, Inter-Tech or Seasonic, you are sure to get a quality product and a good performance. However, you still need to choose the right amount of Watt (W).
There is not one power supply that fits all systems. You will need to calculate how much power the different parts of the machine use and then select a PSU that fits. There are several tools online for this and if you are still in doubt, feel free to contact our support. If you plan to run SLI or Crossfire, you should expect to need a powerful power supply. If you also value cable management and the visual expression on your setup, you should consider a full or semi modular version.
The choice of a full modular or semi modular PSU has advantages other than just visual. With a semi modular power supply, you can remove all cables except those required for operation. On a full modular, you can remove and replace all the cables, even those that are necessary for the power supply to work. Many choose a modular PSU as it provides a better airflow and provides more options to customize your computer.
All power supplies have an 80 Plus rating that shows how effective they are. The standard is called 80 Plus, as even the least effective power supplies must be over 80% effective at a 50% workload.
