How to buy a computer power supply?


Many cases actually come with an atx power supply pre-installed. If your computer is going to be used primarily for low-end applications, such as office work and web surfing, this power supply will typically suffice; however, high end gaming PCs will require power supplies with higher power output. If you’re using a high end graphics card, you should pick at least a 500W power supply; multiple graphics card configurations could require 750W or even 1000W. There are also modular power supplies, which allow you to only attach the connectors your PC uses.
