SMPS (Switched mode power supply) or PSU (Power Supply Unit) is the very important part of your computer. All parts are running through SMPS. It is important for PC performance and stability. As per your PC components power requirement you should go with good brand SMPS. I personally prefer to use 80 plus brooze certified SMPS if you are planning to create great performance PC for gaming or video editing.
New generation CPU and motherboard does not require much power. So You need to check GPU power requirent and based on that get your SMPS.
For Gamers and video editor I suggest 650Watt. For normal PC users and moderate gamers can go with 450watt SMPS.
Here are some list of SMPS:
