What are the key features to look for when choosing a PSU brand?

Always choose a PSU with 80 PLUS® (Platinum or Titanium) certification. The higher the category, the less energy you’ll lose as heat, the lower your bills, and the more reliable your system will be. A bunch of benefits at once.  

Another important point is to check the modularity of the power supply. A fully modular unit allows you to only connect the cables you need, which reduces clutter and improves cooling. For instance, Seasonic FOCUS models and higher in the prime line offer such a feature. 

Check that the PSU format (ATX, SFX) matches the parameters of your case (especially important for compact (SFF) systems) and set of protections such as OVP, OCP, and others..
