Welcome to the brand new PSU Tier List! Worked on, by @Stefan Payne, @LukeSavenije, and myself. This is a complete overhaul.
We'd recommend that if you have a gaming system, to not have a unit below Tier B.
All information below is opinion based on fact. Units may be bumped down due to the following: missing protections, group regulation, bad electrical performance and catching fire.
List is subject to change at any time, due to change in sources available.
