The PSU Tier List cog integrates SPL’s (Small Platform Labs) official PSU Tier List directly into your Discord server, allowing members to look up and compare power supply units without leaving Discord.
Data is fetched from the official SPL API and cached locally. It is automatically refreshed every 6 hours to keep results accurate while being considerate of their API.
