PSU Tier List: F (2025) Do Not Recommend

Tier F lists power supplies that should not be recommended. Key reasons include:

• Missing or non-functional safety protections (risking catastrophic failure).
• Units that are unreliable or unsafe for their intended use.
• Very poor electrical performance that fails to meet ATX specs under their rated conditions.
• Severe quality-control issues that cause widespread premature failures.
• Absence of active power factor correction (APFC), a feature often required by regulations and typically one of the last things removed when costs are cut, missing APFC is commonly signaled by a manual input-voltage switch (often red) on full-range units; some 230V-only models may also lack APFC.

This is the data scheme for each line:
