Efficiency & Noise Level Certifications Database

The following database includes all PSUs that we have evaluated so far.

The databases below include power supplies that have been tested with either 115 VAC (60 Hz) or 230 VAC (50 Hz) or both voltage inputs. Regardless of voltage input, we conduct some tests with 230 VAC (50 Hz) to check compatibility with the (EU) No 617/2013 regulation and the ErP Lot 6 and ErP Lot 3 directives. You can select a manufacturer/company to see its certified products, and you are also able to export the database in CSV format.
