Tuniq Potency 650W Power Supply Review
 

The Tuniq Potency 650W power supply is a no nonsense unit that will get the job done on a basic computer system without wasting your money on bells and whistles. It has decent features and specifications, was able to power the test configuration without issue, and it remains cool and quiet during operation.
