OCC has published a new review on the Tuniq Potency 550W

The 80 PLUS certification requires the Tuniq Potency to run at greater than or equal to 80% efficiency at 20%, 50%, and 100% of rated power output. While the specification has been met at 20% and 50%, the power supply failed to hit the 80% mark at 100% load for both 110VAC and 240VAC input. The power supply did, however, meet the ATX12V minimum required efficiency, and I have therefore given the power supply an overall pass in this section.
