The Seasonic PRIME Titanium PSU (650W, 750W, 850W) Review: Mythical Performance
 

Seasonic made it easy for us to summarize the entirety of these units’ performance in just one word: mythical. The very high efficiency that easily broke the 80Plus Titanium certification requirements with 230V AC input was a small surprise at first, but surprise turned to shock when we began testing the units inside our hotbox. Not only the high ambient temperatures hardly shook the efficiency of the units, the power quality and voltage regulation figures were just incredible.

Before testing these three units, we would not believe that such performance would be possible with a consumer-grade PC PSU.
