"In this review we had a look at Seasonic’s latest top series, the PRIME Titanium 650W, 750W and 850W PSUs. They are not the most powerful models on the market designed for quad-GPU beats, but they are the technologically best units that Seasonic is currently offering to consumers.

.
.
Seasonic made it easy for us to summarize the entirety of these units’ performance in just one word: mythical.
.
.
.
Before testing these three units, we would not believe that such performance would be possible with a consumer-grade PC PSU."
