Final Thoughts and Conclusions

Seasonic’s new PRIME 750W Titanium power supply excelled in every way during our testing. We opened this review by stating that the Prime 750W Titanium is the best power supply we have tested to date. That’s a pretty lofty claim so let’s look at what “best” means to us. Here is a brief checklist of the various areas we expect a PSU to perform and deliver. In each case the PRIME 750W Titanium met or exceeded our expectations.

•    Tight voltage/load regulation (=0.5% is outstanding)
•    Excellent AC ripple and noise suppression – check
•    High efficiency – it doesn’t get any better than 80 Plus Titanium
•    Selectable fanless fan control mode – check
•    Very quiet, high quality FDB fan – check
•    Fully or semi-modular cable design – check
•    Flat ribbon-style and/or sleeved cables – check
•    High-quality components and excellent build quality – check
•    At least a 5-year warranty (10-Years is out of the park)

Overall the electrical performance was spectacular. What really stands out is the super-tight voltage regulation (thanks to Seasonic’s Micro Tolerance Load Regulation), 80 Plus Titanium efficiency and excellent AC ripple and noise suppression. We really like the ability to choose whether or not to run in fanless mode or not (I personally like to have the fan spinning at all times to keep a little air moving). The PRIME Titanium Series also features fully modular, flat ribbon-style cables and a large, quiet cooling fan with a Fluid Dynamic Bearing.

In addition to stellar performance, the PRIME 750W Titanium offers a full complement of safety and protection features. And Seasonic even tricked out the enclosure a little by adding a chrome-plated fan grill.
