Introduction and Features
Still one of the best PSUs money can buy!
It’s been almost two years since we first looked at Seasonic’s top of the line PRIME 750W Titanium power supply. Since then Seasonic has tweaked the design, increased the warranty to 12-years, and added “Ultra” to the name. So what else has changed? Is the PRIME Ultra Titanium still one of the best power supplies money can buy?
Sea Sonic Electronics Co., Ltd has been designing and building PC power supplies since 1981 and they are one of the most highly respected manufacturers in the world. Not only do they market power supplies under their own Seasonic name but they are the OEM for numerous other big-name brands.
Seasonic’s PRIME Ultra lineup was introduced last year with the Titanium Ultra Series, which currently includes four models: 1000W, 850W, 750W, and 650W. Additional PRIME models with both Platinum and Gold efficiency certifications as well as a fanless model are also available.
All of the PRIME Ultra Titanium Series PSUs come with all modular cables and are certified to comply with the 80 Plus Titanium efficiency criteria; the highest available. The power supplies are designed to deliver extremely tight voltage regulation on the three primary rails (+3.3V, +5V and +12V) and they provide superior AC ripple and noise suppression. Add in an upgraded super-quiet 135mm cooling fan with a Fluid Dynamic Bearing and a 12-year warranty, and you have the formula for an outstanding PC power supply.
