Introduction and Features
Excellent performance and high efficiency at a great price!
Seasonic began introducing their new PRIME Series power supplies last year and we have reviewed several of the flagship PRIME units and found them to be among the best power supplies we have tested to date. The PRIME Series currently includes fourteen different models that range from 650W up to 1200W and offer 80 Plus Titanium, Platinum or Gold certification for high efficiency.
Sea Sonic Electronics Co., Ltd has been designing and building PC power supplies since 1981 and not only do they market power supplies under their own Seasonic name but they are the OEM for many other big name brands.
In this review we will be taking a detailed look at the Seasonic PRIME 1000W Platinum PSU. This unit comes with all modular cables and is certified to comply with the 80 Plus Platinum criteria for high efficiency. The power supply is designed to deliver very tight voltage regulation on the three primary rails (+3.3V, +5V and +12V) and provides superior AC ripple and noise suppression. Add in a super-quiet 135mm cooling fan with a Fluid Dynamic Bearing, top-quality components and a 12-year warranty, and you have the makings for yet another outstanding power supply.
