Final Thoughts and Conclusions
Like all it’s X-Series predecessors, the new Seasonic Platinum 660W power supply incorporates significant advances in PC power supply design that result in excellent performance, high efficiency and the ability to operate in silent-fanless mode at lower power levels. Add to that a 7-year warranty, a good assortment of all modular cables, tight voltage regulation, clean DC outputs and you have one very good power supply! However, as you might expect, a premium Platinum efficiency certified PSU is going to be relatively expensive.
The Seasonic Platinum 660W power supply is currently selling for $149.99 USD (Newegg.com, December 2012).
