Seasonic X-Series 660W Power Supply Review

Over the last couple of months we have looked at the excellent X-Series 850W and 1250W power supplies – they both earned our highest awards. Today we look at the more affordable 660W version, a modular design which has achieved 80 Plus Gold Certification. This range of power supplies has proven popular with the enthusiast audience as they are a ‘no-compromise’ design incorporating high grade Japanese capacitors and class leading standards of build quality.
