As seen in PCWizKid's video review, from packaging to installation the OCZ ZX 850 Watt Power Supply is exceptional.  However the real test was that during full load testing where the single 12v rail stays within a +/-1% deviation and delivers high efficiency at 89% which demonstrated that it delivers a consistent output.  With an easy to use modular design , plenty of connector support this PSU shows quality and craftsmanship (wth 5yrs warranty to back it up).  If price is not much of an issue this PSU has quality and style to keep any PC Enthusiast happy for years. The system we tested was fully packed and overclocked to maximize the power requirements on the OCZ ZX 850W, which didn't even break a sweat! PCWizKid gives the OCZ ZX 850 a "Recommended" Award.
