OCZ has announced its new Z-series 850W and 1000W power supplies in both standard and modular configurations. These units are not only powerful, but efficient as well; the units are certified 80 PLUS Gold which means they are over 90% efficient at typical loads. Each model offers a single +12V rail rated at 83A (Z1000/Z1000M) and 71A (Z850/850M) respectively. These are industrial strength power supplies designed to offer continuous output at the rated levels at 50°C and come with active PFC (.99PFC). The units are cooled using a 135mm thermally controlled fan that matches fan speed to the units temperature and load to help keep noise levels under control. Each unit is backed by OCZ's 5-year PowerSwap warranty and are currently shipping to resellers. They carry suggested retail prices of $299.99 (Z1000M), $289.99 (Z1000), $239.99 (Z850M), and $219.99 (Z850).
