"Branded the Z-Series and available in 850w and 1000w models, this is THE FIRST PSU to pass through the OC3D labs with a shiny gold 80PLUS sticker on its packaging. It's hard to miss the stupendously powerful single +12v rail rated at 83A! OCZ has pulled out all stops and gone for a gunmetal coloured brushed aluminium. During the standard load tests (1-4) on the unit it managed to hold at least 90% efficiency at all times, sometimes going as high as 93% showing that this unit is certainly worthy of its title. Particularly impressive was the Z1000M's ability to hold a 1268W load at 50°C continuous. This potentially shows that the Z1000M is more than likely designed to be a 1100-1200W PSU under the surface with a 1000W sticker slapped on the top, making for a good value purchase."

"The OCZ Z1000M is the first available in retail, 80+GOLD certified power supply in Japan. When compared to Seasonic S12, OCZ modular version of 1000W model is a much more powerful and efficient solution. The measured efficiency rates stood at 88.23% (20% loading), 90.93% (50%) and 89.20% (100%) – all easily met the minimum levels set by 80+GOLD standard. The unit’s cooling is efficient and the fan adjusts dynamically to loading – remaining quiet even at a full loading – we measured only 38.2dB compared to 37.5dB at idle mode. We recommend this unit to anyone, who uses its system under heavy load frequently."

"This power-saving model, OCZ Z1000M, is 80+GOLD certified. Having the option to plug in as many as 12 SATA cables as well as 6 of eight-pin (6+2) PCI Express connectors means that this power supply has enough plugs to satisfy even the most extreme power users. The Z1000M features a modular cable system which optimizes airflow. On top of that are very small dimensions (160mm length) of this 1000W modular model. It will fit into any case and leaves plenty of room, so it will be simply to plug in any additional cables after installation of this unit into your case as never before."

"This module modular power supply, OCZ Z1000M, is very impressive. Starting with the sleek package, we’ve got a feeling as we’ve received a very unique product. The OCZ Z1000M looks and feels very high-end. The 13.5cm double ball-bearing thermally-controlled GLOBE FAN is renowned for powerful yet silent cooling. Active PFC of Z1000M output design is based on two Japanese top-quality Nippon Chemi-Con capacitors. We measured the highest power efficiency rates among all tested models: 88.23% at 20% load factor, 90.93% at 50% and 89.20% at 100%. Overall, OCZ paid great attention to detail – starting with decent package of the Z-Series, solid housing, top quality components and excellent power efficiency and stability – Editor’s Choice."

"OCZZ1000M is a hefty supply of 1,000 watts with a Gold-80 PLUS efficiency. But the goodies do not stop here. Not only does the independent test from Network Power experts confirm that the Z1000M has an efficiency above 90 percent, it can also continuously cope with a load exceeding 1200 watts. If you need an advanced power supply for powerful systems with multiple graphics requirements, the OCZ Z Series 1000w is certainly worth considering."
