[ OCZ ZX Series Features ]

The OCZ ZX series boasts a number of features, such as a fully modular cable management system, ball-bearing 14cm fan, Japanese made electrolytic capacitors, solid state capacitors, overvoltage, overcurrent and short-circuit protection. The OCZ ZX series utilizes a single +12VDC rail and what this means is if you have a graphics card capable of sucking down more than 18A for example on a single rail, then the system will crash (BSOD) or something to that effect. The 70A (850w), 83A (1000w) and insane 104A (1250w) single rail designs of the OCZ ZX series makes them much harder for SLI/Crossfire graphics cards to max out, and with this arrangement it cannot be done without significantly more hardware added to the system. This kind of arrangement could also produce more stable and better overclocking results. The OCZ ZX power supplies all utilize a 14cm dual-ball bearing fan made by Yate Loon. The seven blade fan operates at 2800 RPM and is said to move 140 CFM of air while making 48.5dBA of noise. This is a DC fan with a 12v/0.70A rating with the model name D14BH-12. Finally, the last key feature is the 80 PLUS Gold certification, which means under 20% load the power supply will have an efficiency level of 88%, while this will increase to 92% under 50% load, and finally 88% at 100% load. This means that the ZT power supplies waste 12% or less electricity due to heat when operating at room temperature. However OCZ also claims that the ZX series will deliver full power continuously 24 hours a day, 7 days a week when operating at temperatures as high as 50 degrees Celsius. Of course we are not sure what this temperature, which is just over two times greater than room temperature, does to the unit’s operating efficiency. The efficiency of a computer power supply is the amount of energy it supplies, divided by how much energy is input. The remaining energy is converted into heat. For example if a 750w power supply only had an efficiency rating of 60% under full load, it would draw 1250w from the wall, 500w of which would be lost as heat. However, if we had a 750w unit with an 80% rating, 930w would be drawn from the wall and just 180w would be lost as heat. Finally, the 80 PLUS Gold certification, which calls for a maximum load efficiency of 91%, means that a 750w will draw 820w from the wall which means it will lose just 70w as heat. So the greater the efficiency the more you save on your power bill and the “greener” you will become.

Posted on: 06/30/2011 11:30 AM Great looking quality power supplies. If they made a 650w version or thereabouts I would snap it up in a heart beat! Nice work on the review and great images. Also thanks for opening it up.

doc	Posted on: 06/30/2011 12:45 PM im liking this fully modular is a must for all high end power supplies. also its great that you can do away with the 4 pin atx connector.

Stuff like memory, hard drives and even motherboards are so cheap now yet high quality power supplies are like SSD's.
