Founded in 2002 in California, OCZ Technology Group, Inc. has as main objective to be a major competitor in the market in terms of memories RAM, now dominating the manufacture and distribution of SSD's and sources. "OCZ Technology was founded by enthusiasts, for enthusiasts, and our commitment to that end-user group has not digressed. Entering the memory market in 2002, OCZ was built around the determination to manufacture the very best high-speed memory for overclockers." The ZT series is the ideal choice for a PSU for those looking for design, performance and price. With a fully modular design, ZT series maintains its internal environment organized by eliminating the clutter of wires and improve air flow using only the cables that are accurate. The ZT is the newest series of power supplies from OCZ, whose models are fully modular cabling system and 80 Plus Bronze certification. Available in versions with 550W, 650W and 750W.

Rather than we are accustomed to a olio boxes and wires, OCZ only presents two containers In one of the boxes have all the wiring, the cables from the main board, up to molex This source has the particularity of having wires all sata cables in black In the other package, only the PSU OCZ presents us with a great design and very clean. any source painted with a glossy black, with a few letters in yellow This photo says it all. Fantastic to see a 100% modular PSU. A look professional and simply beautiful to behold! The cables are present as follows: Something we can worry about is bringing only 2 PCI-E cables, but given that it is a PSU of only 550W, it will not be the most suitable for CrossFire systems At the rear of the source have all the power scheme, as well as some certificates assigned to the series ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- - Interior and Conclusions Cooling from OCZ ZT 550W is made by a 140mm fan in all black Yate Loon Thai brand. This type of fan is most common in all the sources of high quality. As with the ZX series, the OEM source of this is the High Wall, so we can find a large PCB, in this case all black. Although the filtering stage of this source is not perfect, it is good, considering that we are talking about a PSU of about 60 €. This source gives us 4 capacitors and 2 Y on X as in most PSU's of OCZ. Tests made with CoolerMaster PSU Tester where the results are obtained and the average of those studied. 3.3V Rail - 3.135V - 3.465V aceitável 5V Rail - 4.75V – 5.25V aceitável 12V Rail - 11.4V – 12.6V aceitável Voltage +12V Rail(s) Normal: 12.0V Min: 12.16V Max: 12.02V Voltage+3.3V Rail Normal: 3.30V Min: 3.35V Max: 3.31V Voltage +5V Rail Normal: 5.00V Min: 5.05V Max: 4.95V - Eficiency 20% - 86% 50% -88% 80% - 86.3% 100% - 85% - Temperature 20% - 30º 50% - 35º 80% - 41º 100% - 49º - Noise 20% - 24db 50% - 27db 80% - 35db 100% - 41db Comparing with the PSU we tested earlier, this results in efficiency obtained a slightly better but the most impressive was the difference in temperatures was obtained. We can conclude that the fact that this source is 100% modular, helps a lot in cooling, which makes it one of PSU freshest I've ever had in my hands. The fact that the fan at 2800RPM load's reach makes it a bit noisy but only in load. Prós + Attractive design and simple 100% modular, which is certainly extremely good sources for today Extremely good performance with great efficiency values. Source pretty cool price Cons - Guard and could add another 2 PCI-E cables Load the noisy With that attach to the OCZ ZT 550W certificate r1sKas Choice Gold! Regards, Ricardo Castro @ r1sKas
