OCZ ModXStream PSU

The OCZ ModXStream Series is a new line of power supplies designed to offer consumers a combination of OCZ's legendary PSU architecture and an effective modular cable management system. Available in 780W and 900W models, the ModXStream offers power solutions to gamers on a budget, and hardware enthusiasts alike. The ModXStream was engineered to be the quietest PSU available so gamers can hear their games and not their PC. The load-controlled 120mm cooling fan helps keep the unit operating efficiently, but Benchmark Reviews knows that there is more that meets the eye with each and every power supply. Load testing for AC ripple and DC power regulation will prove if the OCZ ModXStream 780W Modular PSU OCZ780MXS is as good as it looks.

By now you should know that the power supply unit is the single most important part of any computer. Regardless of the system or purpose there is a given rule: whether it is a simple workstation with integrated components or an advanced gaming system with newest technology available, everything requires power to operate. As anyone who has suffered the failure of a low-end power supply will tell you: not all power supply units (PSU's) are created equal, and looks don't mean a thing.

As a gamer or case modder, modular cabling is a necessity when building a cool and orderly system. To optimize airflow and eliminate a cable mess, the ModXStream power supply is equipped with "EZMod" technology to allow complete customization of your power system by utilizing only the cables you require. Kept ultra-cool with a load-controlled 120mm fan, the powerful ModXStream still remains virtually silent and supremely cool even at peak loads.

Next generation platforms and high performance graphics cards are essential to modern gamers and hardware enthusiasts, just as much as the new software designed to use them. Complete with two PCI-Express cables and six serial ATA connectors, the ModXStream is built to provide sufficient output to power demanding GPU and system setups. With a sustained output of 780W over four +12V rails to provide uniform distribution of power, the ModXStream is very capable of driving today's higher end systems.

Benchmark Reviews has seen some major changes within the power supply industry over the past year. Even in such a limited purpose industry, somehow fads manage to come into existence. At one point, the number of rails a PSU offered was key to media hype. At another point, you could see everyone pushing for the highest watts in their new product. I can't forget how modular power supplies, with the assortment of cables and interfaces, also shared some time in the limelight.

The latest trend seemed to be 80-Plus efficiency, but since most PSU's are at least this efficient the label has lost meaning. And then without any warning, it was as if every company manufacturing power supply units suddenly decided that they could win the battle for industry dominance by combining all of the above features, and add a nice paint job or mirror finish for good measure. The new generation of power supplies has begun to amp up the competition for placement in your computer case. Antec’s EarthWatts series was among the first to cause a stir in the PSU industry by emphasizing efficient power delivery over the multi-rail hype over two years ago. But now 80% or better efficiency is very common.

The OCZ ModXStream provides Universal Input and Active PFC (Power Factor Correction) to effectively regulate input voltage across worldwide power grids and maintain an economical, yet stable supply of power. What this means to you is that the days of switching between 110/220V and 50/60Hz cycles are well behind you. Even if something should fail, all OCZ ModXStream power supplies come backed with an industry-leading three year OCZ PowerSwap Warranty for the ultimate peace of mind.

About the company:ocz_logo_200px.png OCZ

Entering the memory market in August 2000, OCZ Technology was built around the determination to manufacture the best high speed DDR and RDRAM. OCZ was founded by enthusiasts, for enthusiasts, and our commitment to the end-user has not digressed. OCZ Technology has been an innovator in many areas. We were the first manufacturer to make Dual Channel optimized memory available to the public, which originally took advantage of nVidia's Twinbank or Dual DDR architecture, found in their nForce chipset. We have now taken that technology and tailored it for the Canterwood, and Granite Bay chipset's. OCZ developed and was the first to implement ULN technology, which has been a critical element in our manufacturing process for some time. We at OCZ diligently work to improve communication with CPU and motherboard chipset manufacturers prior to the release of their products. Only in this manner can we fine-tune our memory's SPD settings, ensuring a synergistic relationship between the memory module, memory controller, and microprocessor. In today's rapidly evolving semiconductor industry, such communication is not simply research, but a necessary component of our manufacturing process.
