OCZ ProXStream 1000W Power Supply

Introduction:

    Just a few years ago, it was all the rage to have a 500W or even a 600W power supply to keep dual graphics cards happy with power. Well, now it's all about Quad Core CPU's and GPU's, and these processors require more power to properly function. OCZ is stepping up to the challenge by offering the Multi-GPU Ready ProXStream 1000 Watt power supply. Designed for die-hard gamers and hi-end computer systems, the ProXStream 1000W provides stable, clean power to quad GPU systems and system components.

About the Company:

    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.

Open Box

    The OCZ box comes wrapped in plastic to protect against tampering when placed on store shelves. The box is silver and blue with a plain looking power supply on the front. The normal layout applies for the rest of the box, with the features on the back and specs on the side. The retail box is larger than the standard box these power supplies normally come in, which had me wondering how much larger the PSU might be.

A Closer Look:

OCZ 1000W & 850W

Side by Side

1000W of goodness

    Upon opening the box, I was surprised to see how small this 1000W power supply actually was. It is no bigger than a typical 500W power supply or the 850W I just reviewed. This is a good thing, as it doesn't require any extra computer case real estate. Unfortunately, the OCZ ProXStream 1000W is not modular, but that's not a big deal since most of the connections would be used anyway in either a quad setup or a server setup.

80mm Fan

3/4 side

Inside Vent

    The chassis of the ProXStream has a nickel chrome finish, which looks nice over the standard black. The sides have some vent holes but they are covered by black plastic from the inside, so these vents are not very effective. The back, with the wire harness coming from it, is one large vented area with rectangular holes, while the front just has an opening for the 80mm exhaust fan and power connection. The overall look is very industrial.

    The heart of the ProXStream 1000W consists of four 12 volt rails, each handling 20 amps with a minimum amount of noise. Built-in protection from a short circuit will trip the power supply with a 0.01ohm change in resistance. Over voltage protection trips the power supply if the voltage limits reach 4.0V on the 3.3V rail, 6.2V on the 5V rail, or 14.6V on the 12V rails. If by chance the power supply shuts down due to a power issue, simply unplug the power for a few seconds to reset the power supply.
