Introduction:::...

When NVIDIA first announced their GeForce 6800 specs back in April, earthquake monitoring stations worldwide apparently simultaneously reported a strange low frequency tremor which was later attributed to two things, PC users trembling in fear and the collective pricking up of several hundred thousand pairs of ears belonging to hardware manufacturers looking for a new line of revenue.

Though now reduced to a more reasonable 350watts, NVIDIA's initial requirements for a 480watt power supply had companies the world over scrambling to add suitably muscled units to their product range and cash in on what they thought would be a mass upgrade frenzy to get in step.

Of course it didn't happen, but that's not to say it never will, and if you're on the verge of replacing your power supply you'd certainly be well advised to be looking for something larger rather than smaller. I mean, you're PC will be quite happy running your power supply at 50% of its potential output, but you try running at 150% of its potential output and you'll soon realise your mistake.

Today I want to look at a power supply from a company more readily known for their high performance, high value memory. OCZ, despite a checkered past, have moved on with a new management team, work ethos and, I believe, ownership, and are now recognised as a top brand for both enthusiasts and quality-conscious users alike, and their new line of power supplies seems to be causing quite a stir with their looks, innovation and quality.

The unit I have on the bench today packs over half a kilowatt of power into its sleek enclosure, but there's power and there's clean, efficient power.

The OCZ PowerStream power supply family offers the quietest, most versatile and adaptable PSU available today. The PowerStream PSU family comes in 420W, 470W and 520W configurations; they are the ideal solution to your computer power needs.

With its universal ConnectAll™ connector, the PowerStream power supply offers all-in-one connectivity. (ATX, BTX, Serial ATA, P4 and EPS12V) Every OCZ power supply offers PowerShield™ power leads with enhanced EMI-control technology to reduce RF interference, stabilize input current and filter out “ripple noise”.

Each OCZ PowerStream family member includes the PowerFlex™ feature for fine-tuning the three adjustable power rails. An LED sits below each of the three adjustment dials; a green light indicates voltage is within ±5% of optimal, a yellow light indicates undervoltage, and red indicates overvoltage.

The OCZ PowerStream PSU box has an eye-catching nickel-plated chrome finish and boasts green exhaust fan LED’s and colorfully wrapped wires.
