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.
