Fan Noise

Unfortunately the fan of the OCZ ProXStream is not nearly as "whisper" quiet as the package promises. Also the fan does not seem to be controlled by temperature, or it changes only so slightly that I couldn't hear nor measure it. Part of the fairly high fan noise can be attributed to the 80 mm fan which has to run faster than if OCZ had used a 120 mm fan.

Value and Conclusion

With a price of $299 the OCZ ProXStream is competitively priced compared to other 1000W power supplies, but still, 300 dollars are 300 dollars to pay.

High Price

If you are looking for an extremely powerful power supply that can power anything you throw at it, the OCZ ProXStream 1000W might be a good choice. 1000 Watts are a multiple of what even the most demanding rigs require in power. This will leave you a large headroom that improves voltage stability.
However, since no system I could think of really needs that amount of power, the big question is: Do you really need a 1 kW power supply? Most 1kW power supplies on the market are bigger than the standard, which means you have to make sure that it fits into your case. OCZ's unit is the same size like any other PSU, so it fits all cases. The cables are sleeved nicely, allowing for a clean look of your case inside.
The loud fan is a bit annoying and definitely not for a quiet rig, but if you (think you) need a 1kW PSU you are not worried about silence but want performance and overclocking.
With an efficiency of 75%, the unit is not only extremely powerful, it also helps you save energy.
