Choosing a good Power supply can at times be a difficult task. Today's PCs require additional power to supply extra HDDs or the power hungry VGA SLI and Crossfire setups.

OCZ Technology, one of the most respected and best known memory manufacturers, recently entered the Power Supply arena. We have previously reviewed on this site, their PowerStream 600W which proved to be a real winner, and now have the opportunity to try the "GameXStream". This power supply is mainly aimed at enthusiasts who are looking for a PSU capable of powering their SLI/Crossfire enabled systems. Recently, the GameXStream PSU line was updated with the addition of the 1010W model, to support the demand for Nvidia's 8800GTX SLI setup with four PCI-E connectors.
