OCZ EliteXStream 800W Review

» Discuss this article (3)


To properly test the OCZ EliteXStream 800 watt power supply, I will be using a digital multimeter to gather readings of the different rails of the power supplies. I will be doing this under two conditions. The first will be idle testing, measured after the computer has been started up and sitting for about a half hour doing nothing. The second condition will be measured while the computer is performing different tasks back-to-back, such as an OCCT 30 minute stress test, as well as 3DMark06. Our current testing methodology revolves around testing each independent rail with a multimeter to verify the lack of droop and to ensure that the voltage is maintained within specifications. In the near future OverclockersClub will follow a more formal load testing methodology to provide a more in-depth analysis of the power supply. Keep checking back for that change.

Testing Setup:

  • Processor: Intel E6600 @ 3400MHz
  • Motherboard: Gigabyte GA-P35-DQ6
  • Memory: Mushkin PC2-6400 (4GB)
  • Video Card: Sapphire HD3850
  • Hard Drive: Western Digital 320GB 16MB cache SATA
  • Optical Drive(s): Lite-on DVD-RW
  • Case: Cooler Master Cosmos 1000
  • Heatsink: Thermalright Ultra 120 Extreme
  • O/S: Windows Vista Ultimate

Comparison Power Supplies:





  • Power Supply: Cooler Master Real Power Pro 850W
  • Power Supply: Ultra Power Partner 325W
  • Power Supply: OCZ 700W GameXStream












    The OCZ EliteXStream power supply did exactly what I needed it to do, power the system that I had put it in. Not only did it power the system that I put it in, it also was able to deliver the power on the rails very close to what the ratings are.
