Introduction and Features

OCZ designed the SLI-Ready GameXstream 700W power supply specifically for PC enthusiasts, Power Users, and Gamers!  OCZ's new GameXstream power supplies are built by Fortron-Source (FSP) and incorporate high-quality components that deliver stable output voltages with high efficiency and minimal noise.  The power supply features quad +12V outputs, active PFC, and a single 120mm cooling fan with blue LEDs for added lighting effects.  All of the sleeved cables are hard-wired.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />


 



 


OCZ GameXstream 700W PSU Key Features:


 



  • 700 watt maximum power output

  • ATX12V v2.2 and EPS12V support

  • Quad +12V outputs (up to 56A/680W)

  • Dual PCI-e 6-pin connectors (nVidia SLI Ready)

  • Quiet 120mm cooling fan with blue LED lights

  • Industrial grade components

  • High efficiency (80% to 83% typical load)

  • Black mesh sleeved cables

  • Active PFC with Universal AC line input

  • 3-Year warranty 

In addition to the GameXstream power supply the colorfully printed box includes a power cord, mounting screws, and a printed User's Manual. 


 



 


The OCZ GameXstream 700W power supply was evaluated on both features and performance.  A full range of equipment was used to test the power supply under controlled load conditions.  In addition to measuring the power going in and coming out I looked at voltage regulation, electrical noise (AC ripple), sound level, efficiency and cost.  Here is a list of the equipment used during testing.


 



 



  • FLUKE 87-III True RMS digital multimeter (Accuracy ±0.05%)

  • Extech 380803 Power Analyzer (Accuracy ±0.5% of full scale)

  • <?xml:namespace prefix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" />Hitachi V-650F 60 MHz dual trace oscilloscope (Accuracy ±3%)

  • Powerstat Variable Autotransformer, 1.4 KVA, 0-140 VAC

  • FLUKE  52-II digital thermometer (Accuracy ±0.3ºC/0.5ºF)

  • Extech Model 407736 digital sound level meter (Accuracy ±1.5 dB)

  • AccuLab V1-10kg digital balance (Accuracy ±1g)

  • Homemade PSU load tester — selectable loads (up to 470W)

  • (2) CSI3710A Programmable DC load (up to 150W each)

  • (2) CSI3711A Programmable DC load (up to 300W each)

Establishing a controlled load is critical to testing and evaluating a PC power supply.  In addition to my own home-made load tester, I'm now using four programmable DC loads for greater flexibility and accuracy.  This new combination can place up 1,400 watt load on the unit being tested.
