Introduction and Features
The OCZ GameXstream power supply can deliver up to 56A on the combined +12V outputs with very good regulation and efficiency. It features ATX12V v2.2 support, active PFC, a blue LED fan, sleeved cables and a 3-year warranty.
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.

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 Â±0.05%)
- Extech 380803 Power Analyzer (Accuracy Â±0.5% of full scale)
V-650F 60 MHz dual trace oscilloscope (Accuracy Â±3%) Hitachi
- Powerstat Variable Autotransformer, 1.4 KVA, 0-140 VAC
- FLUKE 52-II digital thermometer (Accuracy Â±0.3ÂºC/0.5ÂºF)
- Extech Model 407736 digital sound level meter (Accuracy Â±1.5 dB)
- AccuLab V1-10kg digital balance (Accuracy Â±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.
