OCZ's StealthXstream 600W power unit withstood all the abuse we could throw at it while maintaining stable voltage levels within plus or minus 5 percent of nominal values and less than 2.5 percent fluctuation. This is especially impressive given that our dual-platform test "system" has twice the number of power-hungry components of a typical gaming rig.
Cooling was quiet enough that we didn't notice any noise from the power supply itself, and OCZ rates the unit's efficiency at 80 percent under "typical" loads.
A three-year warranty and moderately-low $85 Web price makes the StealthXstream a good value for a broad range of needs.
Pros:
- High stability under strenuous and highly-dynamic loads
- Typical-load efficiency rating of 80%
- Automatic switching for 110V and 220V source power
- Quiet enough to remain unheard below the noise of other system fans
- Three-Year exchange warranty
- Moderately-low $85 price
Cons:
- Not 80-Plus certified
- Two PCI Express Power connectors supply only two mid-power graphics cards or one high-end gaming card
The Verdict: OCZ's StealthXtream 600W power unit delivers enough high-quality amperage to power the majority of high-end systems, but at a midrange price.
