The brand new StealthXstream 2 600 Watt power supply can get 85% efficient at typical loads. This PSU offers, stability, decent design and then good performance and top notch efficiency. With 600 Watts the PSU falls into the mid-range to lower segment of the high-end category. The product is NOT a certified SLI/Crossfire ready product, there's three year OCZ PowerSwap Warranty.

Conclusion:

During the test session the reviewers compared this power supply to similar PSUs they've tested with a similar setup, the OCZ StealthXstream 2 series is quite efficient, a recent Enermax 80+ GOLD certified PSU did show better results though. For an 600W power supply, the cabling was a bit of a concern. The cabling was too short and for graphics cards there was only one 6-pin and one 6/8-pin PEG power connector. If you have several cards you'll need converter cables. There's a need for more PCIe GFX PEG headers, especially wjith modern video cards. The overall quality was quite good, no irregularities or a-typical behavior under hefty stress was shown.
