Specs and features StealthXStream 2 600W / 80+ Certified / ATX

So today we are peeking at the this 80+ certified 600 Watt power supply. OCZ is actually releasing several models within this specific range, these PSUs will beĀ starting at a shy 400 Watt going all the way up to 700. The 600W unit tested today starts out with four 12V rail, each capable of a 18A maximum output. You have 140W available on your 3.3 and +5V lines.

With that amount of power under the hood it's clear that the StealthXStream 2 series is catered at the value for performance end-users. The guys with a home PC that like to game on a mid-range PC. The StealthXStream 2 is chilled down with 120mm ball-bearing fan and features a standard ATX power supply form factor resulting in a compact footprint to accommodate virtually all computer towers.

Primary feature is of course the good efficiency with itsĀ  80+ certifications, converting up to a full 85% of AC to DC power at typical loads.

With 600 Watts the PSU falls into the mid-range to lower segment of the high-end category. Although not exactly Kilowatt material, it most certainly is capable enough of running a dedicated mid-range to high-end PC. The product is NOT a certified SLI/Crossfire ready product but can support up one card with its default connectors, one PCIe PEG leads will offer a 6/8-pin (DXX) connector and one 6-pin header can be spotted for graphics cards. That is more than sufficient for a single GPU GPU setup. The OCZ StealthXStream 2 power supplies come backed with a nice three year OCZ PowerSwap Warranty.
