The OCZ StealthXStream 2 600W PSU from OCZ has impressed us, particularly as this is firmly marketed as a budget, value for money unit. Our testing showed that efficiency figures remain high throughout the range with it remaining over 85% efficiency until it reached about 85-90% load. OCZ in reality could have set this up for 80 Plus Bronze approval instead of the bog standard 80 Plus rating they have shipped it with. The unit is stronger than the original design with improved +12 V rectifiers and we liked to see the inclusion of a 8 pin PCIe power connector for modern day graphics card solutions.
The supply remained relatively silent until the upper end of the power delivery and throughout testing it remained unintrusive and reliable, a combination we always like to report. Aesthetically it is also sure to appeal to a wide audience as there are no multicoloured fans or gaudy LED lights incorporated.
Technically the unit is solid throughout all aspects of performance. The ripple results are excellent and the unit falls well within rated specifications, it also managed to maintain strong voltage stability throughout the range. The fact we could easily get another 100w from it without issue means OCZ have been playing it safe throughout the development cycle, meaning that even under reasonable gaming load this will be delivering a high consistency of power.
If we told you this unit only costs £56 inc vat would you be impressed? I know I was.
KitGuru says: This is one hell of a budget oriented PSU which will power the majority of gaming systems on the market.
