OCZ StealthXStream 2 600 W Power Supply Review

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.

  1. I cant get over the price of this, that is very cheap. especially for such a well constructed unit/

  2. OCZ are onto another winner I see, the original unit was very good value as well, especially at the price. nice to see they improved this one and didnt mess it up.

  3. The addition of an 8 pin PCiE makes huge sense, it was what has been putting a friend of mine off buying one for a while, even though the price was right. glad to see they have maintained the good regulation throughout.

  4. This is an absolutely brilliant release from OCZ and while i adored the review of the corsair AW1200 on kitguru recently, that is as much as I would pay for a graphics card, or more! this is priced just right and will handle even a GTX480. love it, and stellar review again.

  5. Well color me impressed with this PSU, first review ive seen of it online, didnt know they even had a new range. Excellent product by the looks of it.

  6. what a great product at an even better price. I used to have an OCZ PSU, never had any problems with it either, would recommend them or corsair.

  7. This is really very hard to fault at such an incredible retail price. you dont get this kind of quality normally at such a low price. just shows you though how many people chase wattage figures when you dont really need it. 600-700w is more than enough for anyone today, unless they are into high end SLI or CFX

  8. I love kitgurus PSU reviews. so informative for both experienced and novice users. conclusion alone had me sold, shall hunt this out for my brother for his system soon.

  9. Very very solid product from OCZ and as everyone else has said, it is hard to fault for that price point. normally you end up with a fung wung no name easter make at £50.

  10. My PSU died last night! this looks to be a good shortlist option, as well as the slightly more expensive Thermaltake 750w reviewed here a few weeks ago.

    What do you guys think, 600W enough for futureproofing? might be a bit tight.

  11. Is that price right? that seems very good pricing from OCZ, they aren’t normally so cheap.

  12. Nice looking PSU too, isnt it? those enermax ones lately are like blinged out and look awful

  13. I had a b ad experience with a gamesstream unit years ago and I swear I will never touch OCZ again, it caught fire and starting smoking. I am sure this is good but once you get burned like that, you never go back.

  14. Great review, looks very competitively priced and performance is more than enough for anything today, apart from dual GFX configurations

  15. Great review, time for an order for my new system with a GTX460 in it 🙂

  16. Great review of this, I only found a few reviews online and both say its great/ OCZ have my money 🙂

  17. SO many wonderful products reviewed on this site, great the ‘crap filter’ for rubbish products means other sites get the tosh 🙂

  18. Found this site from google, cant imagine ive never seen it before, bookmarked!
