Hardware Secrets "We loved this power supply. Why? Because it has exactly the same design of two other good high-end power supplies, but costs a lot less. For the average user this is a terrific buy. This unit not only costs less than competing 600 W products, but you will be also bringing home a 720 W power supply! In fact OCZ could easily have labeled this product as a 700 W power supply and keep claiming 80% efficiency. We think this is a terrific product for the average user, being a power supply with one of the best cost/benefit ratios around."

OverClock Intelligence Agency "On the front of performance, this power supply is, without question, solid and reliable. Though this PSU is not ?SLi Certified? or ?Crossfire Certified,? I?m confident I could throw another card in there with no drawback whatsoever. The fan on this power supply is very quiet. I have never experienced a power supply that had such a full volume of air exiting the back of the unit."

Legion Hardware "The OCZ XStream power supply series as we see, really caters for almost everyone. From those building quality mid-range gaming computers, to those chasing the most extreme overclocks with insane hardware configurations, and of course everyone in between. Those building a gaming system comprising of a high-end Core 2 Duo/Extreme processor with a single GeForce 8800 series graphics card, need not spend more than $100 US. The StealthXStream 600w are more than powerful enough to run this kind of configuration."

SysOpt "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. A three-year warranty and moderately-low price makes the StealthXstream a good value for a broad range of needs."

Ultimate OC "After stressing the PSU on a full run of Prime95 and graphic instances the 12v rail only changed between 0.09v but stayed above 12v the whole time. The rails smoothing circuits made sure the voltage changes weren't erratic so it was safe. Its been stressed over a period of 12 hours on an overclocked system and hasn't flinched. The cooling of the PSU is superb, it moved a healthy amount of air with next to no noise. Seeing as its 80% efficient, it produces less heat, so less RPM of the fan is needed."

Fudzilla "StealthXStream is a strong, reliable and cheap PSU, and all OCZ brand lovers will instantly fall in love with it. We have no complaints for this OCZ product, low price is a strong argument for recommendations. We recommend this PSU to anyone who needs quality but not pricey power."

3dGameMan "This is clearly a budget power supply that's intended for affordable builds. This is certainly not a bad thing since many people are looking for a quality, well priced power supply. What's important is it provides clean, efficient power. It has excellent bang for the buck."

IT-Review "OCZ's products always showed incredible hunger towards performance perfection. Another round of applause for OCZ it is, hats off. Excellent PSU for a decent amount of money."

HardwareOverclock (Austria) "The production of this PSU is extremely good. Both from a design point of view but also on the technical side, overall it makes a very professional impression. When it comes to the features, the StealthXstream is also up to date with overvoltage/overcurrent/short-circuit protection ( OVP. SCP, UVP, OPP and PFC ). Last but not least the price of the StealthXstream is very decent as well."

Hardware Canucks "We can do nothing but applaud OCZ since they proved a great price does not equal lackluster performance by delivering power supply which performs as well as its more-expensive competitors. When it comes to the build quality and overall performance of the StealthXstream there is hardly anywhere the it fails to impress. OCZ should also receive a pat on the back for supplying cables that are of a good-length and are fully sleeved. Indeed, the StealthXstream 600W looks, feels and performs like a much more expensive power supply. Finally, OCZ?s Powerswap Warranty and excellent customer support put it head and shoulders above many of its competitors."

Xtreme Computing "The OCZ Stealth X Stream 600W PSU is a great PSU. I feel it could easily power a PC much more powerful than the one I tested it on today. The fan is very quiet I cannot hear it at all above my fans, and my fans are not loud at all as I am using my media PC to test this PSU today. It?s also a very reasonable price so anyone looking for a good mid range PSU should consider buying it."

TechZine (Netherlands) ?With the overclockers on mind, OCZ produces and launches high quality products on the market. The StealthXstream has four 12V rails, OCZ made sure that this PSU has enough power to run energy consuming systems. This beast brings enough power to the table to run SLI systems and also has enough room for some good overclocking. Overall this is a very nice product at a good price point which is why it deserves our TechZine Must Have Award."

Gamezoom (Germany) ?We tested the StealthXstream 600W for three weeks and all the rails worked without any problems. Further more this power supply is one of the most quiet units we have tested in this range.
Even with an 8800Ultra and a powerful CPU we did not manage to push the StealthXstream to the limit, the reserves are more than enough to run an SLI or CrossFire system. Silent users have to take a look at the new OCZ StealthXstream. For a fair price you will receive a stable and powerful PSU."

OC3D "The StealthXStream really has fulfilled most of my expectations and indeed, in some cases exceeded them by a comfortable margin. The unit is sold as a simple and 'unpretentious' power supply, capable of running demanding gaming computers with high reliability, efficiency and silence. tThe StealthXStream is efficient, handles load well, and is very quiet. Its size and available connectivity options makes it suitable for a massive range of cases and enclosures while delivering the same high performance. Furthermore, the StealthXStream, being an OCZ product, comes with the usual 3 year full warranty. Something all users certainly will appreciate."

Ultimate PC "Amazing value for money, great looks, PSU is basically in-audible, rails are as solid as a rock and the rails are sleeved. I mean...really what else can you ask for in a power supply?! As you can see above i found no negatives with this power unit at all."

Tweakup (Denmark) "Looking at these results, its actually quite surprising how stable this unit is, it didn´t drop below 12V at all! The other rails were also all stable. Not only performance matters, OCZ promised to deliver a quiet PSU and they certainly did. So as mentioned, the OCZ StealthXstream surprised us with even better performance than expected, great build quality and a good noise level this is why it pushes our Tweak´O meter to 90 points."

Anandtech: Holiday Buyers' Guide "The OCZ StealthXStream 600W almost qualifies as a high-end model, since it provides almost everything a high-end system would require. The price, particularly with the rebate, is what keeps it in the midrange category. You get two 6-pin PEG connectors suitable for even a relatively potent 8800 GT SLI or 3870 CF setup. It also offers a high efficiency rating and remains quiet during use."

Overclockers Club "The high efficiency of this power supply will help lower your electricity bills and the use of active power factor correction is welcome. If you are in the market for a power supply in the 600W range, then this one comes highly recommended. The OCZ Stealth X Stream 600W is a great mid-range power supply, that I would recommend for all but the top end SLI and Crossfire configurations. The unit showed excellent DC voltage regulation, even at 95% of its specified maximum load. The unit ran relatively cool and quiet, but this is to be expected with high efficiency. All in all, a well built mid-range unit that provides stable power, at a reasonable price."

Dragon Steel Mods "I choose this PSU for two main reasons, quality and efficiency, since I know and trust OCZ products it was one of my first choices, but since the system would be running 24/7 at full load I was also looking for a way to possibly save a little money. So I choose this particular power supply because of the known quality, the fact that it is 'green' and also because it was relatively inexpensive compared to the others that were available at time of purchase. With the OCZ 600watt StealthXStream Power Supply we've got a nice combination of low price, quality, efficiency and stability that is hard to beat."
