I recently took a look at a Foxconn motherboard that I used for a recent system build, I also needed a reliable power supply for it as well and choose an OCZ 600Watt StealthXStream PSU. 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.
I've had this power supply installed for almost two months now running 24 hours per day, 7 days a week at almost 100% load all the time and have not had one problem. Even at 100% load in conditions that are not the greatest, this power supply has remained stable and quiet working to keep the system up and running.

A Better Look at Things
:
In OCZ style the packaging is done stylish yet exciting, there's lots of information and pictures all over the box so you'll know exactly what's inside and what you're getting.
As expected the PSU is packed very well, all wrapped in bubble wrap for protection during transit. In addition to the PSU we have the main power cable, user manual and mounting screws if needed.
The OCZ StealthXStream has lots of ventilation holes to keep I running nice and cool, the 120mm fan on the bottom is made to be quiet yet move a lot of air around to keep things cool.
Of course on one side is the identification and specifications label. If we hop on over to Johnny Gurus website and look up the UL# E243823 we find this information:
Modstream and Powerstream models built by Topower.
GameXstream built by FSP. Evostream built by 3Y.
It doesn't mention the StealthXStream but it's that same UL number.
And of course we have a few connections, more than enough for most basic even higher end systems to run off of.

Installation, Testing and Comparison
This system was a major upgrade from the previous single core AMD3500+ CCTV security system.
When installed and running the system consists of:
Foxconn 975X7AB-8EKRS2H Motherboard
Intel C2D E4500 w/GlacialTech 5750 Silent Cooler
4xHDD (3x400GB – 1x500GB)
DVD/RW
MSI Nvidia 6200 Vid Card with Zalman VGA Cooler
GeoVision 16 channel 480FPS CCTV Capture card
3×120 mm fans
Vizo Propeller 2 System Cooler
OCZ 600Watt StealthXStream Power Supply
During the time running this system I checked it often with my trusty multimeter, I know it's not the greatest way to test power supplies, but considering this system was under full load 24/7 for almost two months now I think that counts as 'real world' testing and if it was going to fail it would have by now, or any fluctuations would have been seen during this time on the power rails. The average user will not be running their PSU at almost 100% load 24 hours per day 7 days a week recording/capturing/storing video from 16 cameras, most users will hardly ever see full load on their systems even with hardcore gaming. The system as I configured it runs between 80% and 90% load all the time, depending on what the capture card is doing, even those figures are something that most users won't do with a dual core system normally or even gaming.
So I stuck my multimeter in there and got these results:
IDLE:
12v- 12.29v
5v – 4.98v-4.99v
LOAD:
12v- 12.25v-12.27v
5v – 4.99v
Under load you can see the 12v rail fluctuated a little bit, but that was only for the first couple minutes of powering the system on and getting everything running, after that time the 12v rail stabilized at 12.25v and stayed there for the majority of the time, but it did jump to 12.26v every so often, for the most part though it was stable at the 12.25v. The fluctuations in voltage coincided with the load on the system, so that's normal.
While I was building the system I also ran Orthos Stress Prime to achieve load as well for several hours, I got the same results for the voltages.
The one small problem that I ran into was the 5 Molex connections, the system that I built required more than that so I had to use a couple Molex splitters to accomplish what I needed to do.
Summary:
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.
My use for this power supply might not be typical of most systems out there so the lack of Molex connections for me might not affect most other people out there as it did me.
DragonSteelMods gives the OCZ 600W StealthXStream Power Supply a 4.5 out of 5 score and our Recommended Award as well.
Pros:
-Stable power
-Quiet
-Easy installation
-4x 12v rails @ 18a each
-High efficiency
-Low price
Cons:
-Might not have enough connections depending on system configuration
