Upon closer examination of the PowerStream 420 I found other similarities to the Tagan units, such as the PCB color, heatsink design, and mini-circuit boards. This review at Tech-PC
will show many similarities. This is in no way a criticism of OCZ, as we know out-sourcing produces some of the best products available. Memory makers have done this for years, and countless manufacturers employ this manufacturing methodology as well. After all, do you really think your Sapphire X800Pro has a Sapphire VPU, memory and/or PCB?
Regardless, the reason I even make the association was that I was quite impressed with the Tagan TG480-U01 PSU after coming across several reviews. If you look closely at the PCB's in the photos below, and the arrangement of the parts, I'm sure you'll see the similarities. Of course OCZ Technology is all over the design of this PSU, as your about to see. The top photo is borrowed from the Tech-PC review, the bottom is one of many PowerStream PSU photos I've taken for this article;
Although it may not be obvious, the PCB's are the same beige color, the heatsinks are just about identical, and the mini circuit-board attached to the heatsink is nearly identical except for placement. While this may not be a revelatory observation, OCZ Technology chose a high quality European manufacturer to source many of the unit's parts. OCZ has certainly customized their unit transforming it into a work of utilitarian art.
