OCZ PowerStream 520 Pink Fondu

OCZ has provided us with a power supply (via a sale at Best Buy). Duh. Presenting the OCZ PowerStream 520. OCZ made a name for themselves in the memory market by creating top quality products. It looks like they aim to do the same in the power supply market. OCZ has been releasing products that help modders, overclockers, and enthusiasts to tweak their computers for absolute performance. While their memory built the OCZ name its products like the DDR Booster that gave the electron crazed (me) something to drool over. The PowerStream 520 makes it to my short list of power supplies I would recommend to friends, but I do not want to spoil the ending so we will save final judgment until, well, the end duh. On to what makes this power supply stand out.

Most of the features and specifications will be talked about in subsequent paragraphs. What I want to look at here is the simplest to understand part of a power supply, its power. When people buy new cases they often get a cheap power supply included with the case, these end up lasting a few months to a year before they die. The other thing that often happens is the buyer, thinking that they got a really good deal on their 450w power supply, neglected to read the fine print where it says that its 450w peak power and they never notice that the combined power from the 3.3v and 5v rails is less than 200w. There are a few key items that help a person select a quality power supply: first, the weight; second, the combined 3.3v and 5v power rails; and third, the warranty.

I'm all about one thing: reviews that are easy to understand and make sense of.
