Introduction:::...

When it comes to shopping for a new Power Supply these days. It almost seems as though your sifting through an entire beach of sand for that perfect grain. There are so many available on the market, that it makes a tough task. In this day and age, you don't want just any Power Supply either. You may want one for that hot Lan gaming system your plan on toting around, you may want one for that slickly modded case you have, or you may just want one just for horsepower's sake. Whatever it is you want one for, it's next to impossible these days, in my opinion anyway, to choose the perfect one, as they are so many.

It was tempting to assume that the Modstream 520 shared the innards of the PowerStream 520 but looking at the specs they are quite clearly different in their outputs.

As you can see above, and from the pictures to come, this PSU is no slouch in the features department. It is a Modular Power Supply, meaning you can add or remove cable sections as needed. Always a big bonus for the Modder or those with tight confines.

OCZ named the modular aspect of this PSU the "EZMod cable management system". What isn't listed above, but is listed on the box, is a 620 Watt Peak load, Copper shielded leads, UV cables, and blue LEDs in the fan. Also, just for mentioning sake, there is also a 450 Watt version of the Modstream.
