The ModStream is OCZ's new versatile power supply solution. This product comes in two different power ratings. The first is their entry level rated at 450W with a maximal peak of 550W and their more powerful version stands at 520W with a maximal peak of 620W.

Both units come with OCZ EZMod technology. While it sounds very advanced, EZMod is an advanced cable management system that facilitates the installation and gives you the option to only use the required cables. Most of their competition would call this a modular power supply. Labeling this feature as EZMod was quite a smart marketing move from their behalf that will without doubts give them an extra edge over the competition. Of course being easier to install wouldn't be enough to describe what EZMod can bring. Eliminating useless cables from your system will result in an optimal airflow and at the same time provide a cleaner computer system facilitating your upcoming upgrades or even provide an easier install of your water cooling system.

The front of the product features all the main connections. On the front inside you find two 6 pin connectors, 4 male Molex outputs along with the standard +12V output. In addition you find an extra 4-pin connector on the main +12V wire which features a clip. With the help of the sliding mechanism in between you can form a 24 pin connector for additional support for BTX mainboards.

In order to take full advantage of the EZMod technology, OCZ bundled all the necessary cables. The cables are pretty thick and are surrounded by a metal mesh used for the PowerShield EMI technology discussed later in this review. In addition the cables are surrounded with UV reactive tubing giving you a special glow in the dark effect when used with the appropriate lightning. Included cables are 1 SATA cable with 2 connectors, 1 PCI Express 6pin connector, 1 peripheral 4 pin connector, two cables of 2 peripheral 4 pin connectors, 1 peripheral 4 pin, 1 FDD 4 pin connector and at last one AC power cable.

I personally never believed in those new fan less power supplies, while most of them manage to provide a noiseless environment, the temperature within the system will always remain higher than average. Not that I would classify myself as somebody that makes out a big deal out of how my current system sounds, but a eliminating most noise would be a good advantage, especially for people spending hours in front of their system. With their PowerWhisper technology, OCZ qualifies the midstream as one of the quietest power supplies on the market today.
