High-performance power supplies are not only required by gamers with high-end video cards. Even regular users with mid-range video cards and high-performance processors need to consider buying a better power supply.
We found ModStream power supply from OCZ a terrific product. If you are looking for a high-performance power supply, go for it. Its modular cabling system and the Velcro cable holders are awesome for organizing the cables inside the PC, thus providing a better airflow inside the PC case. Also, the position and size of the fan (on the bottom of the power supply, not on its back) added with the fact that the back of this power supply is completely opened makes it a terrific cooling device for your PC. In these days where overheating is a really common problem, this is particular important to note.
Another important detail is that it is cheaper than its sister series PowerStream. Actually PowerStream series, which has trimpots for overvoltage adjustments, is targeted to serious overclockers. If you are not that crazy of changing the voltages of your power supply but still want a high-performance and stable power supply with terrific cooling, ModStream is the way to go.
Also, OCZ gives a three-year warranty for this PSU. This shows the commitment of this company with the stability and quality of their power supplies.
