Introduction

The M series PSU have the following main features, one 12V rail, flat modular cables and silence of course.
If this PSU can perform well I think we might see the feature of power supplies in todays review. The flat cables for example make the case look nicer and increases airflow while the single 12V rail should work both for casual users and heavy overclockers.

All the boxes look the same except for the voltage definition. On the front you got a picture of the unit without any cables connected and on the back you can read the specifications and features.

Inside each box you will find a cd with a user manual, a warranty card, and a slip with some information. The modular cables and power cable are wrapped up with a zip tie. If you look close you will see that the stack of modular cables is as big as just one power cable. This really shows the difference in size on normal PSU cables and these.

If you click on the left picture you will clearly see how thin and small the modular cables actually are. I personally find this feature to be perfect as I got enough crap in my setup as it is. The chassis of the PSU is black and the cables that are stuck on the PSU are ofcourse sleeved.
