The 1200W ZM1200M from Silverstone provides the power you need for your most intense applications. It can continuously deliver the full 1200W at over 80% efficiency. Six +12V rails easily balance the heaviest power load. Switch from 6x17A rails to 1x95A rail depending on your needs. The auto-switching input can handle all common voltages so all you have to do is plug it in. The power connectors are fully modular. This lets you use only the connections you need. There's a handy carry bag for the extra cables, so they"ll still be around when you upgrade. The cables are all sheathed to make the inside of the case look neater, plus it helps with airflow. The efficient internal layout only needs an 80mm fan for cooling. This keeps the noise to a minimum, and it means more power can go to running your system. The system of your dreams needs power, the ZM1200M delivers.
