Cooler Master Silent Pro Hybrid 1050 Power Supply Review

I am often surprised when I get together with friends to see the power supplies driving their otherwise high end PC builds.  The same, otherwise sane, friends will often spend hundreds on video cards and high end CPUs but skimp on building a solid foundation, a proper power supply.  

Today we will be taking a look at the Silent Pro Hybrid 1050W power supply.  The Cooler Master Hybrid models are a different from most PSUs since concentrate on being both silent and versatile when it comes to total system cooling.  So what is the best way to get the best of both?  Read on and find out.

The Hybrid 1050W is the middle unit in the Silent Pro Hybrid Series sitting in the sweet spot between 850W and 1300W.  For most builds you can probably get away with an 850W but the 1050W allows for some future growth that may include multiple GPUs and some weekend overclocking.  The Hybrid 1050W is only available in this dust black finish accented by more silver/grey touches.

This is Cooler Master's first fully modular power supply line featuring a single +12v rail that operates at over 90% efficiency and carries the 80Plus Gold Certification.  Other highlights include flexible modular cables, Japanese Capacitors, 4-Way SLI/Crossfire support and dual CPUs.
