Corsair CS550M

An excellent choice for desktop systems, where high reliability, along with low noise levels, and flexible modular cabling, are of the utmost importance. Though designed for a basic to mid-range system with discrete graphics card, the supply’s prestigious 80 PLUS Gold certification guarantees high efficiency, which economically reduces excess heat and subsequent energy costs, even at high loads. The supply’s stylish design with opaque finish, virtually transforms any system into a great looking professional result. 

The flat cables are modular, so you will only use those you truly need, and rid yourself of the clutter while maximizing the airflow through the chassis, in the process. The thermally controlled 120mm cooling fan remains near silent during periods of standard workloads, and secures effective direct expulsion of warm air from the case when pushed hard. 

Setting up a desktop system of practically any size poses no difficulty, thanks to the flat, sleeved cables, sufficiently long to satisfactorily handle such a task. A large voltage tolerance proves advantageous during stretches of power fluctuations. Active Power Factor Correction is of course included as well.
The power supply is also fully compatible with the latest generation of Intel Haswell processors.
