Seasonic S12-550 Energy+,

Peak power supply with the performance of 550 W and high efficiency in excess of 80%.The cooling and air circulation is very quiet old 120 mm fan made from black plastic, which also contributes to the cooling of the system.The high quality of the witness box resources, which is made of sheet strength 0.8 mm and almost the entire surface of rear wall source is used for air passage.Speciality of the resources are 4 independent +12 V power branches, thanks to which it is possible to achieve a more even distribution of the burden of individual components to the source.
Very high quality can be seen even cabling, which is classically withdrawn stahovacími tapes and, moreover, is kroucená.Extra quantities of power connectors and venerable length of each cable sufficient for a fully equipped computer with many disks and drives.Of course, meet the standards for PFC low harmonic interference and re-radiation into the network needed to operate in the EU.
