  • Based on the new regulations in EU from 1st of July, the very successful B-series has been revised. A completely new circuit layout and new components make it compliant to the regulations. The biggest difference for the new B-series is that it now only has a single rail +12V DC out with a max current of 38A. This now means that all Cooler Master power supplies makes use of a single rail instead of multi rail.
