    Cooler Master B Series - 400W - B400 Ver.2 Psu Product Description

    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 30A. This now means that all Cooler Master power supplies makes use of a single rail instead of multi rail.

    Main Features:

    • 80 plus EU 230V certified
    • Silent 120mm Sleeve fan with intelligent fan-speed control, to enhance longevity and help reduce noise in power unit.
    • Green power design to meet ErP 2013 Lot6 & all new CE energy saving regulation
    • Powerful +12V rail for strong resistance to any overloading
