Apple Macintosh SE/30 and SE AC-DC Power Supply

The 4XDC Special Edition is our flagship AC-DC power supply designed for the Apple Macintosh SE/30 and SE, built using all-new, modern components. It features quad DC power outputs with separate power modules for each of the machine's voltage rails, providing ample power to exceed the original specifications. It is an evolution of previous designs where the two +12 VDC rails are powered by their own power converter to minimize crosstalk between the sweep and disk rails. Some machine configurations may be more sensitive to this phenomenon, such as having a Micron Xceed internal grayscale video board installed.
