A long heatpipe is used to link the heatsinks of the PCH and VRM together, although we would have preferred them to be separate as the Patsberg PCH only has a relatively small TDP of 6.7W which is puny compared to the heat output of the IR3550 powerstages.

A sensible 12-phase design is used for CPU power regulation, featuring Ferrite Core Chokes that we usually see on higher end motherboard offerings.

The new International Rectifer IR3550M PowIRstage I/C, rated at 60A each in a space saving form factor, is touted to have less electrical leakage over traditional MOSFET implementations thus capable of higher efficiencies and output.

Over at the memory slots, we see sensibly placed buttons for Power/Reset/Clear CMOS and the inclusion of a PORT-80 diagnostic LED. Voltage probe points for the common overclocking parameters are available as well, although spaced a bit too close together for the average multi-meter probe.
