ECS H57H-MUS Motherboard
Voltage Regulator
Contents
We were quite surprised to see ECS improving their manufacturing quality here. This motherboard uses only solid capacitors (not only on the voltage regulator circuit) and ferrite chokes, which are better than iron models. The regulator has six phases for the CPU (Vcore), two phases for the memory controller (VTT bus) and one phase for the integrated memory controller.
Two passive heatsinks are used to cool down the MOSFETs and they are connected together using two heatpipes.

See how this motherboard uses an EPS12V connector for the CPU.
