ECS H55H-I Motherboard
Voltage Regulator
Contents
We always like to analyze the voltage regulator
circuit, as it gives us an idea of the manufacturing quality of the motherboard. H55H-I voltage regulator circuit has five phases, three for the main CPU voltage (Vcore), one for the VTT voltage (used for feeding the memory controller and L3 cache inside the CPU) and one for the video controller. Four of the phases use ferrite chokes, but one uses an iron choke.
On the other hand, all capacitors used on the voltage regulator circuit are solid. The electrolytic capacitors used on the other circuits from the motherboard are Taiwanese from OST.
The voltage regulator circuit doesn’t come with a heatsink.

This motherboard uses an ATX12V connector for the CPU.
