ECS H55H-CM Motherboard

Voltage Regulator

Since this is an entry-level motherboard, we wouldn’t expect the voltage regulator circuit to be great, however ECS seems to be worried in improving the quality of their products, because the main voltage regulator uses only solid capacitors and ferrite chokes, which is great (the voltage regulator for the memories still use an iron choke, although it also uses solid caps).

The main regulator is comprised of five phases, being three phases for the CPU (Vcore), one phase for the memory controller (VTT bus) and one phase for the integrated video controller.

The rest of the capacitors used on H55H-CM are a mix of Japanese (from Sanyo) and Taiwanese (from Teapo) caps.

In order to save costs, the voltage regulator circuit doesn’t come with a heatsink.
