EVGA H55 Motherboard

Voltage Regulator

EVGA says that their H55 motherboard has a “6+1+1” voltage regulator circuit, however by following the traces on the printed circuit board we found out that the voltage regulator circuit has six phases indeed, with four of them for the CPU, one for the integrated memory controller (VTT bus) and one for the integrated video controller. Two other phases are available for the memories. So we couldn’t quite understand this “6+1+1” configuration announced.

All capacitors used on the voltage regulator circuit and on the rest of the motherboard are solid and all chokes are ferrite models, which are better than iron chokes. Please read our Everything You Need to Know About the Motherboard Voltage Regulator tutorial for more information.
