The GIGABYTE Ultra Durable 2 design utilizes all solid capacitors manufactured in Japan which are rated to last for at least 50, 000 hours in operational use. GIGABYTE Ultra Durable 2 motherboards also feature Ferrite Core Chokes with higher energy efficiency compared to more common iron core chokes & Lower RDS (on) MOSFETs which feature lower resistance, i.e. reduced power consumption & heat. Some motherboards in this segment feature the GIGABYTE Ultra Durable 2 Classic design, which features All solid Japanese manufactured capacitors & Lower RDS (on) MOSFETs.GIGABYTE has further enhanced on the CPU VRM area by increasing the power phases from 3 to a 4 phase design. This allows for more stable power delivery to the CPU, as well as help smooth out power ripple & noise which is important for clean CPU power delivery.
