Voltage Regulator

The CPU voltage regulator circuit of the Gigabyte G1.Sniper 5 has 16 phases for the CPU. The voltage regulator uses an IR3563B controller chip (digital design). This controller provides eight phases, and each of these phases are connected to a phase doubler integrated circuit, creating the final 16 phases. One IR3550M chip (which combines the low side and the high side transistors in a single package) is used per phase.

Another interesting feature is the voltage regulator cooling system. It is an active cooler, with one heatpipe and a 40 mm fan. It is also prepared for a liquid cooling system, as shown in Figure 14.

The Gigabyte G1.Sniper 5 uses high-end solid capacitors and all coils on this motherboard are ferrite ones. If you want to learn more about the voltage regulator circuit, please read our tutorial on the subject.
