AM5 Socket for Ryzen 7000, 8000, 9000 Series

The GIGABYTE B650M C V3-Y1 is a micro-ATX motherboard built around the AMD B650 chipset and the AM5 LGA 1718 socket. It accepts Ryzen 7000, Ryzen 8000 and Ryzen 9000 series processors. Four DDR5 DIMM slots support up to 192 GB of memory with dual-channel architecture. The board targets builders who want a compact platform for modern AMD CPUs.

Q-Flash Plus and EZ-Latch Simplify Build and

Q-Flash Plus lets you update the BIOS without installing a CPU, memory or graphics card, using a dedicated USB port on the rear I/O. The PCIe x16 slot features an EZ-Latch quick-release mechanism so a graphics card can be removed with one hand. Three M.2 connectors — one PCIe 4.0 x4 from the CPU, one PCIe 3.0 x2 from the CPU and one from the chipset — plus four SATA 6 Gb/s ports give flexible storage options.

5+2+2 Phase Digital VRM and 1 GbE LAN

A 5+2+2 phase digital VRM solution delivers power to the CPU socket. Realtek ALC897 provides 7.1-channel audio output. The rear panel includes a 1 Gbps Ethernet port, USB 3.2 Gen 1 Type-C, DisplayPort and HDMI for integrated graphics. Wi-Fi 6 802.11ax is also supported. The board uses standard micro-ATX mounting holes for chassis compatibility.

Questions about this item

How often will the 5+2+2 phases digital VRM need inspection or replacement under normal use?

The VRM is a solid-state power delivery circuit with no moving parts and no scheduled service interval; it lasts for the board's usable life unless physical damage occurs.

What is the first bandwidth limit reached when all three M.2 slots run sustained PCIe 4.0 x4 transfers?

The chipset provides only PCIe 3.0 x1 lanes to two of the M.2 connectors, so those slots saturate at PCIe 3.0 x2 speeds before the CPU-attached PCIe 4.0 x4 slot reaches its ceiling.

How loud does the chipset fan get and how much extra heat does the 1 GbE LAN add during all-day operation?

The board uses a fanless chipset heatsink and the 1 GbE controller draws minimal power, so acoustic output stays at case-airflow level and added heat is negligible.
