GIGABYTE B660 Gaming X DDR4 Intel Motherboard

The GIGABYTE B660 Gaming X DDR4 is an ATX form-factor motherboard built around the Intel B660 Express chipset, designed to support 12th Gen Intel Core, Pentium Gold, and Celeron processors via its LGA1700 socket. It is a strong foundation for a mid-range gaming PC, pairing solid power delivery with a feature set that covers fast networking, ample storage, and configurable RGB lighting. Power delivery is handled by an 8+1+1 phase hybrid digital VRM design with DrMOS components, supported by fully covered heatsinks over both the VRM area and the M.2 slots. Three M.2 slots support NVMe drives over PCIe 4.0 or PCIe 3.0 x4, each protected by a Thermal Guard heatsink to manage drive temperatures under sustained workloads. An additional four SATA 6Gb/s ports extend storage capacity further, with RAID 0, 1, 5, and 10 support. Networking is provided by a Realtek 2.5GbE LAN chip supporting 2.5 Gbps, 1 Gbps, and 100 Mbps speeds with bandwidth management tools for prioritising game traffic. Onboard audio uses a Realtek audio CODEC with high-quality capacitors and an audio noise guard for cleaner output across 2/4/5.1/7.1-channel configurations, served by six rear audio jacks. For expansion, a primary PCIe x16 slot operates at full x16 bandwidth for the primary GPU, complemented by two additional PCIe x16-form slots running at x1. Memory support extends across four DDR4 DIMM slots in dual-channel configuration, with a maximum capacity of 128 GB (Non-ECC Unbuffered). Connectivity at the rear panel includes one HDMI 2.0 port and one DisplayPort for display output (dependent on CPU integrated graphics), one USB 3.2 Gen 2 Type-A port (red), two USB 3.2 Gen 1 ports, and five USB 2.0/1.1 ports. A front-panel USB 3.2 Gen 2 Type-C header supports up to 10 Gb/s transfer speeds. RGB FUSION 2.0 enables control over addressable LED and RGB LED strips, while Smart Fan 6 provides multi-sensor fan curve management with hybrid fan headers and FAN STOP functionality. Q-Flash Plus allows BIOS updates without a CPU, memory, or graphics card installed.
