ASUS PRIME B660-Plus D4 LGA 1700 ATX Motherboard

The ASUS PRIME B660-PLUS D4 is an ATX motherboard designed for builders who want to pair Intel 12th or 13th Generation processors with reliable DDR4 memory and fast PCIe 4.0 storage. It drops neatly into the LGA 1700 socket, giving you a solid platform for gaming, content creation, or a productivity workstation.

Four DIMM slots accept up to 128 GB of DDR4 memory, and the board can reach 5066 MT/s when you apply an overclock. Three M.2 sockets run on PCIe 4.0 lanes, so you can load your system with NVMe drives that boot quickly and handle large files without hesitation. Traditional drives and other storage devices can still join the build through the standard SATA ports.

For expansion, a full-length PCIe 4.0 x16 slot stands ready for a modern graphics card. A secondary PCIe 3.0 x16 slot operating in x4 mode and two PCIe 3.0 x1 slots give space for capture cards, sound cards, or other peripherals. Connectivity on the rear panel includes a USB 3.2 Gen 2x2 Type-C port, while the front-panel header supplies USB 3.2 Gen 1 Type-C for convenient case I/O. Network traffic moves through an integrated Realtek 2.5 Gb Ethernet controller, delivering low-latency links for online gaming or large file transfers.

Cooling and tuning features keep the system steady under load. VRM and M.2 heatsinks draw heat away from critical components, and Fan Xpert 2+ software lets you tailor fan curves to match your noise and temperature targets. Builders who enjoy personalized aesthetics can tap into Aura Sync support and addressable Gen 2 RGB headers to unify lighting across compatible components.

Whether you are assembling a home gaming rig, a streaming setup with multiple NVMe drives, or a small-business workstation that needs dependable throughput, this motherboard offers a balanced mix of performance, connectivity, and user-friendly tweaking tools.
