Chipsets

The chipset is the motherboard's controller. It determines available features (PCIe lanes, USB ports, NVMe support) and whether a CPU generation is supported. Matching socket alone isn't always enough — the chipset must support your CPU.

Socket vs Chipset

The socket (e.g., LGA1700) is the physical CPU slot. The chipset (e.g., Z790, B760) controls features. Both must be compatible: CPU socket must match the motherboard socket and the chipset must support that CPU generation.

Memory (RAM)

Motherboards support DDR4 or DDR5 (rarely both). Check memory type and maximum speed. Kits are sold as 2x or 4x modules; ensure the motherboard has enough slots and supports the kit speed.

VRM & CPU Power

VRMs deliver power to the CPU. High-end CPUs need robust VRMs and cooling on the motherboard. If you pick a high-TDP CPU, choose a motherboard with a strong VRM (look for 8+ phase designs for overclocking).

PSU Sizing

Estimate total wattage from the CPU + GPU + other components and add a safe buffer (≈20–30%). Use the recommended PSU wattage shown in the builder to choose a quality PSU with some headroom.

CPU Cooler Compatibility

Check motherboard cooler mounts (AM4, LGA1700, etc.) and case cooler height. Many coolers support multiple mounts but may require a mount kit for newer sockets.

Storage & PCIe

NVMe M.2 slots may be wired as PCIe 4.0 or 5.0 and sometimes share lanes with SATA or other M.2 slots. If you need multiple fast drives, check M.2 slot counts and bandwidth.

Practical Tips

• Start with the CPU — it drives motherboard choice.
• Pick motherboard after CPU to ensure chipset compatibility.
• Match RAM type/speed to board and consider dual/quad-channel kits.
• For first builds, favor well-reviewed motherboards from reputable brands.

GPU Clearance & Case Fit

Modern GPUs can be very large and heavy. Before buying, check your case’s maximum GPU length and width clearance. Small micro-ATX and mini-ITX cases may not fit 3-slot GPUs. Ensure your PSU cables and front fans have room too. Tip: Always check your case’s official spec sheet for GPU clearance in millimeters.

BIOS Updates

Some older motherboards require a BIOS update before they can run newer CPUs — even if the socket matches. If your CPU isn’t recognized, check the motherboard manufacturer’s site for BIOS version support lists. Some boards include a BIOS Flashback feature that lets you update without a CPU installed (very useful when moving from 12th → 13th Gen Intel or older AMD AM4 setups).

PCIe 5.0 Readiness

PCIe 5.0 doubles bandwidth over PCIe 4.0, enabling faster GPUs and NVMe SSDs. Not all boards or CPUs support it — check specs before buying. Even if your current GPU is PCIe 4.0, choosing a PCIe 5.0 motherboard ensures future upgrade flexibility.
