This article covers ASRock マザーボード B650M.

Overview

The ASRock B650M-HDV/M.2 is a budget-oriented Micro ATX motherboard designed for AMD Ryzen 7000 series processors. Built on the B650 chipset, it brings DDR5 memory and PCIe 4.0 support at an entry-level price point. With an 8+2+1 phase Dr.MOS power delivery, it provides stable power for everyday computing and light gaming. This motherboard is a solid choice for cost-conscious builders who want to enter the AM5 platform without breaking the bank.

Compatibility Guide

This motherboard features Socket AM5, compatible with all Ryzen 7000, 8000, and 9000 series CPUs. It supports dual-channel DDR5 memory up to 64GB via two DIMM slots, with support for XMP and EXPO profiles for overclocking. The Micro ATX form factor (244mm x 213mm) fits in most Micro ATX cases. Storage options include one M.2 slot (PCIe Gen4 x4) and four SATA 6Gbps ports. Expansion: two PCIe 4.0 x16 slots (one runs at x4 mode when second is populated) and one PCIe 4.0 x1 slot. Power connectors required: 24-pin ATX and 8-pin CPU. Note that integrated graphics output is available via HDMI 2.1 and DisplayPort 1.4 when using a Ryzen 7000 G-series or 8000G series APU.

Best Use Cases

Budget Gaming Build: Pair with a Ryzen 5 7600 and a mid-range GPU like RTX 4060 or RX 7600 for a capable 1080p gaming rig. DDR5 support ensures future-proofing for games that benefit from faster memory. Compact Office/Home PC: The Micro ATX size allows for a small footprint case. Use the integrated graphics from a Ryzen 5 7600 or 8500G for office tasks, web browsing, and light photo editing. 2.5G LAN is great for NAS or fast internet. Entry-Level Content Creation: With a Ryzen 7 7700, you can handle 1080p video editing and rendering with decent performance. The PCIe 4.0 x16 slot supports high-speed SSDs for fast project loading.

Things to Consider

Limited Memory Slots: Only two DIMM slots means you must choose capacity carefully (e.g., 2x32GB for 64GB). Upgrading later may require replacing DIMMs. Single M.2 Slot: Only one native NVMe slot. For additional NVMe drives, you'll need to use a PCIe adapter card or rely on SATA SSDs. VRM Capabilities: While adequate for Ryzen 5 and Ryzen 7 CPUs, the 8+2+1 phase Dr.MOS may struggle with high-end Ryzen 9 processors under sustained heavy loads. Stick to 65W-105W TDP CPUs for best results. No Built-In Wi-Fi or Bluetooth: If you need wireless connectivity, you'll have to add a separate Wi-Fi adapter or a M.2 E-key module (if you have an adapter). Audio Codec: Realtek ALC897 is a basic HD audio codec. Audiophiles may want an external USB DAC. ## Specifications | Item | Specification | |------|---------------| | Socket | AMD Socket AM5 | | Chipset | AMD B650 | | Form Factor | Micro ATX (244mm×213mm) | | Memory Type | DDR5 (non-ECC, unbuffered) | | Memory Slots | 2 x DIMM, Dual Channel | | Max Memory | 64GB | | Memory Speed | DDR5 6400+(OC), XMP/EXPO supported | | PCIe x16 Slots | 2 (PCIe 4.0 x16), 1 (PCIe 4.0 x1) | | M.2 Slots | 1 (PCIe Gen4 x4) | | SATA Ports | 4 (SATA 6Gbps) | | Graphics Output | HDMI 2.1 (4K120Hz), DP 1.4 (4K120Hz) | | LAN | Dragon 2.5 Gigabit Ethernet | | Audio | Realtek ALC897 (7.1ch HD Audio) | | USB Ports | 1x USB 3.2 Gen2 Type-C (rear), 6x USB 3.2 Gen1 Type-A (2 rear, 4 front), 8x USB 2.0 (4 rear, 4 front) | | Power Phase | 8+2+1 Dr.MOS | | Supported CPU | AMD Ryzen 7000/8000/9000 Series | | Power Connectors | 24-pin ATX, 8-pin CPU |
