Overview
The ASRock A620M-HDV/M.2+ is a budget Micro-ATX motherboard built on the A620 chipset for AMD Ryzen 7000/9000 processors. With 6+2 power stages, 2x M.2 slots, and DDR5 support up to 64GB, it delivers the essentials for cost-effective builds without cutting critical corners.
Security advisory: check your BIOS
AMD published bulletin AMD-SB-7064 on 11 August 2026. It covers two high-severity flaws in AMD's firmware TPM: CVE-2026-6726, an information-leakage flaw that lets a forged TPM key be certified as genuine, and CVE-2026-6727, a timing side-channel. AMD scores them 8.5 and 8.3 on CVSS 4.0. Affected processors run from Ryzen 3000 to Ryzen 9000, plus Threadripper, Ryzen AI and Ryzen Embedded parts. Both attacks need local privileged access, so neither is remotely exploitable. The underlying flaw is in the Trusted Computing Group's TPM 2.0 reference code, which AMD ships as fTPM.
The fix arrives as a motherboard BIOS update. Windows Update will not install it. Check ASRock's security page and this board's own support page, install the latest BIOS, then look for an fTPM or TPM security fix in the release notes. Coverage varies by board, and we have not verified that a fixed BIOS exists for this one.
Before you flash: if this machine uses BitLocker, save your recovery key first. A firmware update can trigger BitLocker recovery, and Windows will then ask for a 48-digit key before it unlocks the drive. Our BIOS update guide covers the safe order.

Design & Build Quality
The ASRock A620M-HDV/M.2+ keeps things practical. The PCB is clean and the layout is straightforward, with essential heatsinking on the VRM. At this price point, you won't find extensive thermal armor or RGB, but ASRock has made sensible design choices that prioritize function over flash.
VRM & Power Delivery
The 6+2 power design is built for efficiency-class processors at stock settings. It handles everyday computing, office tasks, and light gaming workloads reliably. Stick to lower-TDP processors for the best experience — this board is designed for practical builds, not overclocking adventures.
Connectivity & I/O
There is no onboard WiFi, so you'll need a separate PCIe WiFi card or USB adapter if wireless connectivity is required. The rear panel features 6x USB, providing ample connectivity for peripherals, external storage, and high-speed devices.
Pros & Cons
Pros
- Adequate 6+2 power delivery for the target audience
- Outstanding value for the feature set offered
Cons
- No onboard WiFi or Bluetooth — requires a separate adapter
- Only 2 DIMM slots limits memory expandability
- Gigabit LAN feels dated compared to 2.5G on competing boards
- Basic ALC897 audio codec — consider a USB DAC for critical listening
Who Should Buy This Board?
Budget builders, office PC upgrades, and first-time builders entering the AMD Ryzen 7000/9000 platform. Delivers the essential features needed for everyday computing, light gaming, and entry-level workstation tasks without breaking the bank.
Build Tips & Recommendations
- AM5 retains the AM4 cooler mounting holes, so your existing AM4 cooler will work. Just make sure to use the AM5 backplate that comes with the motherboard.
- For AMD AM5, DDR5-6000 CL30 is the sweet spot for Ryzen — it aligns with the Infinity Fabric 1:1 ratio for optimal performance. Enable EXPO in BIOS after installing.
- Install your primary NVMe SSD in the top M.2 slot closest to the CPU socket for the fastest connection. The 2x M.2 configuration is sufficient for most builds.
- This Micro-ATX board fits both Micro-ATX and ATX cases. If building in a smaller case, verify GPU length clearance before purchasing a large graphics card.
- Always update to the latest BIOS before installing components for the best compatibility, especially with newer CPUs and RAM kits. Download the BIOS file to a USB drive and use the flashback feature if available.
