The Ryzen 5 2400G is a 2018 Raven Ridge APU on AMD’s AM4 socket, and by 2026 most of its natural motherboard partners are discontinued and only available through remaining new-old-stock or the used market — prices below reflect that reality, not fresh MSRPs. B450 and X470 boards give the fullest feature set (the 2400G is unlocked and supports memory overclocking on these chipsets); budget A320 boards work but drop official RAM/CPU overclocking support. Whichever you pick, flash to the latest available BIOS before installing the CPU — some older B450 boards shipped before Raven Ridge support was added.

The picks, in detail
ASRock B450M Pro4
One of the most commonly recommended budget B450 boards for the 2400G, with a straightforward micro-ATX layout and passive VRM cooling.
- AM4 socket, AMD B450 chipset
- DDR4 up to 3200+ MT/s
- 3+3 phase VRM with passive cooling
- Micro-ATX form factor
- Long community track record specifically with Raven Ridge APUs
- Straightforward BIOS with good memory-overclock headroom for the price
- Now scarce — pricing on the current R2.0 revision runs well above its 2018 launch price
- Used listings vary wildly in condition; check for bent pins and burnt VRM areas
ASUS Prime B450M-A II
ASUS’s budget-friendly B450 board, with a simple feature set that still covers everything a 2400G build needs.
- AM4 socket, AMD B450 chipset
- DDR4 up to 4400 MT/s (OC)
- NVMe M.2 support
- USB 3.2 Gen 2, BIOS Flashback
- Cleanest current pricing of the B450 boards here for in-stock units
- BIOS Flashback lets you update firmware without a CPU installed — useful for buying used
- Pricing swings widely between sellers (seen as low as $29 and as high as $336) depending on stock and demand
- Fewer VRM phases than the Gigabyte Aorus Elite
Gigabyte B450 Aorus Elite
A step up in VRM quality and features from the budget boards here, popular for buyers who want more overclocking headroom out of the 2400G’s unlocked multiplier.
- AM4 socket, AMD B450 chipset
- Hybrid Digital PWM design
- Dual M.2 with thermal guard
- RGB Fusion 2.0
- Stronger VRM than the ASRock or ASUS budget boards, better suited to sustained overclocking
- Dual M.2 slots give more storage flexibility
- Pricier than the ASRock/ASUS budget boards for a platform that’s already aging out
- ATX form factor needs a full-size case, unlike the micro-ATX options here
MSI B450M PRO-VDH MAX
MSI’s budget micro-ATX B450 offering, frequently the cheapest new-stock B450 board still findable in 2026.
- AM4 socket, AMD B450 chipset
- DDR4 support with 2nd/3rd Gen Ryzen compatibility called out specifically
- M.2 and SATA 6Gb/s
- D-Sub/DVI/HDMI video outputs for the 2400G’s integrated Vega graphics
- Often the lowest-priced B450 board in current stock
- Explicitly lists 2nd Gen Ryzen (including the 2400G) compatibility
- Basic feature set even by budget-B450 standards
- Pricing has swung from under $50 to nearly $190 depending on availability — shop around
ASRock A320M-HDV
The true budget option — an A320 board that skips official overclocking support but covers everything a non-gaming or HTPC-style 2400G build needs.
- AM4 socket, AMD A320 chipset
- 2x DDR4 DIMM slots
- D-Sub, DVI, HDMI outputs
- No official CPU/RAM overclocking support
- Cheapest chipset tier on this list, ideal for a budget or HTPC build
- Fine for running the 2400G at stock speeds with its integrated Vega 11 graphics
- No official overclocking support — skip this if you want to push the 2400G’s unlocked multiplier or run faster memory
- Only 2 RAM slots limits future upgrades
Biostar B450MH
A lesser-known but genuinely B450-chipset budget board, worth considering when the bigger three brands are out of stock.
- AM4 socket, AMD B450 chipset
- 2x DDR4 slots, up to 32GB
- 8-channel audio, Gigabit LAN
- 4x SATA3, 1x M.2
- Real B450 chipset (unlike A320 boards) at a comparable budget price when in stock
- Simple, no-frills layout with everything the 2400G needs
- Frequently out of stock at major retailers — availability is the main obstacle, not price
- Smaller brand with less community documentation than ASRock, ASUS, or Gigabyte
ASRock X470 Master SLI/AC
A step up to the X470 chipset — more VRM headroom and features than any B450 board here, for buyers who want to actually push the 2400G’s unlocked multiplier and memory speed.
- AM4 socket, AMD X470 chipset
- ATX form factor
- Built-in Wi-Fi/AC (the “/AC” suffix)
- SLI/CrossFire multi-GPU support
- Strongest VRM and overclocking headroom of any board on this list
- Built-in Wi-Fi saves a card slot if that matters to your build
- No longer sold new in most regions — used/remaining-stock only
- ATX size needs a full case, and SLI support is irrelevant paired with a 2400G’s integrated graphics
ASUS Prime X470-Pro
ASUS’s mainstream X470 board, now mainly found on the used market at a real discount to its original launch price.
- AM4 socket, AMD X470 chipset
- ATX form factor
- Aura Sync RGB
- 5-Way Optimization auto-tuning
- Full X470 feature set and OC headroom at a used-market discount to the ASRock X470 board here
- ASUS’s BIOS and software ecosystem is generally considered the most polished of the major motherboard brands
- Used-only at this point — inspect seller feedback and photos closely
- No built-in Wi-Fi, unlike the ASRock X470 Master SLI/AC
Buying tips
- Flash the BIOS to the latest available version before installing the CPU if you can borrow a compatible Ryzen chip — some early B450 boards shipped before Raven Ridge (2000-series) APU support was added.
- The 2400G is unlocked, so a B450 or X470 board (not A320) is worth the extra cost if you want to push memory speed or the CPU multiplier.
- Skip B550 boards for this build — AMD’s official support list excludes Raven Ridge (2000-series) APUs like the 2400G on B550, and while a handful of boards unofficially work with a specific BIOS, it’s not a reliable bet. Stick to B450, X470, or A320.
- Most of these boards are now out of production, so pricing and availability change fast — treat any single listing’s price as a snapshot, not a guarantee.
- Confirm your case supports the board’s form factor: the micro-ATX options here (ASRock B450M Pro4, ASUS Prime B450M-A II, MSI B450M PRO-VDH MAX, Biostar B450MH, ASRock A320M-HDV) fit more cases than the full-ATX Gigabyte Aorus Elite or either X470 board.
