MSI X570-A PRO

The MSI X570-A PRO is a standard ATX motherboard for socket AM4.

  • Standard ATX 9″ x 12″
  • Socket AM4
  • AMD Ryzen 2000 and 3000 support / AMD Ryzen with Radeon Vega
  • Supports PCI Express 4.0 with a Ryzen 3000 series processor
  • 4x DDR4 up to 128GB
  • PCIe x16 slot
  • 3x PCIe x1 slots
  • PCIe x4 slot
  • 2x M2 slots
  • Audio Boost 4 technology with Nahimic 3 software enhancement for immersive experiences
  • Turbo USB 3. 2 Gen2 with reversible type-c connector
  • graphics desktop processors for AM4 socket
  • Frozr heatsink with patented fan design – propeller blade technology and double ball bearings

It is advisable to install all of the mount screws on the chassis motherboard tray. This way motherboards are securely mounted and problem free.

The MSI X570-A PRO is an outstanding design for the base model X570 from MSI. The 8.2 regulators are not stressed much with the 65W and 105W processors. The fan on the X570 southbridge does not even spin up in most situations.

The MSI X570-A Pro wants an EPS12V and an ATX12V cable rather than dual EPS12V. Generally the motherboard will function fine with a single EPS12V cable which can provide 300W of power easily.

The Ryzen 2000 series processors can support up to DDR4-2933. The Ryzen 3000 series processors can support up to DDR4-3200. DDR4 spans 4GB to 32GB capacity.

The Ryzen 3000 CPU provides 4 lanes PCIe 4.0 to the X570 which affords 64 GB/s of bandwidth. Similarly the 4 lanes PCIe 4.0 for the SSD affords the same 64 GB/s of bandwidth. The MSI X570 is so powerful that it may take a couple of years for M.2 SSD vendors to catch up with it.

PCIE_2 and below are provided by the X570 PCH. For X570-A PRO the BIOS should be set for x16 as this model is not configured for dual graphics. The BIOS shows options that may be possible on more expensive models of the X570. Check for specific features.

The MSI X570-A PRO has an Infineon IR35201 8-phase voltage controller in a 4+2 phase mode. It also has IR3598 phase doublers. It is essentially a 6 phase design that’s taken to a 4+4+2 phase configuration via the use of doublers. ONSemi 4C029N 46A MOSFETs are used for vCore. The SoC MOSFETs are QA3111N6N from UBIQ, which are rated for 59A. The expected vCore power output is 368W, so any 65W or 95W AM4 processors will be handled easily.

Adequate air cooling is expected with the MSI X570-A PRO as the regulator heatsinks are comparatively limited. Best best with a mid-tower chassis is 1-2 front intake fans and 2-3 top/rear exhaust fans. The Corsair SPEC-01 is a solid choice with added fans.

The metal reinforced primary slot means that graphics cards can be swapped out many times without much worry. More and more motherboards are now using stronger meta reinforced video cards slots.

Except for the primary slot, all of the PCIe slots are PCI Express 3.0 from the X570 southbridge. Slot PCIE_2 will be disabled if slot PCIE_4 is used. Dual fan cards are generally dual slot friendly but some shorter single fan cards are now 2.75 slot width. Most modern mid tower ATX chassis have room for dual fan cards and many can even fit longer triple fan cards.

M2_1 supports NVMe PCIe only. SATA port 0 will be disabled when a SATA SSD is installed in the M2_2 slot. This is not necessary as the X570 has adequate SATA support.

The MSI X570-A PRO southbridge is configured 4 SATA channels and there is a ASmedia SM1061 chip to provide 2 more. The X570 does support as many as 8 SATA channels so the ASmedia chip wastes a PCIe lane that could have been better used for a slot.

There are two 9-pin USB 2.0 headers and two 19-pin USB 3.2 headers on the front edge. USB 2.0 splitters are low cost for peripherals.

With more SATA ports the is now an option for a BD drive to perk up media playback. The MSI X570-A Pro has 6 SATA ports so all 5 drive bays on the HAF 932 can be used in addition to the BD drive. SATA cards are common for those numerous hard disks.

The fan headers are placed along the bottom edge. Extension cables may be needed for some situations. Its advisable to have several fans installed so that a machine will have a long service life. A front intake fan with a rear/top exhaust fan is the most common configuration.

The BIOS flashback feature is very helpful as this does not require a CPU to be installed to install an update. AGESA 1.0.0.4 was not available originally to support the R5 2400G processor. The R5 3600 processor is immediately supported.

There is an HDMI connector on the I/O shield for APU users who wish to use the Vega graphics. HDMI is a popular connector with television, cable TV and BD players etc.

The Realtek ALC1220 HD audio codec provides five 3.5mm connectors in addition to the S/PDIF optical connector for media center use.

The introduction of USB 3.2 with a Type-C connector finally allows the AMD to support the upcoming USB 4.0 standard which will mandate the new reversible connector looking forward.
