It is advisable to install all of the mount screws on the chassis motherboard tray. This way motherboards are securely mounted and problem free. Vibration can be eliminated with securely mounted components. The screw placements are intended to make it possible to swap RAM and even the processor without removing the motherboard. Add-in cards also need a secure motherboard which aligns with the slots.

The typical EPS12V and ATX12V are common with recent motherboards. Realistically the 8-pin EPS12V has plenty of power making the ATX12V absolutely pointless.

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. Make sure that the fan is not fouled so that when the southbridge is loaded with work that it can remain cool and maintain operations.

The Ryzen 2000 series processors can support up to DDR4-2933. The Ryzen 3000 series and above processors can support JEDEC DDR4-3200. DDR4 sticks spans 4GB to 32GB capacity. With available 32GB memory it is now possible to install 128GB.

The Ryzen 3000 CPU provides 4 lanes PCIe 4.0 to the X570 PCH which affords 8 GB/s of bandwidth. Similarly the 4 lanes PCIe 4.0 for the SSD affords the same 8 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. The X570-A PRO is such a powerful platform it can be relevant for 3-5 years.

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.

The AMD X570 Motherboard Overview: Over 35+ Motherboards Analyzed

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 ASM1061 chip to provide 2 more. The X570 does support as many as 12 SATA channels not counting the CPU SoC lanes. So far nobody has a motherboard with enough lanes without resorting to PCie cards. The 8 PCIe 4.0 lanes from the X570 could provision the secondary slots easily. This would allow the additional 8 SATA ports to be available. MSI et al do not do this.

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 and widely available for peripherals. USB 2.0 headers persist internal perpherals.

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. SATA cards are common for those numerous hard disks from the older designs which had 2 or 4 SATA ports. The X570 can provide even more SATA ports but generally this feature is not used.

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 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. USB 2.0 ports are available for the perfunctory keyboard and mouse with the PS/2 port available for old peripherals.
