MSI X570-A Pro 12-pin connector for CPU power supply.
You're considering an MSI X570-A PRO motherboard with 12 CPU power pins. Your PSU only has 8 pins, but you're planning to use all 12 for proper power delivery. You're thinking about adding a 2x+12V and 2x Grounds rail to make it work, and you already have a Ryzen 5 2600X and a Radeon RX570. The manual suggests checking the troubleshooting section for details on pin requirements. It seems the extra 4 pins are likely necessary for the board to power on correctly. You're wondering if connecting the additional pin to your PSU's rails would be sufficient before purchasing.
The additional four-pin connector is not mandatory; it's mainly for intense overclocking. An 8-bit EPS can deliver up to 384 watts, or more if needed.
You don't have to add the extra 4-pin, and skipping the X570-A Pro would be a smarter choice—it's likely more affordable and just as good.
Thanks guys. Your knowledge is very much appreciated. The price difference is only £5, with the B550-A Pro being the more expensive of the 2 boards. And the B550 Board won't support 2nd Gen Ryzen will it? I was holding out for the B550 chipset boards which is why it's taken me until July to even consider which board to buy. But after reading on AMD's site that there is no support for 2nd Gen Ryzen on the B550 Chipset I decided to opt for the X570 boards instead.
Suggested to use b550 with the exception of missing second-gen support. The X570 is the only one going back a generation, sadly. @AdamC advise against cheap MSI boards for the X570. https://uk.pcpartpicker.com/products/mot...rice&c=138 Updated June 20, 2020 by Fasauceome
It's accurate that the B550 only works with Zen 2 processors (like Ryzen 3000 series except the 3200G and 3400G). The ASUS Prime X570-P offers a more basic setup but delivers decent power delivery, comparable to their premium models such as the Strix X570-F. It's a strong choice for its price point. I didn't realize the CPU was mentioned in the first post.
I evaluated the ASUS Prime X570-P, but honestly the cost was a deterrent. It’s roughly £30 higher than the MSI X570-A Pro. That amount could have been used for some good DDR4 RAM. I won’t purchase RAM until August. Next month’s only need will be RAM, which will be the main item I buy then. After that, I’ll have a setup capable of running the games I want. I won’t push the system to overclock much, so strong CPU power delivery shouldn’t be an issue. It’s been tough playing recent releases with decent settings on my old Pentium D925—even after pushing it to 3.4GHz. I built this machine over a decade ago and haven’t upgraded anything else except adding 2GB of RAM for Windows 10. I’m excited about getting PCIe x16 3.0 for the graphics card instead of the current x16 1.0, and switching to SATA 6GB/s for SSDs and HDDs rather than the older 1.5Gb/s. Those two upgrades alone will significantly boost performance, regardless of the extra cores and threads from my Ryzen 5 2600X.
