  • ValuePraisedBuyers see it as one of the cheaper ways to get X570 and PCIe 4.0.

Questions and answers

Which is better for a Ryzen 7 5800X?
The ASUS PRIME X570-P is the better match. It gives PCIe 4.0 and stronger power delivery headroom for an 8-core chip. The A520M K V2 will run it, but with PCIe 3.0 and a simpler VRM.
Does the Gigabyte A520M K V2 support PCIe 4.0?
No. Its main expansion slot is PCIe 3.0 x16, and its M.2 slot runs at PCIe 3.0 speeds. The X570-P offers PCIe 4.0 on both.
Is the ASUS board worth the extra money?
Yes if you want PCIe 4.0, four memory slots, or plan a high-end CPU. If you are building a budget Ryzen 5 system, the Gigabyte at $88.90 at Newegg as of November 7, 2026 saves money with little real loss.
Which board lasts longer?
Both should last many years. The X570-P has a beefier VRM and more slots, so it ages better with future CPU and storage upgrades. The A520M K V2 is fine for a fixed budget build.
Can I use 128 GB of RAM on the Gigabyte board?
No. The A520M K V2 has two DIMM slots and tops out at 64 GB. The ASUS PRIME X570-P has four slots and supports up to 128 GB.
Which fits a small case?
The Gigabyte A520M K V2 is Micro-ATX and fits many compact cases. The ASUS PRIME X570-P is full ATX and needs a larger case.
