b450mhp vs a520m-k
For the R5 5500, the Biostar B450MHP is a solid AMD B450 socket AM4 micro ATX option. The Asus AMD Prime A520M-K is another good choice in the same socket. Both provide reliable performance for this model.
They’re both basic builds lacking VRM cooling solutions, offering limited upgrade options. Each features just two fan connections—one for the CPU and another for a case fan—meaning you can’t easily add more fans unless you use an external hub. The B450 provides improved rear connectivity with two extra USB 3.0 ports, though it technically allows overclocking; however, with Ryzen 5000 components, the gains would be minimal and unlikely to justify the effort. The A520 supports full PCIe Gen 3, making its two slots more valuable for future expansion cards. The B450 only supports Gen 2 in those ports. Overall, neither is a solid choice. Both are of very low quality and budget-friendly, but if you must pick one, opt for the cheaper option to maximize your funds.
I can suggest a few options depending on your needs. Which one are you interested in?
As @doubleflower mentioned, understanding your location and budget would help provide more tailored suggestions. Here’s a simple breakdown of B550 board options based on the testing by Hardware Unboxed:
These boards represent the most common performance levels for the Ryzen 9 3950X. The testing focuses on maximum cooling under heavy load, which is similar to what you'd see with the Ryzen 5950X. Unfortunately, five models failed this stress test. If you’re not planning to push them beyond normal limits, they still outperform your current choices—but if you want confidence in future upgrades (like moving to a Ryzen 9 5950X), these might not be ideal.
Generally, these boards cost about the same as the next ones on the list, but they often have weaker VRMs. If you’re okay with that, they can still work well for now. For those who don’t want to overclock, they’re still a solid pick and could support the Ryzen 7 5800X3D without issues.
In the US market, the Gigabyte B550M DS3H AC is available for around $88, which seems reasonable if you plan to upgrade later. MSI models like the B550M Pro-VDH or Asrock B550M Pro4 are solid choices if overclocking isn’t your goal. They can handle Ryzen 9 parts and even the Ryzen 7 5800X3D comfortably.
If budget is tight, the Gigabyte Aorus Elite series and B550M Mortar are decent options, especially if you’re not aiming for high performance. The MSI Bazooka or Asrock Steel Legend are technically strong but may need a well-designed case to avoid overheating.
The best value usually comes from the MSI B550-A Pro, Asus TUF Gaming B550M-Plus, and Gigabyte B550 Aorus Elite, which often drop below $120. The Asrock B550M Pro4 is currently $107, making it a good deal if you’re planning to add a 5800X3D later.
The top-tier boards—like the MSI B550-A Pro and Gigabyte B550 Gaming Edge WiFi—are excellent but can be pricey unless you find a good discount. The Asrock B550 Extreme4 and Gigabyte Aorus Pro are also available for around $120, though they’re still on the higher side.
