Buying Guide for the Best B450 Motherboards
Unlike what you would expect from a fairly budget-friendly motherboard lineup, B450 motherboards for AMD are highly versatile. These can work with 1st gen, 2nd gen, 3rd gen, and even the latest 4th gen AMD Ryzen processors while offering you with CPU and memory overclocking capabilities. We are here with the following detailed buying guide for the best B450 motherboards:
1. Form Factor
Starting with one of the most basic yet highly important factors, the form factor of the Motherboard. Different motherboards have different sizes or form factors. Three most popular used motherboard form factors are ATX, micro ATX and mini ITX. ATX is the largest and highly common, whereas mini ITX is ideal for compact builds like Home Theater PC (HTPC). With a larger size, you generally get more connectivity options making it ideal for gamers and content creators.
2. Socket
It is quite important to ensure that the motherboard that you are getting physically supports the CPU that you want to get. As for the motherboards stated above, all of them come with the AMD AM4 socket, which is used by various AMD Ryzen processors ranging from 1st gen to the latest 4th gen CPUs.
3. Chipset
Even if your motherboard has the right socket, it may not function with the CPU that you want to use until and unless it also has the right chipset. As you would have guessed, all the different motherboards stated in this list come with a B450 chipset. This chipset can be used with all AMD Ryzen processors of all generations. Although, you may not get all of the latest features offered by the latest AMD Ryzen 5000 series CPUs.
4. Memory Slots
While a B450 motherboard will work with almost all AMD Ryzen CPUs launched till date, you still need to ensure that it can handle the memory kit that you wish to use. Thus, make sure to check the number of included memory slots. Usually, you will find most B450 motherboards to offer 4 memory slots with mini-ITX models including 2 memory slots. Other than the number of slots, you should also check their maximum compatible memory speed. While some of them may work only with up to 3200 MHz RAM, others might even support 4400 MHz for the best possible performance. You should also check the maximum RAM capacity supported by your board since while some may work with up to 64 gigs of RAM, higher-end boards can even support 128 gigs of RAM in total.
5. PCI-E Slots and Expansion Slots
If you want to add additional functionality to your computer’s motherboards, then using an expansion card can be a great idea. These cards are connected to the PCI-E slots or the expansion slots of your motherboards. Other than your computer’s graphics card, an expansion slot can also be used for adding networking cards, sound cards, storage cards, and much more. While smaller ITX boards come with a single PCI-E slot for your GPU, full-sized ATX boards can offer 5-6 PCI-E slots of different sizes allowing you to connect a number of expansion cards with ease.
6. M.2 Slots and Storage
Just like the memory installed on your computer, you should also ensure that you can install high-speed SSD drives. Thankfully, almost all B450 motherboards include at least a single M.2 slot, which should be good enough for the average user. But, if you are a heavy-duty user, then you may want to get a B450 motherboard that offers 2 or 3 M.2 slots for high storage capacity while having excellent storage speeds.
7. Ports
Once you have finished your computer build, you would want to connect various external input and output devices like your mouse, keyboard, speakers, monitor, printer, webcam, and various other things. To connect all of these devices at once, it is quite important to have multiple ports like USB type A and type C, HDMI ports, audio ports, ethernet ports, and others. A few motherboards also offer wireless connectivity options like Wi-Fi and Bluetooth for ease of use.
8. BIOS
A great thing about motherboards is that their chipsets can be updated over time using BIOS updates. With a BIOS update, you can expect to get new features as well as better stability and performance out of your computer. Hence, it is quite important to go to your motherboard’s website and check if it regularly gets BIOS updates.
9. Warranty
Almost all of the B450 motherboards in the market include a 3-year warranty which is pretty good in most cases.
