Advice Needed to Choice A620 vs B650

[taneryurttas]

Hello,

I am in the process of building a gaming PC and have finalized some of the components:

CPU: Ryzen 5 7500F

GPU: RTX 4060 Ti


My goal is to choose a motherboard that provides stability, does not have overheating issues, and allows for future upgrades, such as upgrading the CPU or GPU. During my research, I came across two main chipset options:

1. A620

More affordable

Does not support overclocking

No PCIe 5.0 support


2. B650

More expensive

Supports overclocking

Has PCIe 5.0 support


Here are my questions:

1. Is it necessary to perform a small overclock on the Ryzen 5 7500F, or are the stock speeds sufficient?


2. In the future, if I decide to upgrade the GPU, will the lack of PCIe 5.0 support significantly affect performance?


3. Are A620 motherboards sufficient in terms of performance and stability, or is it worth investing more in a B650 motherboard?



I need to manage my budget carefully, as the exchange rate in my country is high (1 to 35), which makes the prices significantly higher compared to international markets.

I would greatly appreciate your advice and recommendations regarding motherboard selection.

Thank you in advance!

If the cost is high a budget A620 could be a good solution. B650 has more flexibility and also has OC support. If it was me and I was thinking about tomorrow I would go with B650. Good luck A620 are not bad as a platform if indeed the money is that tight, You won't miss anything unless you want a ton of M2 drives.

You're doing it all wrong. Choosing chipsets is one thing, but they aren't related to what you want here.

You're doing it all wrong.

The way he is doing it is not "all wrong" at all. And sorry, but simply telling someone they are "all wrong" without providing any suggestions for what you consider is right is hardly helpful. In fact, that is "all wrong".

The fact is, there are many ways to go about choosing components for a new build and his way is, more or less, the way I choose my components for all my own new builds. I decide first on the CPU I want, then I research motherboards that support it. I also typically choose a brand of motherboards early in the process too. I like, for example, Gigabyte so I will look to see if they make what I want first. That said, I am not locked into a brand and will go with ASUS, ASRock, or MSI if they have a board that meets my needs better. I also look for a board that my budget will currently allow that has the most current features to ensure the longest "future proofing". This is because when I build a computer for me, I expect it to support me, and evolve with me, for at least 5 years.

@taneryurttas - your way, thus far, is just fine but does require some adjustments. You need to set a budget. We have no reference to go on when you simply say you need to "manage" it. If a tight budget is a top priority, then the choice seems clear and you should look at the A620 boards. But if the budget allows, and you are looking for more features and longer "future proofing", the B560 may be the better choice. But note not all B560 or A620 boards are the same. There are budget, entry level as well as higher end models with either chipset.

Note that a quality case and quality PSU form the foundation for a quality computer that can provide years of quality service and plenty of evolving upgrade options. I personally like Fractal Design cases and Seasonic PSUs.

And speaking of cases, the case determines the size motherboard it will support. I typically recommend a quality "mid" tower case as they will typically support all sizes of motherboards except, maybe EATX - but almost no one needs an EATX board, or a "full" tower case either. Just note if opt for a smaller case, you may be limited to a micro-ATX motherboard, and a graphics card that is physically smaller too.

Do NOT try to trim the budget with a cheap power supply. You would not buy a brand new Porsche then fill it with generic fuel from the corner Tobacco and Bait shop. And wait until you have selected all your components before choosing the PSU so you know first, what your power requirements will be. I prefer Gold certified PSUs. I do not recommend Platinum or Titanium unless you just happen to find one on sale that has been greatly discounted.

does not have overheating issues

This really does not make sense. Motherboards overheating is not really an issue. The issue is the user ensuring case cooling is capable and properly setup by the user to provide an adequate supply of clean, cool air flowing through the case.

That said, the B650 supports more powerful processors so it can support a larger maximum TDP. But again, it is the responsibility of the case - and ultimately the user to ensure an adequate supply of cool air flow.

To answer your questions:

1. No, it is not necessary to overclock. The Ryzen 5 7500F at its default settings is a fine processor as is.
2. No, the lack of PCIe 5.0 support will not "affect" performance but it may limit your future purchasing options. If my plan was to ensure the best "future proofing" (and it always does), I definitely would go for the board that supports the latest technologies, in this case, PCIe 5.0, even if I was only planning on using a PCIe 4.0 card - for now. In 2 or 3 years, I might want to upgrade my graphics and that would be much easier (and cheaper) if I did not need to upgrade my motherboard (or PSU) at the same time.
3. Both boards are very comparable in term of performance. While the board matters, of much greater importance is the CPU, GPU, and RAM, and drives too.

As a side note, the currency "exchange rate" does not matter. If the price is £120 British pounds or ₫3,821,400 Vietnamese Dong, that is still (at least today) $150 US dollars. So what matters is simply the local price - which may be higher or even lower in your part of the world.

his questions were separate from the preface, i was just commenting on that part. He clearly can research and he did, i just pointed out a flaw on his reasoning that could impact the questions he put there, needs further research, if he was more queries he can put them as an answer.

He asked for advice, you gave him none. You just said he was "all wrong" without providing any suggestion as to what might be right. To be of any help, you could have provided some advice that did "relate" to his questions. That's all I am saying on this. Moving on, waiting for OP to reply.

I would go for B650 for just being more future-proof. A620 is so entry-level chipset that I'd recommend it only for the extreme budget solutions.

Manual overclocking a Ryzen is practically useless, just use PBO (and curve optimizer) and let it do its magic. The lack of PCIe 5.0 wouldn't most likely be a bottleneck, even with a 4090, PCIe 3.0 x16 is only marginally slower, and even with 3.0 x8/2.0 x16 the performance isn't that bad.

NVIDIA GeForce RTX 4090 PCI-Express Scaling

The new NVIDIA GeForce RTX 4090 is a graphics card powerhouse, but what happens when you run it on a PCI-Express 4.0 x8 bus? In our mini-review we've also tested various PCI-Express 3.0, 2.0 and 1.1 configs to get a feel for how FPS scales with bandwidth.

well i upgraded my pc i went with b650 and not a620
1.better support for better cpu in the future
2.better stability
3.the price diffrents is not big - i guss its about 20-30 $ more in the usa
4.vrm and usb and all that things ...

i think for the price you should go with b650
but a620 its also nice with this cpu (7500f)
