So what? So per stick performance will be lower. Why does that matter? You are not using them individually, you use all of them at once. I doubt that’s something to worry about too much. RAM amount makes certain things possible. The per stick performance?.. Who cares?.. Or am I mistaken somewhere? Plus DDR5 speeds are great anyway. But, OK, that’s apparently not something I know too much about, I 'll have to refresh my knowledge apparently.
I gave my thoughts on this, and hope @rangeros386 can build his/her PC.
I have no intention to start a discussion with someone who seems to be disagreeing on anything that is discussed. And not just in this thread…
Go outside, and have a walk 
I am not arguing. I did not know about this. I am just asking questions. Which of course doesn’t mean you should answer them if you don’t feel like it. I’ll look into this.
It is more a DDR5 thing then DDR4, but at the same time, your DDR4 at 3200 isn’t exactly super fast compared to where DDR4 speeds have peaked. Hence that’s likely why you are all OK at 3200 speed.
I mean you can get 4400+ speed DDR4 sticks, but try running that with 4 sticks and I doubt any system would boot. DDR5 has now pushed this even more so.
Yes it is worse with 4, since it adds higher latency. Would you notice it with stuff like Blender, etc, no, not really. Can it be measured in lower FPS with games, you bet it can. It does then of course depend on other factors as to how much it matters, but all that aside, at the end of the day, if you are going for high performance, 2 sticks of RAM are better then 4.

It’s not just for stability. You’ll want matched sets to take advantage of dual and quad channel memory setups.

A couple of thoughts.
Seasonic are a pretty good PSU brand, but having said that, the one you got listed is basically as low as they go. I’d maybe look more at the Seasonic G12 GM ones or ideally something from their Focus series.
That aside, I’m really only left with a minor issue/question over the CPU and GPU.
Now the CPU is fine, it will perform well, has 12 cores and all that, my possible issue is exactly how useful that will be outside of full on CPU rendering. You see its actually 2 lots of 6 cores, so unless you are really pushing more then 6 cores, you don’t gain much. In fact you may be hurt a little, depending on how well the system/software can manage processes between those two 6 core units.
The moment processing starts to cross between the units, things can slow down. As such, short of really heavy multi-core workloads (in which case you are really better off with the top-end 16 core CPU), then one may well be better off with something like the 7700X. Which gets you a full 8 core single unit.
Which in some ways then leads to my GPU issue, in that the Gigabyte Eagle is pretty much the lowest model of GPU you can get. Meaning I’d be tempted to drop the CPU to the 7700X (or the new 9700X if its about the same price, but at this stage it likely won’t be) and take those savings and use them to get a better brand/model version of the 4060 Ti.
Alright, thank you! What do you mean by a better brand of the 4060 Ti? Should I get something like the MSI 4060 Ti? I thought that MSI, ASUS, and Gigabyte were among the best manufacturers, and I didn’t think there were noticeable performance differences between them.
I just checked the offerings in my country and compared them with my budget, and I can choose one of these cards:
INNO3D NVIDIA RTX 4060 Ti 16GB N406T2-16D6-178055N
ASUS RTX4060Ti DUAL-RTX4060TI-016G
GIGABYTE nVidia GeForce RTX 4060 Ti 16GB 128bit GV-N406TWF2OC-16GD
ASUS nVidia DUAL-RTX4060TI-A16G
Gigabyte RTX 4060 Ti GAMING OC 16GB (GV-N406TGAMING OC-16GD)
MSI nVidia RTX 4060 Ti 16GB RTX 4060 Ti GAMING X 16G
I have one more question: I noticed a big price difference between the Box and Tray processors. As far as I understand, the only difference is that the Tray doesn’t come in a box. I was planning to buy the Tray processor because it’s much cheaper. Do you think that’s okay?
One more question! 
Do you think it’s okay to go with the Thermalright Burst Assassin 66.17 CFM CPU Cooler instead of the THERMALRIGHT Peerless Assassin 120 SE, considering that I’m getting the 7700X processor?
It’s not so much the manufactures, but the model. I mean just like I wouldn’t get a Gigabyte Eagle, I wouldn’t get a MSI Ventus either. They are both at the bottom of their product stack. So while performance may well be more or less the same, the lower down you go, the hotter they tend to get (cheaper heatsink/fans, etc), which in turn means louder fans and possible shorter life. They will last the warranty, but doesn’t mean you will get 5+ years from them.
At the same time, that doesn’t mean you have to go ‘elite’, like a ASUS ROG Strix. Yes, they are a darn nice and well made card, but for the most part, not worth the extra cost.
From that list of GPU’s, it would be worth looking for specific reviews, but the Gigabyte Gaming OC should be fairly good, followed up by the ASUS Dual or the MSI Gaming X.
I think the other difference is warranty. From my understanding, tray CPU’s are sold to system interrogators, meaning if something goes wrong, you must deal with them, Intel or AMD won’t talk to you.
Compared to retail, where you can always go back to Intel or AMD if need be. So if the place you are buying from is a good business, expected to be around for years to come and easy to deal with should something go wrong, then a Tray CPU is fine.
If possible I’d likely stick with the Peerless Assassin 120 SE. It’s a pretty good cooler for what should be a fairly good price and there’s no such thing as too much CPU cooling.
Two small ones in addition to the other comments:
- Try to add a second SSD or HD to the rig, and keep your data on the 2nd. Just to be on the safe side. Keep backups too!
- Don’t skimp on the PSU. Try to go for at least 800-850W just to have a little overhead.
Power supply is important.
In the case of cheap ones, it is hard to believe that they provide the output indicated in the manual.
Usually, you just don’t recognize the problem because you are using a power supply with a higher output than you need. 
The problem I had recently was also a power problem.
The HDD kept behaving strangely, and it was solved by using a single power line.

No, I mean - sure - a really cheap power supply is not the best idea. However this has been the trend for a very long time now - everyone says you should not save on a power supply and I just think a lot of sellers and manufacturers are simply taking advantage of it with premium products and even if not that a lot of people overpay for a PSU just out of irrational fear. It’s really difficult to know in some cases if a premium product will be any better than just a decent regular PSU as long as it’s not the cheapest off brand model ordered from Aliexpress.
The fear of damaging other components is also… well… maybe not completely irrational, but maybe often over exaggerated. It doesn’t necessarily damage other components on failure. I had a PSU failure after 11 years of usage(!) It wasn’t cheap, some Corsair model(I don’t remember) and it just failed. I was lucky to have access to another PC with a matching PSU to diagnose the issue and just bought a new PSU in a local shop in a couple of hours and that was that. Nothing terrible happened. I know it’s 1 datapoint so it probably doesn’t mean much, but still…
I think it’s not a bad idea to use a PSU that is rated to something more than you need, because as you say, if I am using something with higher output than I need I don’t see any problems. But then again that also has limits in my opinion. In many cases “what I need” might not be that much.
Let’s try to guess what the system in question might need:
RTX 4060 Ti - 160W
Ryzen 9 7900X - 170W
RAM - ~3W(guess) x 2 = 6W let’s round it up to 10W(which is probably not possible) so no one complains
SSD - ~10W max, let’s add 5W just because
So that’s like 355W, let’s add 100W for the motherboard itself(which is more than it needs) and let’s add a couple of storage SSDs, now that’s 485W. 
So… I don’t know… Maybe you can have some LED strips and some fans that draw a lot of power, but the system should run with 500W power supply. 600W power supply should be perfectly OK. It’s fine to get a more powerful one, but that’s… more than needed. I see nothing wrong with getting a 750W PSU if that’s what one’s heart desires, but it’s a bit of a waste of money. It’s not much though, so I think it’s fine either way and it’s always nice to add another GPU in the future, so I guess it makes some sense. I just don’t think one needs an expensive PSU. ~60 euros would be what I would personally spend on it.

It’s fairly rare that a PSU goes bad, and takes out a bunch of other bits of hardware along the way. Usually, the most damage occurs when a power supply has crapped out just enough so that you don’t immediately notice it, providing power to all your components anemically and unevenly. Over time, it can wear your entire computer down.
Fortunately, that’s usually pretty easy to spot when it starts happening.

Yeah, that’s when happens when you have a good PSU fail. When a bad one fails, it kills the motherboard and CPU, in my experience. You make a compelling argument to get an expensive PSU
What specific PSU would you buy for yourself for the chosen components?

I wouldn’t buy the specified components, and since my computer has 7 SSDs and 128 GB of RAM, my power requirements are very different anyway. But generally, I would never again skimp on a PSU, after losing a CPU and motherboard (plus several SSDs) that way

There is no need for the average user to use an excessively expensive power supply.
However, it is also correct that you have to spend more than a certain cost.
As someone else mentioned, as the usage time increases, the efficiency of the power supply decreases, and even if unstable power is supplied, it is not easy for users to notice.
