Where to plug in power SW on MSI motherboard

At this point, my advice to you would be a video guide on how to complete your build to avoid confusion and have a visual reference of where to put everything correctly.

There will be a small 2 pin cable coming from the power button. it conects to your motherboard via the front panel header (page 6 in the motherboard manual).

You wont' get a specific guide for the cables themselves, just where to plug them into the motherboard. That's because the cables are going to come from your case's front panel and no motherboard manufacturer knows what case you have.

That's what I was thinking, but wanted to verify before I tried to power on w/o the proper connecters all set and ruined something like the motherboard etc. Any insight into where these two should connect to on the motherboard?

M/B D-RGB 3-pin D-RGB FAN

Cable labeled Power SW goes to Power SW header. The rest of the cables your case has seem to be fan and RGB cables and they go elsewhere (not to front panel header).

Trying to get these last couple remaining cables connected before testing

Some cables (eg. HD activity light) have a right and wrong way for the two pin cables. Switch cables (power and reset) don't matter.
If you put them in wrong it won't damage anything - just turn the PC off and turn the cable around.

The two fans in the front of my case are not starting up when I power on the PC.

Am I missing plugging something into the motherboard? If yes, what am I missing?

Did you plug in the SATA cable coming from the front of the case, as the manual says to do? You've made no reference to a SATA cable, but this case has one.

You also make no reference to the USB 3.0 header coming from the case as well. Which means you're either leaving things out, the case is missing something, or you're not reading the manual, all of which are problems in slightly different ways.

I do not have a USB 3.0 cable. Now when I think of USB 3.0, I think of the USB cable that has blue on the end instead of white...I do not see any of those inside the case....

There should be fan headers on the motherboard. The case fans should be plugged into them.

There aren't necessarily fan headers from the fans that need to be plugged in to run the case stock. Like many case manufacturers, Phanteks gives their preinstalled fans their own controller, which is what the USB header is coming from. I believe your Eclipse P350X is similar, though I don't recall directly.

Ahh, yes I have the USB 3.0 connected. If I can figure out where that SATA connects to the motherboard I'll be golden

On my Phanteks P350X, the sata connector in the case connects to a sata connector on the power supply. There is an integrated controller in the case which controls the case lights. I assume that it works the same with your case and its RGB fans.

It could be bc I don't have my video card installed atm? I dis-assembled bc I couldn't get power up

Or the D-RGB FAN cable that I haven't connected yet.

Does the image assist at all here?

Not sure how to respond to that one. No idea why the BIOS updates would be better or worse, they all come from AMD for feature changes, and then tailored to each board by the manufacturer, in addition to bug fixes the manufacturer caused or noticed. Generally all B450 boards support 5000 series, just not out of the box. And a good number of the boards support CPU-less flashing. (Including the Aorus you picked out) You are missing quite a few features. A series has no overclocking, limited USB ports, you lose PCIe 4 on both graphics and storage, which might become a thing, and generally not as good a VRM layout. I see many B550 boards cheaper or around the same price as the two A520 boards you have listed, just not sure I understand. I would probably pick the Gigabyte, since it is a full ATX board (another oddity) and has heatsinks on both sets of VRMs rather than just the CPU power ones.

Still, taking a cost difference of twenty dollars to get one of the nicer B550 boards. That will likely pay off in the future with newer graphics cards.

You really shouldn't. Look for some B450 motherboards before you settle on A520.

You can use a rgb hub or splitters, be sure of the voltage that the rgb needs, for fans normally is 5v and for strips is 12v (not sure about that), the 5v header has 3 pins, the 12 v has four be sure to connecta that correctly otherwise you can fry something

Ok so i just fixed it, i had to prees a switch to kind of left control in the mobo

plz link to the fans you bought.

I have noticed that a lot of 450 MB's will not support the Ryzen 5 3400G. Why ?

Sure you meant B450? I believe its most, (but not all) B550's that dont support the 3400G. (or other 2nd-3rd gen iGPU's)
