Upgrading MoBo, have a few questions

Posted by p3ib0l@reddit | buildapc | View on Reddit | 4 comments

Hi! After having some problems with my computer, I recently upgraded most of my old PC components (new PSU, CPU, GPU and RAM). Now everything is working fine. I was thinking on upgrading the MoBo, since I'm still using an ASUS Prime B-450 Plus, which I bought second hand in 2019 (I think it was first bought in 2018). I have some questions about compatibility and the installation process.
My first question is, will there be any compatibility issues between the case front panel connections and the MoBo? My case has two 3.0 USB connectors, and I have seen that this MoBo has a USB 3.2 Gen 1 header (u32g1_12), and even though I have been looking for information, I didn't really understand if it will work or if there could be any issues.
About the installation, I know that I have to update the BIOS before installing the CPU with the BIOS flashback using a USB, but I have never done that before. When I have the motherboard, to do the BIOS flashback thing I have to only connect the PSU with the Motherboard connector (24 pin?) and the CPU connector (8 pin?), both of which are connected directly to the MoBo, right? Do I have to do something else, other than connecting the USB and pressing the button once the PSU is connected to the MoBo?
Other than that, is there anything else I should be aware of? I built my old PC from scratch and also installed the new components now myself, so I think I'll manage the installation of the MoBo, watching again a couple of tutorials on the way. But I never switched a MoBo maintaining the same components, so I don't know if there's anything else to it, or if the computer will just work completely normal afterwards without any further action.

This is my current build:

Zero reason to upgrade your motherboard if it’s still working. It’ll have absolutely no performance difference. If your motherboard dies, get a new AM4 board.

p3ib0l@reddit (OP)

isn't a newer motherboard with newer chipset and better VRM, plus M.2 heatsinks, gonna make my system have better performance and longevity? I'm gonna swap the motherboard eventually anyway, because I had problems with the PC before, probably because of an old and not so good PSU, so even though the PC is working now, I still fear that the MoBo might not be in perfect state. That plus better VRM to keep the whole system cooler makes me want to swap it sooner rather than later, hoping that this will also help the rest of the components last longer.

Oh, and the new one would have 4.0 PCIE, which would also help my new GPU's performance

Yeah absolutely none of that matters. It’s going to have zero performance difference. You’re not even remotely close go maxing out the PCIE gen 3.0 slot with a B580. Save yourself the money and spend it later on something that will actually help performance.

USB 3.0 and 3.2 gen 1 are the same header.
