Hi,
I'm coming out of a tech coma where after my last build I stopped paying attention to what was going on with parts and such for 2+ years and just want to make sure I am not missing something with this build. Im not 100% on the PSU and want to make sure I understand that I need to do a BIOS update with my board in order to use my CPU. Any other general advice or just confirmation that this will function properly together would be appreciated.


CPU: Ryzen 9 3900x

Case: Fractal Design Meshify 2 Gray Mid Tower (comes with 3 fans and looks like it has good air flow so might not need additional cooling)

GPU: MSI Radeon RX 6900 XT (yuk on that price T-T)

Mobo: ASUS AMD AM4 ROG Strix X570-E Gaming (listed as being good with the Ryzen 9 in my quick research)

Memory: G.SKILL TridentZ RGB Series 32GB DDR4 3200

PSU: Corsair RM750x 750W (I think this one has the right connectors, cant seem to find one with lower wattage that has the ones I need)

Am I missing anything obvious? Any conflicts or incompatibilities?
Appreciate any feed back, just dont 100% trust myself rn.

I am assuming this is a gaming rig? If so, an R7 5800x would be a better solution. It would require a bios update, and Asus's flashback utility isn't very good. I would suggest Gigabyte instead. Unless you really have a need for all PCI-E lanes to be gen 4 PCI-E a B550 would be a better choice, with regards to better rear I/O. 750w might be a bit low, with that combination, under heavy loads. I would do something like this.

Personally this is what I would do for a build. You were missing a boot drive in the build so I added one.

I saw that video, and considering it was only a couple times he had issues with it, I do not see it as an endemic issue with ASUS's BIOS flashback. I suspect that the board in question had something wrong with it preventing the flash from working properly rather than the flash being the problems itself.
