Hi, so I replaced my psu the other day and now no drive is being recognized by the UEFI boot menu. Before replacing it my computer was perfectly fine, but now nothing. I've gone through tons of forums trying to find an answer but I can't. So here's all I've tried, reinstalling windows 10 via USB, bootrec.exe, disk partitioning, and making sure the cables were well connected.
 
You said - you tried reinstalling windows. So did you reinstall or not?

If you want Windows Boot Manager in boot options, then windows has to be installed in UEFI mode.
You obviously reinstalled in legacy/csm modde.

Show screenshot from Disk Management to confirm that.
 

Do you see it in the BIOS? When changing the PSU the BIOS may have been reset; if so, then set it back the way it was before.

Alright. I'm done worrying about it now so I'm no longer looking for answers. I'm just going to sell the components I know work fine and get either and xps or Alienware. Thank you guys for the help.
