I currently have an Asus B650E-F which from Sept 23 until a few days ago has been perfect, now on each shut down the bios flashback button is flashing causing the board to no longer boot without powering it down via PSU. Its a bit of a pain having to reach down and to the back of the pc everytime I want to start it up.

Needless to say Asus havent been the most helpfull so far so I'm thinking of getting a new board and wondered what people would recommend, paired with a 7950x3d and 64gb dominator 6000mhz ram and a RTX5080. Been looking at MSI Mag boards and there doesnt seem a huge price difference between a B850 and X870 chipset (£40 or so) so would I gain anything from upgrading the X870? I currently also have 3 m.2 drives installed which don't seem, to have eaten into the PCI-E lanes like my intel board at work has with 2 m.2 installed.

Intel 12th-14th gen will always eat the PCI-E lanes if you have a PCI-E 5.0 M.2 slot, because the CPUs don't have any spare PCI-E 5.0 lanes.

With Ryzen, the CPUs potentially support 2x PCI-E 5.0 M.2 drives, but only B850 is likely to use that because X870/X870E tend to use 4 of the CPUs 8 spare lanes for USB4. MSI often do things differently, so YMMV there.

If you don't care about USB4, also worth looking at X670E, since it usually avoids the lane sharing issues and there are some decently priced boards around.
 
Imo, you'd be better off replacing an M.2 with a higher capacity one to get down to just using 2, or sucking it up and using a SATA SSD than trying to spend a wedge on a board that properly supports 3x M.2's nicely without caveats.
 
After ASUS initially saying it was a likely PSU fault then changing their minds and saying the blinking flashback light was a bios fault they suggested trying biosflash back again, the board is now completely dead and wont boot at all just stuck on orange dram light :(

MSI MAG X870 TOMAHAWK WIFI is now ordered and will be with me on friday, and yet again will have to drain the bloody waterloop :(​

Managed to bring the board to life again leaving bios flashback runnign for hours, light was still flashing so presumed it must have worked, to my amazement I restarted it and it sprung into life, still have to switch it off at psu then back on and immediately hit the power button otherwise flashback light starts blinking again and wont boot, seems its not an uncommon issue with certain asus boards.

Been in touch with Amazon and they have accepted the return for a full refund so upgrading from B650 to X870 for free is pretty good
