Looking for advice about motherboards
I'm thinking about consolidating my 4x GPU rigs into 7 or 8 GPU rigs.
1) Is either of these better than the other? ASUS PRIME H270-PLUS -or- MSI Z270-A PRO
2) How reliable are the m.2 to pci-e adapters? Are there some that are better than others?
I haven't had an issue with any type of m2 adapter; they have been reliable for me so long as you power them.
ASUS PRIME H270-PLUS -or- MSI Z270-A PRO are both good mobos; you will need to do an Internet bios update with the H270; but it is the easiest bios update I've ever done.
Also you will have problems using ribbon risers with either. Use powered usb risers instead.
main consideration for 7+ gpu rigs is the PSU / PSUs used
