I saw the MSI MAG A850GL PCIE5 fully modular psu, and it is priced at a fairly low 89.99 at us.msi.com. I don't know if it can support my system as my friend says it is too weak for the RX7900XTX. Can you guys confirm this, and should i get this psu? I also have an option of the 4070 Ti SUPER; can you confirm if it works with my build (if i replace the rx7900xtx due to financial reasons)?
