I just bought a MSI PRO PRO B550-VC AM4 for an UnRaid/PLEX Server I am building. I have 1 GPU NVIDIA and 2 SAS PCIE cards for my 12 hotswap bays. My problem is the PC will not post to BIOS. I am after this thread gets posted I am removing the CPU and making sure no bent pins, redo the heatsink goooooo and try to reboot and see if it posts. Will the 2 SAS adapter cards work with this setup? Below are pics of my setup. 1 1050Ti NVIDIA for transcoding, 2 SAS PCIE cards for my 12 hotswap bays. UnRaid OS runs from USB. Ideas??
Update:
Yes I have 64GB of ram, just pulled it before pic.

Am i spotting a green-label Corsair Builder Series CX750 with 3 years warranty from circa 2012? Yeah, no way you can be sure this is still good, the electrolytic capacitors will have deteriorated by now. The RAM is one thing of course, but this PSU should be replaced with a new high-quality and high-efficiency PSU, see my Guide: How to find a good PSU.

Thanks. Yes, p/s is old. That's the next purchase. This has in the past been a hand me down rig. I am working on a 15 bay JBOD I am building to add to this also.

Try without all the drives connected. Try with a different PSU which is known good, not too old and preferably within its warranty period, and of decent quality.

For this many drives, you can't mess around with a low-end PSU model where the warranty has run out eight years ago, you need something newer and higher-quality.
