Hey Guys,

I built a new system with the following parts.

CPU: AMD Ryzen 9 3900X 3.8 GHz 12-Core Processor
MB: ASRock B550 Steel Legend ATX AM4 Motherboard (Bios V2.10)
Ram: G.Skill 32GB TridentZ Neo
HD: 4 X Seagate 6 TB 3.5" 7200RPM Internal Hard Drive
HD: 1 X Samsung 970 EVO Plus 2 TB M.2-2280 NVME Solid State Drive
PSU: Corsair SF600
Case: Rosewill RSV-R4000U 4U

As soon as I try and boot from USB Unraid, Fedora, Ubuntu The machine immediately resets.
On the mother board I don't have the 4 pin PSU connected plugged in but i'm told I don't need it.

Any Ideas?

Be safe plug the connector in, always utilize all the power connections!
