Question No POST after upgrading some components ?

Mar 14, 2023
Windows 10 64-bit
Ryzen 7 5700X
ASUS ROG Strix X370-F Gaming
MSI Mech Radeon RX 6750 XT
EVGA 650W G+

G.skill Trident RGB 4x8 3200mhz
Samsung 960 Evo 250gb boot drive
WD Red 4tb HDD
PNY 120gb ssd

items in bold text are the upgrades installed today.
when I use the PSU tester the unit fan starts up, and my case lights turn on. When I connect the PSU to the Mobo only the standby power light comes on, no fan, no other lights. Front IO panel doesn’t light up and power doesn’t do anything. My HDMI monitor detects some connection but no signal.

I updated my bios to the latest stable build less than a week ago in preparation and had no problems beforehand. I did a CMOS reset with the battery out and still haven’t had success. I’m worried something happened to my Mobo connector port during installation but I can’t think of what.
