I have built a computer before but it has been several years. A lot has changed since then. I couldn't find a prebuilt computer with the specs I wanted. So I got the components from Newegg. Assembled everything in the case, turned on the power supply. Nothing happened. Reseated the memory, CPU, video card, all the cables in the motherboard and PSU. Still no power. Ended up taking the motherboard out of the case and tried with the minimum amount of memory, etc. plugged in. The CPU fan LEDs, four LEDs on the front and three LEDs on the back of the motherboard lit up for maybe 1 – 2 seconds. That is all. Nothing more happened.
I thought it might be the power supply. Purchased a PSU tester. The following is the results of those tests with two different PSU since I thought I was getting bad readings from the first PSU. I purchased another one thinking that the first was bad. The second PSU had somewhat similar readings. So I tested an old one I already had. Far different readings than the two new ones.
1st PSU: MSI - MPG A850G
-12V 12.1
+12V2 12.7
5VSB L.L
PG 0ms
+5V 5.0
+12V1 12.3
+3.3V 3.3
2nd PSU: CORSAIR RMx Series RM850x
-12V 13.5
+12V2 12.5
5VSB L.L
PG 0ms
+5V 5.0
+12V1 12.0
+3.3V 3.3
3rd PSU: an old one
-12V 12.4
+12V2 L.L
5VSB 5.2
PG 260ms
+5V 5.2
+12V1 12.4
+3.3V 3.4
The remaining components:
CORSAIR 7000D AIRFLOW Full-Tower ATX PC Case
​
ASRock B650M Pro RS WiFi AM5 AMD B650 SATA 6Gb/s Micro ATX Motherboard
CORSAIR Vengeance RGB 192GB (4 x 48GB) 288-Pin PC RAM DDR5 5200
MSI Ventus GeForce RTX 3060
AMD Ryzen 9 7900X - Zen 4 12-Core 4.7 GHz - Socket AM5
Cooler Master Hyper 212 Halo Black CPU Air Cooler
SAMSUNG 990 PRO 2TB SSD, PCIe Gen4 M.2 2280
The free gift from Newegg: Patriot P400 Lite M.2 PCIe Gen 4 x4 1TB SSD, Solid State Drive
Is there something here that I am missing? Is the motherboard bad or is it the power supply or both? I am in a sort of time crunch because Newegg's return policy. I didn't think that this would still be a problem nearly 3 weeks after getting everything together.
I appreciate any and all help.

I haven't used a PS tester. Does it check voltage with all connections? If yes, then voltages are fine. If not, then you must use a voltmeter with everything connected, since the issue might only show up when the load is attached to the power supply.

Do you have any extra parts available for testing some of these items?
I notice something unusual on the mobo support page. The CPU is running BIOS 1.18, which seems to be the default BIOS. Almost everything on the QVL is showing BIOS 1.28 or newer.
If this were a RAM problem, you’d expect a debug light or speaker sound. The quick power-up and shutdown might be difficult to troubleshoot on your end.
Do you have a reliable local shop nearby?

When using the PS tester, its the only thing attached to the cables. I'm not sure how much load it provides.
I don't have any other spares other than the old power supply, unless I pull apart an old computer that I stole the hard drives from. I attempted to update the latest BIOS version but I don't think it worked. The lights don't tell me much of anything and if there is a speaker on the board, never heard a thing. I contacted Asrock and all I got was a message that their voice mailbox was full and never heard back at all when I submitted a support ticket. There is a computer repair store here. I'll have to call them.
