Need help in figuring out why motherboard won’t turn on

I just purchased all my pc parts and am attempting to build my first pc, I’m following this tutorial on YouTube (https://youtu.be/BL4DCEp7blY?si=vkqDJn_UW8mB9kJC) by linus tech tips and have reached the part where they boot up bios to test if everything is working, I have connected my power supply (MAG A65OBN) and their cables (I believe all in  the right slots) into the motherboard (MSI B65OM gaming plus wifi AMD Ryzen) and connected the hdmi cable from my monitor into the graphics card. The video mentions using a screwdriver to turn on the motherboard by pressing down on a specific pin which I’m not too sure about which one. However, after connecting everything there’s no display on the monitor. Also, when powering on the supply supply, the motherboard doesn’t glow or anything, so I’ll unable to know if it’s properly powered. Any help would be appreciated!

For the second pic, you need both CPU Power inputs filled (modern PSUs should have two 8-Pin CPU (EPS) cables).

Also make sure your GPU is powered via PCI power cables.

I just looked it up and the MAG A650BN is not compatible with your motherboard / CPU. It only has one 8-Pin CPU cable

 

Did you do a PCPartPicker build of your system?

If yes please share the link. If not you will want to do that before proceeding further.

it can be directly from your screwdriver! we didn't do this in Pentium 4 when it was new! you have to put it in pc case, then try again, there is a tiny cables, you have to put them correctly in the case, for shut down and restart and usb,..

I used this list PCPartPicker list:

There is a note at the bottom of your parts list:

 

Note: The MSI B650M GAMING PLUS WIFI Micro ATX AM5 Motherboard has an additional 8-pin EPS power connector but the MSI MAG A650BN 650 W 80+ Bronze Certified ATX Power Supply does not have any available. This connector is used to supply additional current. While the system will likely still run without it, higher current demands or extreme overclocking may require it.

 

The "Will likely still run" used to be true but as the second connector become more common that has shifted to "will possibly still run" as motherboard manufactures implement safeguards to prevent damage to systems with insufficient power.

 

Even if it did post, running it with only one connector is a bad idea and risks damaging your CPU.

 

You will probably want to return it and get one with two EFS connectors. There is little reason to go with less than 80+ Gold efficiency these days either.

 

Also of note.

 

The GPU in your picture is this one:

Not the one listed in your parts list:

If you bought the XFX deliberately it makes little difference. If you ordered the Sapphire and received an XFX however, you should be very worried about counterfeit / defective merchandise.

 

Double checking that your RAM is seated properly would be a good idea too.

 

And yes the screwdriver method is risky at the best of times.
