No power through pc build. Not sure what steps i should take next.

I absolutely hate the fact that I just had this whole post typed out and accidentally backed out. So here we go again:
I have built 3 gaming PCs previously.
I am currently working on my wife's build.
The part list is:
CPU: intel i5-12600kf
Mb: colorfire b760m-meow d5 purple
Ram: Crucial Pro 32GB (2x16GB) DDR5 RAM Kit 6000MHz
Power supply: CORSAIR RM750e
Case: segotep Memphis s meow ninja purple
I had the whole build built. I can no get any power.
I have reseated all connections. I have tried shorting the switch pins. I double checked the motherboard manual to ensure i had the right pins. I triple checked I actually turned on the power supply. I've removed the GPU (i know no integrated graphics on the CPU, I was just looking for lights, fans, anything), nothing. The system is acting like I never even plugged it into the wall.
I have never had issues beyond this in a build and I have no clue what my next step is. I feel like at this point it's safe to assume I either have a dead power supply or a dead motherboard but I'm not sure the next step besides just buying new ones to know for sure. Any recommendations would be appreciated.
(I would post photos i took of everything, but reddit is telling me this forum won't let me attach)

If literally nothing happens when you short the pwr_btn pins, then it's either a dead motherboard, a dead psu, psu switch is off, bad power cable, or there's no power in that outlet

Yeah, I addressed that near the end. At which point, what should be the next step? What do i test first? What do I buy first? Etc.

Well, i'd test the psu first, disconnect it from everything in the pc all motherboard connections, gpu, drives, literally everything (to prevent potential dapage)
Take a piece of wire, or bend a paperclip or something, and short the green wire to a black wire (any black, they're all ground connections), there's one right next to it
If the PSU turns on, you get power on the 5 and 12V rails (you can test with a multimeter, easiest testing a molex connector, red is 5V, yellow js 12V, black wires are ground)
If the psu gives you all the right voltages (you can google "atx psu pinout" to know which wire should give what voltage, like red=5, yellow=12, orange=3.3 etc.)
If all is good, then i'd probably rma the motherboard

Hey, just looking back on my posts today and realized I never said thanks. I appreciate your advice!

no problem man, what ended up being the issue?
IDidAOopsy@reddit (OP)
The 4 pin on the MB had a bad connection. So it was shorting everything when it was plugged in. We just swapped the MB

huh, probably a busted VRM, it's a pretty rare occurance on modern boards, especially with consumer CPUs, but i guess you got unlucky, glad u solved it though, glhf
