PC not booting. Please help.

[TheJedi]

 

I built a PC this morning. Parts are:

 

Ryzen 9 7900x
Asus Strix X670e-a gaming wifi
2 x 16GB DDR5 @ 5200MHZ
700W PSU (Not my build so I don't know the exact model but I can confirm that it does work as it worked fine in the system it was powering before.)
Corsair H100i 240mm
WD SN850x 1TB
GTX 1050 ti.

I'm sure i've connected everything. The motherboard lights turn on when I switch on the PSU but it doesn't actually turn on. I just get nothing. No Mobo LEDs, no fans. 

Going to take the mobo out of the case and test later. 

But what else could I try?

Did you correctly connect the case's power button?  Try jumping the power with a screwdriver on the motherboard.

Okay, I'll try that. 

Will It matter not having the cooler on it?

Put the cooler on. If it works, put in ram in slot A2 and B2 on the motherboard.

What psu? If you cant identify then take a picture of its wattage table

 

Hook the board to a psu and put in only the cpu, yes put the cooler on incase it starts

 

If it doesnt start wiggle the 24 pin cause sometimes that likes to be sensitive and make the board not turn on in certain positions i guess? Idk what word to describe that properly

 

If it still doesnt start just rma and get a replacement
