Question New build won’t boot, no power indication

[Reel9898]

Hi. This is my second ever build so I’m still a noob.

I’ve tried everything in here https://gamesreq.com/troubleshootin...entifying-issues-with-psu-motherboard-or-cpu/

I’m building with the x870 ice, Ryzen 9 9950x cpu, Corsair h150i elite capellix aio, Corsair vengeance DDR5 6400 32gb (I have two 32gb sticks but trying to boot with one), Kingston kc3000 m.2. 1tb and Corsair RM1000x psu. No gpu as I’m waiting for 5000 series to release.

I’m getting nothing when trying to boot, no lights, no debug codes, no display. I’ve done everything on a grounded esd mat whilst wearing a wrist band. I’ve tried inside and outside the case. The standoffs are correct and nothing is touching the back of the motherboard when it’s in the case. I’ve reseated the cpu, no film on it anywhere. I’ve reset the cmos several times and tried the reset button on motherboard and Q-flash on the IO. Even tried a new cmos battery.

Currently plugged into motherboard are the 24 pin, 2x 8 pin atx (I’ve tried one), cpu fan header and hdmi.

I’ve tested my psu with a tester and all voltages are correct. I can’t try a different cpu or ram as I don’t have any but I would expect the leds to tell me if there was a fault with them. I’ve also tried letting it memory train for around 5 mins but there’s no sign of life.

Any help would be appreciated as right now it seems like the board is dead and I’ve already sent one back for the same reason. Any questions I’ll reply asap.

Same thing with previous board, makes me wonder if it's something simple missed like case power button connector not connected to the correct motherboard pins?

The cables used came with Corsair yeah? No other cables from a different psu in the mix?

It’s currently outside the case so I’m using the onboard power button and also trying the power pin short

Cables are original with new psu

Only other thing i can think of atm, besides being unlucky a second time with doa board, is checking modular power cables are fully plugged both ends.

Yeah I’ve tested each cable and tried every connection. But thank you. I’ve emailed support but it’s gigabyte sooooo.
