B550 pro4 not posting

   Hi!

I have just received a new B550 pro4 and I can't get it to post, I have it with :
-Ryzen 5 5600X
-2x16 GB DDR4 3200 (https://www.newegg.ca/team-32gb-288-pin-ddr4-sdram/p/N82E16820331618?Item=N82E16820331618)
-My old GTX 1070ti

I have both CPU and DRAM led open, no sound coming from the speaker, no image showing up on the screen.

I tried with the RAM I use in my other desktop and it doesn't work either. I've also tried with only 1 in A2 slot without success.

The GPU led opens but the fan close after 1s . I can't even turn it off holding the power button, I have to switch the PSU off.

Anyone have an idea ?

Thanks,

	For this CPU, the BIOS version should be 1.20 or higher, the BIOS version is written on a small sticker on the chip itself Disconenct all cables and test the board outside the chassis, sometimes one of the metal contacts of the IO shield, goes IN the port, instead of the outside. Check the pins on the CPU, if you put it in the wrong way, 4 pins will be bent. If this fails, use the customer support form, and provide the details https://event.asrock.com/tsd.asp When using Gmail., check your spam folder for replies
	Kind Regards

	This sadly ( or happily ) was a stupid mistake. I forgot the 12 pin ATX power on the mobo... Thanks for the help! Hopefully someone else can fall on this and not spend 4h trying to figure it out ?��

	I have the same issue. It will start to power on and then it will just stop. It has powered on completely once but it will not do it again. I have removed the hard drive, video card and tried both sticks of ram in slot a2. I have pulled the board out of the case to make sure it is not shorting out somehow but still no luck. I don't get any beep codes or anything. Here is what I am using. AMD Ryzen 5 500GT Crucial P3 Plus 2TB PCIe 4.0 NVMe M.2 2x32GB Corsair Vengeance LPX DDR4 3200 Rosewill CMG5 1000W Power Supply I am at a complete loss....

	Well it seems you must put the Power Supply in eco mode and all will be right in the world....it is working as it should once I turned eco mode "on". Not sure why but its working.
