Hello. I just got my ASUS B250 Mining expert mobo and it seems DOA. I just wanted to test the POST so first I installed the Core i3 gen 7, 4g if RAM. I connected the PSU to the 24 pin slot A and the 8 pin CPU slot. And I plugged in the CPU fan. I turned on the PSU and nothing, no fans spin, no video, nothing. For a POST I expect both the PSU and CPU fans to spin and get the BIOS to display on the screen. But nothing happens. I tried jumping the BIOS reset and still got nothing. I tested the PSU and it is fine. I even tried a different PSU that is working and is used on Ant S3 and still nothing. I created a RMA with ASUS to send it in for servicing. But before I do that I thought I would reach out and check if I am missing something, like is there a power on/off jumper I am missing or something else? This is not my first build either but my first ASUS B250. Please let me know if I am missing something. Thanks much!
I had the same experience. However, when I inserted video card into PCI-E x16 slot the mobo started.
