I completed assembly comprising the A520M-ITX/AC motherboard, Ryzen 5 3600 CPU, 16 GB Corsair Vengeance LPX memory, Samsung 970 EVO NVME, Asus RTX 2070 GPU and Corsair RM 750 PSU. On first boot I don't see the BIOS screen. The GPU's power indicator light shows power, fans are operational, but no display. I double checked the CPU power cable and it is well seated both in the PSU and motherboard. I removed and re-seated the GPU also. I was wary of a possible incompatibility between the Ryzen 5 3600 and the A520 chipset but the CPU QVL shows compatibility at all BIOS levels, albeit with a red asterisk beside the CPU name, and that red asterisk is not explained anywhere I could find. I do not have an internal speaker so I cannot hear any beep codes. At this point I do not know how to diagnose further, and would greatly appreciate advice/guidance. |

The "*" is just to denote that those CPU variants do not have an iGPU. Try with a single stick of RAM in slot B1 and make sure to clear CMOS. Leave the system powered for at least 5mins, sometimes memory training can take a while on first startup with a new CPU. -------------

| Thank you very much. I learned about the asterisk this morning looking at the QVL once more. If the QVL is to be believed the Ryzen 5 3600 should be supported with any BIOS revision. I replaced the GPU with a known working unit and behavior did not change. LEDs on the GPUs show power, but no output results. plugged a testing module into the PSU motherboard connector to verify motherboard power, then re-seated the motherboard connector just to be sure. I will next remove one stick and leave it on for 5+ minutes. Again, my thanks for your guidance. |

Unfortunately, I never got any video output. I left it on for over an hour, reset CMOS beforehand, and I'm still without video. I don't look forward to filling out a support ticket, but that's the only option I have. Given my prior experience with Support, it will take 8-10 exchanges before the Support technician concedes that I have an issue with RMA potential. If that's the buyin, so be it. |
