Not sure if the motherboard or power supply unit is faulty.
I built a fresh system after my previous one failed. The hardware includes a Ryzen 7 5700X, an ASUS TUF B550 Plus, Gigabyte AORUS 3060, 12GB NVMe SSD, 16GB PCIe 3600, and a WD Black 500GB NVMe SSD. I also have two additional SSDs and an external SATA cable for devices not in the system. They didn’t appear in my BIOS boot sequence, and scanning in Windows failed. I’ve used a USB to SATA adapter to inspect the internal drives and HDDs, which did recognize them. I thought trying different SATA ports on the motherboard might help. When I removed my GPU (the 3060, which is quite large and blocks the SATA connectors), I heard a noise. I checked both the motherboard and GPU for damage, found none. After swapping the power cables and reinstalling the GPU, the system wouldn’t power on. I went through standard troubleshooting steps—re-seating RAM, booting with a single drive, resetting CMOS, discharging the CMOS battery, and disconnecting everything except the CPU and GPU. Still no success. The issue seems linked to the PSU; when I flipped its power switch, the corner LEDs and Ethernet LED also lit up, suggesting something was malfunctioning. I’m unsure whether a new motherboard or PSU is needed, but it’s definitely not ideal.
Do you have another PSU available to test your components? If yes, attempt it and observe if the problem resolves. You might also use a PSU tester to verify correct power output. If this doesn't fix the issue, your motherboard could be faulty—consider testing it with different CPUs, RAM, and see if the performance changes.
I wish I had the additional parts needed. I can cover a bigger MMO and extra PSU, but that’s about it. I’d rather skip buying more stuff. I’m also thinking about getting a PSU tester to eliminate the possibility of a faulty PSU and possibly get a refund for the motherboard.
