Another motherboard installation, but it's not starting up.
Another motherboard installation, but it's not starting up.
For reference, my setup includes the NR200P MAX case, the 7800X3D and an ASUS B650E-i motherboard with compatible RAM. I copied a highly rated build from PCPartPicker, which gives me confidence it should work. I assembled everything a month ago, using a guide for the case. When I tried to boot, the QLED screen lit up instantly along with some RGB effects, and the fans started and stopped normally—no BIOS errors or noise. Initially, I tried flashing the BIOS, but that didn’t help. I then replaced the RAM, but it failed again, so I bought a new motherboard, which also didn’t work. I returned the CPU and tried a different PSU, but nothing changed. A local shop last week told me the motherboard is defective. Could this be because I accidentally got two faulty boards with the same issue, or are the PSU or cables the problem? I’m planning to build again with a third board this time, just in case.
I believe it’s more likely to encounter two faulty motherboards than a failing PSU or cables damaging the board. Unless you made a mistake with the cables or something similar. There’s an easy method to eliminate bad PSUs or cables—swap them out or purchase a new one. The cost of the PSU is typically much lower than the price of a motherboard. Let me know if this helps.
Sawa has the right point. It’s more likely you received two faulty mobos from a poor batch with comparable issues than your PSU being the problem. Particularly if the testing shop confirmed there was a defect. If you’re handling a replacement or refund, trying again for the board isn’t a waste of time. This isn’t a 90s PC build, and those slow BIOS launches are a thing of the past. Also, this doesn’t solve the op’s concern.
if it's a modular PSU and cables used form another PSU, you can fry your mainboard, SSD's and GPU..
I mentioned it could take as long as 15 minutes. Important points are that MSi AMD motherboards might need up to 30 minutes to show a BIOS screen. This answers the question you asked. Many users become frustrated when their PC doesn't display anything on the screen right after building, leading them to return items. They waste time troubleshooting or sending things back. Try staying positive instead of giving up.
