I began with a different motherboard than the one I have now. I initially used the Asus ROG Strix B550F Gaming. Recently, I upgraded to a new PC case (Hyte Y60) and moved all my parts from the old case (Corsair 4000D Airflow) to the new one. When I tried to check if it powered on, nothing happened—no fans spinning, no lights on the board, just a single click from the power supply. I verified all connections carefully, even unplugging and replugging them. I also used a different power supply and cables, but the issue persisted. My GPU and RAM worked fine in another system, so I’m not sure if my CPU is the problem.
Later, I swapped out my motherboard for the current MSI B550 Gaming Plus model, but the same issue continued. I tested with another power supply and cables on the new board, yet it didn’t work. I plan to test my CPU in a friend’s rig tomorrow, but until then, anyone have any suggestions about what might be wrong with my PC?
I’d assemble everything outside your case (the mobo box works fine), and test it that way. It seems like a brief summary to me. If it doesn’t power on, try using just the bare minimum—just the mobo, no CPU, cooler, fans, AIO, RAM, etc. It won’t post, but should still show some activity. Then add each component one by one. Also, skip the obvious fixes like changing the wall socket.
As mentioned here, test results should be checked separately. There could be issues with certain models. Could you explain why you changed from a Corsair 4000D to a Chinese brand without a name? You know motherboards can be swapped, though MSI is a solid option. Or perhaps you didn’t connect the power cable to the motherboard or power supply unit if it’s modular.
They aren’t exactly what they seem—they belong to IBuyPower, which might sound questionable at first. But the build quality is actually quite solid. There are plenty of reviews available, noting strong airflow and an appealing appearance. I was looking for a slightly different style while still fitting my 360mm AIO on top, something I couldn’t achieve with my 4000D model. The phrase “You do realize motherboards are transferable” wasn’t clear to me. My decision to replace the old motherboard came from the belief it was damaged beyond repair, and I wasn’t planning on keeping it long-term. I don’t like MSI much because they’ve had two GPUs fail in quick succession across different generations. This MSI board was just the most affordable option I found locally for a temporary setup. I’m thinking about getting an Asus ROG Crosshair VIII Hero soon. I confirmed all power connections and component links in my post, and I’ll run a POST test outside the case. If it’s a quick issue, maybe just bending metal to avoid contact would work—or should I swap the case for a new one? Thanks for your advice!
I’ll definitely attempt a POST test outside the case. It would have been good to note that I tried a different socket on another breaker too. Thanks for the guidance!
It looks like the issue is likely resolved quickly. Both Asus and MSI seem compatible with the Corsair case, so we focused on that.
I’m not sure if the MSI board functions properly with the Corsair case. I purchased the MSI board after moving everything into a Hyte case, and it’s only been in that case so far. I think it should work fine since it’s brand new (or at least I hope it will). If I can get a post from outside the case, I’ll revert to my Asus board temporarily and reinstall everything inside the Corsair case while I handle the RMA for the current unit. Luckily, I ordered through Amazon, so returns should be smooth.
Discovered the issue—I was connecting two 8-pin power cables into the adapter, but switched to one 8-pin to 8x2 pin cable and everything worked fine.
