Glad to hear you got it up and running Thumbs Up

For future reference, I highly recommend you do not run any system without a CPU cooler. While it should be possible with thermal throttling and other safety features it causes an extreme amount of heat, well beyond the operating heat the components were designed for. Heat like this can radically reduce the lifespan of effected components. Even just sitting the heatsink on top of the CPU without fastening it down is better than doing this.

I am writing this from the new PC! All good now. The problem was the "MSI RX 580 gaming X 4g" GPU that was DOA. BTW, for future reference:
* A glowing GPU doesnt not mean a functioning one
* It is possible to POST without attaching the heatsink, except this mobo will give a "CPU Fan Error" message at startup

Am just curious if these AM4 motherboards would prevent a POST due to lack of a heatsink.


I do not believe it will give you ANY beeps w/o a heatsink/fan.

Having a heatsink/fan attached is one of the first checks a motherboard/cpu/bios does.

Bought and tried a new PSU (Corsair VS650) No luck. So I assumed it must be the mobo.
Therefore, I sent the ASRock AB350 Pro4 for RMA and replaced it with another. Still no luck.
Bought an ASUS Prime b350 mobo. No luck.
Only CPU and GPU remains. New ones will arrive tomorrow. Will keep you updated.

It absolutely does matter Shocked You should never connect the PCIe 8 pin power lead to the CPU 8 pin connector. It doesn't always damage the board but it certainly can.

I have to clarify this for anyone reading this thread. There is a reason they are labeled PCIe and CPU 12v not just generically 8pin 12v. They have different pinouts and are even keyed differently.



Back on topic. I take it you have had no luck with any of the suggestions here? If you have not already, take it all apart completely and put it back together again carefully. Quite often that will sort things out.
