PC turns on, but no post

Hi, I recently purchased a Ryzen 2700x to go inside the new PC that I am building. After getting everything put together, I've found that the PC turns on just fine, including all lights/fans even on the GPU, but I get no POST at all. I also have a motherboard speaker installed that gives me no beeps when the PC is started. After some testing, I think I've ruled out my RAM sticks as they work in another system. I think I've also ruled out my GPU as I've tried more than one to no avail. I'm on my second motherboard and from what I can tell it isn't the issue. I've also tried resetting CMOS by jumping and removing the battery.


At this point I think I've narrowed it down to either the PSU or the CPU. For the PSU, I know about the paper clip test so I know a way to test that. I'm just kind of stuck on the CPU. Aside from sticking it inside a different PC to see if it works (I only have LGA sockets to work with besides this current B450 board) is there anything I can test or try to see if the CPU is what's causing me troubles? I know of breadboarding, but I'm worried about breaking my motherboard and I unsure of how it would tell if the CPU is not working.


Any advice or insight would be greatly appreciated, I'm really hoping I don't have to RMA the chip as I don't think I have a way to package it safely.
