I fully agree that AMD should have and usually does respond immediately. I would suggest another phone call tomorrow during AMD Biz hours and hopefully they can get this resolved quickly.
FWIW, all CPU/APU/GPUs are tested just before they are boxed and are known to be good when shipped. It takes a LOT of shipping abuse to damage a CPU/APU/GPU based on the special packaging used and double boxing. I mention this because your new APU may not actually be the issue when all is said and done. It's extremely rare for a new processor to actually be bad. Damage during installation or use are the two biggest issues - if in fact there is really an issue with the APU.
As far as your mobo, it does in fact support the A10-5800K if you have the correct BIOS installed. See the link below for the required BIOS. If you're mobo is new, it may or may not have the correct BIOS to support the A10-5800K. If it does not then this would need to be installed before the mobo will recognise your CPU properly. This *might* cause the system not to boot or it might boot but give an error message like" Unknown processor". It depends on the mobo maker and how the BIOS is written.
If you are using a single DIMM RAM module, you may need to have it installed in a specific RAM slot per your mobo manual.
The most common reason for no boot is wiring issues. Your PSU has a 20+4 cabling arangement so both of these will need to be plugged into the 24 pin mobo socket. All additional 12v power cable sockets on the GPU card will also need power. There are a few exceptions, but generally all 12v sockets on a GPU card need 12v power.
Improper seating of the CPU, RAM or video cards is the next most common issue followed by video out port/cabling issues. Shorting of the mobo to the PC case is fairly common but you tested outside of the PC case, so that should not be an issue. You may have already checked these issues in your troubleshooting but it's easy to overlook something when frustrated... Been there, done that!
Obviously if you were testing the mobo out of the case on a piece of cardboard, you'd need to have jumpered the pwr-on circuit to get the system to power up or you'd still have no boot, unless your cables were long enough to reach with the mobo out of the case.
Technical ignorance is NOT a destiny it is a choice. Do your homework so that you can make technically informed decisions and not be duped by advertising hype or mis-information stated as fact when its not.
