First of all - welcome to BC !

 

 

Verified VGA with known good

 

Can you expand on what you mean by this ?  Having eventually found a listing for the back panel connectors it appears there is no on-board video so you only have whatever video card you have connected as video output.

 

If you tried a different card on this mobo that would suggest a card problem; if you tried the card in a different comuter and it produced a display this would suggest a mobo problem.

I've Tried A known Good Video Card In This Machine - Still No Display, I;m Up In The Air As Far As RMA'ing the MoBo Or Purchasing A New CPU To Rule That Out What I was Hoping To Get From these Post Is The Likely Hood Of DOA MoBo Or CPU Damaged by PSU Failure 

 

I've Heard that CPU Failure Is Unlikely But Am Unsure

Can you explain the nature of the PSU failure? Surge? Capacitor melt?

 

Also, how does the MoBo not post? Any beeps? If no beeps, try removing RAM and checking on-board speaker.  Almost wonder if you knocked a M-connector when replacing your PSU.

What you have just done is a reasonable indicator that your problems lies with the mobo or CPU, but is not conclusive. Have you tried the Radeon R7 in another computer ?  If the card works there then it is definitely not the card.

 

If I read your OP correctly you kept the old CPU but bought a new mobo. Do you still have the old mobo ?  Since you have bread boarded the components it would not be too difficult to see if that mobo works with your CPU. If it does, then the problem is with your new mobo.

 

If it doesn't you have the problem that, since your old mobo may be fried, this doesn't prove anything either way. In which case the only thing to do is to see if you can access a computer using the same CPU and see if your CPU works in that.

 

This sort of fault finding is truly a PITA because you are dealing with three components which are essentially non-repairable and substitution is about the only effective technique if you don't have a test lab handy. I would, like you, be inclined to suspect the mobo since CPUs are reasonably robust  and fairly heavily protected but they can fail, or be blown up.
