I kind of doubt it's the caps as they look fine and rarely go bad on late Asus s478 boards.
In my experience BIOS (chip) issues like mentioned if the board powers on, shorted mosfet/mosfets in the CPU VRM circuit if it dosn't.
If the boards powers on and you have already replaced/reflashed the BIOS then keep the board powered on for a few hours. If it's the caps they might be persuaded to start working enough to let the board post.
Other things to try.
Another PSU like mentioned, especially if the board dosn't power on.
Other memory even if the memory used is known good.
Another video card.
Getting a POST-code card to see if there are any codes that could indicate where the issue is.
I think it's just some of the black OST caps on his board, those have a nasty tendency of looking great and being pretty 50/50 on actual capacitance. Agreed to rule everything else out before a recap.
