Could be missing the power_ok signal the A4000 is looking for.

Indeed, it should. I have one on my 4000 as well. Is Pin 8 of the ATX plug side of the adapter connected to ground?

Check this link

^^ looks like someone else is having this issue too (unsolved) using the same adapter.

And here he is on EAB.

His issue was a short somewhere. But, other users chimed in about newer PSUs needing a SENSE signal on the 3.3v line, elsewise they won't power up.
