GA-J1900N-D2H no display

[abes]

Hoping someone can help as I am really scratching my head with this one.

I am trying to get a GA-J1900N-D2H motherboard to work and am having real problems getting anything to display.

I am using a Morex 557 case bundled with a silent integrated Pico-PSU 80W internal power supply and external 60W 12V AC Adapter, a Crucial CT51264BF160B 4gb memory stick and WD Blue HDD.

When I put this all together and switch on the power the case light comes on, I can hear the hard drive spin up but I get no signals at all from either the VGA or HDMI ports not even a post. I have tested the VGA on multiple monitors and HDMI on multiple TV's, I have tested the ram in my laptop and I have tested all the pin out voltages on the PSU after shorting out the appropriate pins.

I thought the motherboard I had was DOA so I ordered another one but still get the same. I have tried to remove the ram and HDD and everything else I can, leaving just the 24 and 4 pin power cables and the power LED and Power switch jumpers but still I get nothing.

When I power everything on and plug a lan cable in I get lights on my router when I press the power switch so I am sure the motherboard has power but I cannot get any sort of display signal.

Is there anyway I can diagnose what is going wrong? The case I have does not have a speaker so I cannot get beep codes?
Does a fan need to be connected to either of the jumpers to get the board to boot?

A similar motherboard, Asus J1900I-C, lists power supply minimum requirements in its downloadable manual. Recommended minimum is 350 watts. You don't seem to have anything close to the minimum power required.

Connected a 250w power supply which should be more than enough to power this board, also connected a fan to each fan connectors and still the same. I give up going to send both boards back. I had heard the BIOS on these boards were a bit buggy but thought I would give them the benefit of doubt, slightly regretting that decision and the wasted effort and time. Going to get an ASRock board instead.

Just in case anyone else has this issue bought an ASRock Q1900-ITX. Plugged it in, all worked first time.
