Will the M1-ATX run the Intel D945GCLF2 Board?

It appears that the Motherboard may have an extra connector.

Thanks in advance!

Can I take power from the 12V rail of this power supply to connect to the P4-12V connector on my new motherboard? I don't want to get a new PSU just for the extra connector.

I guess I should ask. Will 90 Watts be enough to power a D201GLY2A mother board and a SATA hard drive? If it isn't big enough I guess I will just have to get an M2-ATX.

I have an issue with my M1-ATX just like the one that has been reported for M2-ATX as well:

I want my PC to hibernate on Acc loss but whenever I cut Acc power to the M1-ATX using the ignition key the PC does a hard reset, starts to reboot and finally gets killed by the M1-ATX hard power-off timer. The odd thing is that it only happens if I use the key. If I leave the key in Acc position and instead manually disconnect the Acc wire to the PSU the PC hibernates just fine.

I discussed this with an electronics engineer and we came to the conclusion that this probably happens because the acc bus in the car might be briefly connected to ground when turning the key. I would need something faster than a multimeter to find out.

Anyhow: I put a rectifier diode (100V, 3A) inline with the Acc input to the PSU and the problems are gone.
