My motherboard has two spots to connect a 24 pin power

Hey guys, I picked up a dual socket mother board that has two spots to connect the 24 pin power supply.

I can not find any info on this and can not find any info on the motherboard.

One 24 pin socket sticks up like a normal mobo and the other one is sideways. Points out along the axis of the PCB.

This is a "Server" mobo I think, my question is, does it matter what socket I plug my PSU into? or can I even use just one? do I need to use two?

I think you can just use one. Try the "normal" first and see if it boots. If not, try using the other socket or the other 24pin.

You want cringe?

Ok! Here we go:
i7 3770 - it's not THAT bad
HP Mobo - here's where it gets even worse
6 Gb DDR3
GT 630 - yes, GT
case from the HP prebuilt
same as the PSU
LG 1360x768p - man, I want to cry
Drevo Blademaster Pro (Cherry MX Red) - I'm still waiting for my preorder:(
Logitech G305 - 90g ?
Logitech G533 - I love wireless stuff

If they are normal 24 pins, its probably wanting one per socket

I spent $2500 on building my PC and all i do with it is play no games atm & watch anime at 1080p(finally) watch YT and write essays...

Sounds like a server board that has the ability for redundant power supplies not sure though if both are needed good chance that it is not needed but you would need to provide board specs to confirm

Okay,

     So, took the heat sinks off figured I should replace what ever thermal past was in there, who knows how old.

The board is a dual socket with two Operon 280's in it. 

The board has one vertical 20+4 connector and one vertical 8 pin (CPU?) socket.

The horizontal 20+4 connector sicks out the side of the board perpendicular to and just behind the last PCI slot, how in the world would you even plug in a connector there, unless it's in a non desktop type case. at any rate, the 2nd horizontal power connector has "AUX" printed on the mobo next to it.

I only have one 20+4 power supply that seems to fit, the +2 connector on my other PSU seems to have different shaped plugs and don't fit.

Will take some photos when I can.

Photos of the 2nd power connector.

I found that the board is an Arima HDAMA and the "Long" PCI slots are PCI-X not PCI express.

I was able to turn on the mobo with a single connector plugged into the the "normal" vertical 20+4 connector using the on board power button

Screen just showed the Arima logo but nothing else. Same thing when I plugged a single connector into the horizontal "Aux" connector, just the Arima logo.

Server motherboards take a very long time to POST. Give it 5 or even 10 solid minutes and see if it continues to boot.

Okay with an Antec 650 Watt PSU plugged into the vertical power connector the board will sit at the Arima logo for an hour, or at least that's when I gave up and turned the system off.  To be thorough I plugged the PSU into the other "AUX" connector, same result.

 

Maybe the 650 watt PSU is not enough power?

 

The system is two dual core Opteron 280s

                       four 80mm fans (one for each CPU and two for case)

                       eight sticks of 2GB EEC ram

                       one IDE HDD

 

I don't think that this would be to much of a draw for the above PSU? Either way, I'm sure the board does not take an hour to post.
