I bought some used items from ebay to attempt a build of a small server. The parts I chose were:
Intel x5570's
this lga1366 mobo:

an evga 500w 80+ Bronze
and some RANDOM matched 1333mhz ecc ddr3 ram

The psu wasn't to the supplied by the manufacturer however I was able to rig it with the correct voltages (not ideal but its a good psu so, whatever...). However I put in a speaker to the JSPKR pins and I only hear the fans amplified, (even when i remove all the ram) , I think. Furthermore no vga input is registered on my monitor. Do I have to start with one cpu and then try to add another after it configures? I am really at a loss. Thank you in advance for looking at my post and answering. I'm so confused! The way this server is you have 2 CPUs, so a 500 watt is ALMOST running like 2 x 250 watt supplies. If any wiring is wrong you could have destroyed the motherboard and components. Additionally the parts are not new. Bought used off of ebay and so you might be dealing with bad part(s).The power is sufficient and having removed one cpu it beeps quickly. (so its posting an error, now) I found out it was that it wasn't detecting memory. I had mine put in the black sockets now I'm trying the blue.
And now it stopped posting again...Having horrible luck! I'd start by getting the correct power supply for this instead of trying to rig up a NORMAL pc power supply to function as a server supply.I think the cpu isn't getting HOT....The heat sinks aren't heating up...Could we ignore the psu thing? Before i hooked it up it certainly did not turn on. and it was beeping ofr a couple seconds so the motherboard was fine, that might be the new problem (cpu not heating up/ starting?) Have patience wit me I've only made one other computer.The CPU will not get hot unless it is under load so not heating up is not a sign that it is not working. Your issue here is using a non-standard motherboard with consumer parts. My advice is to sell or return that motherboard and replace it with a standard ATX board with standard PSU connections, you aren't going to get a case to fit that board either.

That said, for anything beyond a basic home server, you really shouldn't be building it yourself with consumer parts, buying a server premade or building it exclusively with server grade parts is almost always a better option.I know that but i need a high computing machine for my COMPUTATIONS. Are x5570's consumer chips on a server board? The board supports them, me thinks? it said series 5500 and 5600 chips. so the motherboard is the issue? also my chips are lga 1366 so...what else could I use for these Xeons?You have a server chip and a server board but you are trying to use a consumer PSU to power it all, this is your issue. With a PSU like that you should be using a regular ATX form factor board with those CPUs rather than that proprietary Supermicro one. As far as I can tell, that board is designed for supermicro's high density rackmount servers where you would power multiple boards from a single, high powered 12v PSU and then rely on the board to do voltage regulation, it is not designed for a standard desktop PC.
