I put everything in my new computer together and went to push the power button and nooooo, it didn't turn on. So I started removing components and it will turn on inconsistently. Finally after removing my 2nd processor it starts everytime. I put the processor back in and it stopped working. I switched the processors (put the one i pulled out back into the cpu1 slot) and it doesnt matter which processor is in cpu1, it works as long as there isnt one in the cpu2.

Think it could be the mobo bad?

I've got an H8DCE and two http://www.newegg.com/Product/Product.asp?Item=N82E16819103573
 
you need a PSU with a 24pin plug, a 8pin plug, AND a 4 pin plug. that seasonic mention above is great. powerful and silent
 
That seasonic looks like it has the 8-pin EPS connector in the photos and 4 pin P4 style 12 volt connector, so you should be alright. Try booting with 1 cpu and flashing to the latest bios. H8DCE

Also, do you have atleast a stick of memory in each of the four bank sets?
 
try doing one stick for each cpu and see if it boots with both in.
 
it should boot without any memory in - just should spit out post errors. It wont even turn on at the moment with both procs in.
 
You'll just get beeps with no memory in, there's no way it will boot and give post errors. I'd try varying the number of sticks and there positions to determine it's not a bad stick of memory. If that doesn't work, it sounds like you may need to RMA the board unless Supermicro offers support, I don't know if they will as that is usually an OEM board.
 
Should the psu have 20-22 amps on the 12v rail?
them procs are very power hungry...
