I have this motherboard:
http://www.supermicro.com/manuals/motherboard/X58/X8DTT.pdf

It has strange 20 pin adapter. I have some new atx psu's.
How could i make it so that the thing actually turns on and provides power to the cpu.
I tried running the rail VOLTAGES by copying the voltages and it would TURN on half the board.
Running it only with the molex turns on the other half?

Pls help. Is this a handshaking issue? Can it be circumvented or is it something on the board that I haven't activated like with pin connections. I am open to all suggestions that aren't "just buy another".Can you please keep this issue confined to one thread.  You now have 4 threads on the exact same issue.I keep getting the same answer on those. I changed the subject to my real newest question. I now set those as solved.http://www.jonnyguru.com/forums/showthread.php?t=12212
found it myself.

Ok so now the motherboard fully has power. It won't post though is it possible that the rails aren't supplying enough power?
or is something wrong?What is wrong? You are into something that is over your head.
Look here: (PHOTO of specs for HP 850 watt server supply)

This is from the spec of an HP power unit used for a HP server. It is not like any desktop PSU. It is a real brute. These are custom built for the companies that sell servers. They are not intended to be sold for general use on consumer desktops.

Not only will you have to get the boltholes and currents right, you will ha need  the proprietary circuits  to start and shut down the unit.

Or to put it another way, those who work with these things in an IT department would never attempt to 'hack' and standard PSU to work with such a BRUTAL motherboard. It requires a 800 +   watt PSU.

Thank you. Now I got it. Sorry!

I did get it to power on with the lower supply but I guess it holds out on me because of the design psu strength. I naturally thought that since it could not possible (no way in *censored*) use that much power for the 2 95W chips it would be fine.So then, would a:

 Dell Poweredge R410

for example, work with the system I set up? i.e. a 500w atx or does it necessarily need a redundant psu?

This question has been asked over and over again. Nobody reads anymore.
Do I need a server PSU to go with a server motherboard? If so what type?
Similar to these questions:
 
   Can I use tires  from my Chevrolet on my  on my John Deer tractor?
   If I donate my garden house to the local fire department, will they use it?
   Can a 40 year old women wear a training bra?
   Will my old Commodore 64 programs work on my new PC?
 
You can Google:
Dell Poweredge R410 power supply
And see the right answers.

Also, you can find:
http://www.dell.com/downloads/global/products/pedge/en/server-poweredge-r410-technical-guide-book.pdf
Which is the tech guide from Dell.
The correct power supply is about $110 from eTechNext.com or from Dell. But not Amazon and Newegg and stores that do consumer stuff. 
No, As I have said repeatedly you need the exact model of PSU designed for that board.  The Poweredge R410 uses a standard ATX pinout of PSU.Server motherboards are often made to fit in a short rack mount chassis. So the PSU has to be a odd SHAPE that fits inside the rack chassis.
The kind of thin is call 'relay rack' in the industry.  Standard size is 19 inch.
https://en.wikipedia.org/wiki/19-inch_rack

So, even if he  used a PC type PSU, it will not fit in the chassis. But the he  did not say what enclosure he was going to use. Bot using an enclosure will violate fire and safety
standards and will violate you home insurance policy.
Got it to work. Rewired a 1000w server psu and got windows 7 on it working like a breeze!
It was the mobo all along, it was broken. So it goes to show, you can diy almost anything!mrfresh - How did you end up rewiring the power supply? I am looking at doing the very same thing for my SuperMicro board, which appears to be the same board you were using at the start of the thread.

Currently trying to pull the wires out of the connector in order to re-position them.
