System Won't Boot

Wrong again, if you have really looked at a power connector the top edges are cut at a angle the bottom is square, you cant plug it in wrong and a missing pin will not stop you from plugging something in, if you had a pin where there is no hole that would stop you but that is not the case here!! Its a extra ground that some power supplys have and some dont!

So either way it isn't the problem?

Really sounds like a short or a bad P/S or board, I would really go over the case for a short, make sure theres no stand off where theres no hole! If you know somebody that has a P/S you could use just to test that would help choosing between the board and P/S

If you bothered to look you would have noticed the the locking tabs on the outside of the connector itself where the clip on the plug locks it down. :rolleyes:

What does that have to do with anything! You said the missing pin was so you cant plug it in wrong. Do you drink alot?

That you are! The #18 pin is an optional 5v feed that is no longer needed on the newer model boards. http://pinouts.ru/Power/atxpower_pinout.shtml

If the retaining clip breaks off for some reason you can always refer to the missing pin when going to plug in the main connector. The molex connectors for drives are the ones with beveled corners for a one way for the most part. Sorry no drinking allowed here! :eek: or at http://www.vlug.org/pipermail/discuss/2006-February/020463.html :D

So long story short it nots the power connector causing the problem.

It is either a too low of an output from the supply itself or a related board problem. Unless the main power connector was miswired at the factory which is a little rare the output isn't strong enough to meet the minimum power demand. One quick way to find out if the supply is the problem would be to try one that is known to be a working atx supply. If the system fails to start you know the supply has nothing to do with it.

Just threw in a brand new power supply but no luck :(

Sounds like a bad board there. A friend had me go over a new build recently when even the replacement board was "doa". A bad bios EProm chip will do that as well as a defective main chipset. I can only say rma the board fast since it should be still under the vendor's return policy unless you have to ship direct to the manufacturer. At least you will have a good supply to work with.
