First off, will this PSU power this motherboard, i7 920 CPU (with fan plugged in), and 6GB triple channel 1866mhz RAM, and this graphics card (using two 6 pin to 4 pin connectors to make this card compatible with my PSU)? ONLY these things? Nothing else is plugged in.
It comes down to these possibilities: Bad motherboard, bad RAM, voltage on RAM not compatible, short in the tower's power button switch, weak PSU, non compatible PSU (has to be 12V?)
This is a long post containing three hours of trouble shooting condensed into these paragraphs. I hope I can be able to help anyone else out with similar problems. Please read it all before giving a suggestion because I have tried many suggestions already.

I have tried the suggested problems thread and nothing there worked. Here's what I think. I have a Coolmax 480W power supply thats about 5 years old. I think it's too weak to even turn on my system but the only things connected to it are my motherboard with the Intel Core i7 920 processor in it along with the stock fan, and my HD 4870 1GB GDDR5 PCI x16 graphics card. The graphics card came with two, 6 to 4 pin adapters. This is good because my old PSU doesn't have any 6 pin power on it. I hook the two six pins into the graphics card, each pin has two, 4 pin adapters; that makes four, 4 pin adapters. I plug all four up to my power supply, plug in my 20+4 pin connector to the motherboard and thats it, nothing else's power is plugged in. I push the power button on my tower and it doesn't turn on.
Is the PSU too weak to even power it on? I have unplugged EVERYTHING else in an attempt to get it to power on. This is a complete custom build. The case has a wire runs from the power button to the inside of the case. From there, I connect the pin to the motherboard according to a chart. The motherboard manual says "Power BTN" goes in pin 4 we will say for example. But the wire has two holes, not one. Other wires are easy to attach. Another example, motherboard says "Power LED +" goes in pin 1, good, it only takes up one pin so i stick it in. "Power LED -" goes in pin 2, good, it also only takes up one pin. Next, "Power BTN" goes in pin 3, but the actual connector takes up two pins. It fits, but on two pins, and I think one is a ground. I have tried plugging that "Power BTN" in the orange connector on the motherboard in any way possible and still no luck.
My motherboard supports triple channel RAM up to 2000mhz (OC) per stick. I purchased 1866mhz ram (not OC). It says it supports 1866 mhz (OC). Does this mean my natural speed of 1866mhz is not supported, only slower speeds that CAN be pushed to 1866mhz?
Also, I have tried all three sticks of RAM one by one in every slot trying to power on my computer. How do I tell of the voltage is too high? I mean, if my RAM is not compatible, will my computer not start AT ALL? Can I turn on my computer with absolutely no RAM? I have tried and even with no RAM it still does not work.
Here's the weird thing. I tried to power it up for an hour last night, it wouldn't so I hit the net for some help. Looked back behind me after about 20 minutes and the motherboard was on. How do I know? It has a little debug display that shows numbers on it that glows red. It's a simple two-digit display. I wish it showed a number but it didn't, it just showed sort of a half of a "0". Before I touched anything, I hit the power button to try to turn it off, it would not respond. I hit it a few more times and nothing. I then unplugged the power, then plugged it back in and hit the power button. Nothing happened.
I'm getting a brand new 750W modular power supply in five days (yay for ordering Tuesday nights; 3 day shipping becomes 6 days for Newegg). Maybe that will help. Five days is kind of long to wait. This whole experience is turning out to be a nightmare. Tigerdirect charged me twice on accident for my i7 processor causing my bank account to reach -$178.
