Will be using my existing dell 24 inch widescreen digital ultrasharp monitor in 1900x1200 as mentioned.

I finished putting together my system today. It took a bit longer than I thought, but I wanted to take my time and make sure I got it right. When I went to power up my system, all that happens is that the light on the "SupremeFXII" soundcard comes on and the green light on the Mobo lights up. Nothing else. No fans, no BIOS, no screen appears, nothing. I tried removing 1 stick of ram, and no dice. This is my very first build, so I am pretty much a noob at this sort of thing. I can tell you that I did use the provided Standoffs for the Mobo and plugged in the 8 pin and 24 pin power supply adapters to the Mobo as well. I am not sure what to do at this point. Is there a problem with having a SATA drive when you first boot up? I am grasping at straws here. Does anyone have some ideas that might help me? Thanks for your input.

try 1 gig sticks on the ram get some 800's and make sure they on the asus list of ram, I am not familiar with the board so some one else may chime in here soon. Double check all connections.

Is the psu power switch on the back switched on?

The PSU switch on the back is switched on. Nothing happens when I push the power button on the Antec case, although it is hooked up to the power button relay on the Asus mobo.

You mean the ASUS Q-Connector Kit?

Remove that. You can power it on by shorting the PWRSW pins with the tip of a ball pen. See manual for the whereabout.

Is not your ram, even if ram is deffected, system should still power on. It seems u connected Power Switch 2 cables on the wrong pins on the motherboard ( look through mobo manual). Had this problem before. Power Cable PSU provided me didnt work. Try a different cable, if still no dice, u might received a deffected power supply. Also make sure Video Card or sound card metal holder aint touching motherboard edge. U can post a very closeup picture of the inside of your rig to see if everything is connected correctly. I power switch is not connected on the right pins. Man, you should gone with Nvidia 8800 gt for 17 dollars more, more faster card.

Well, thanks for the suggestions. I ended up testing the power supply as suggested on PC Power & Cooling's website, and it looks like it is a bad power supply. Tested the GPU in my old computer and it works fine. Hopefully the Mobo is ok but I really have no way of knowing at this point. To rick, I went with the HD3870 because I plan on going Crossfire and it gives me a wider range of Mobos to choose from. If I was going with one GPU I would have went with an 8800GT.
