I have built several gamming computers, one with Asus and had good luck. What I do have is a power supply checker that I got from Tiger Direct that I use alot. To me a 450 watt PS sounds a little small . Sounds like it cant regulate the voltage, expecially the 5 volts. I have a master power supply (650 watts) that will hook up to any board or hard drive. I try it when I have this kind of problem. The only thing I dont like about Asus is that they have so many pins, so I would double check the pin settings.
Did the power supply come with the case.. If it did, change it. I have never had any luck with those. I really think they use 2nd hand ones for kits. Just my opinion GOOD LUCK
If you don't already have a case speaker hooked up to the board, you might want to connect one since there isn't an on board speaker and you will not hear error beeps otherwise.
Also, if you have another non-phenom AM2 processor handy you should really update the BIOS to latest release. Many late model Phenoms will not work on motherboards that have earlier BIOS releases and you will not be able to post. You should then choose "Set Optimized Defaults" and save the bios without any changes then shut down (not reset). When you power on again it should post and you should be able to get into the BIOS.
A third thing you can try (after you get a case speaker hooked up) is using a cheap pair of ddr2-6400 RAM to get the board to post so you can get into BIOS and change the voltage to the correct settings for your RAM if it requires a higher voltage than the bios expects.
Answer me this. You're case is an Antec tower? The motherboard is the Asus P4P800 SE ? Is this correct?
If you have you're manual you can see what goes where on the board for front panel connector page. 2-31. (This diagram shows you how to connect the front mic & speaker).
To connect the Antec's front USB ports plug the case USB front connectors onto USB56 & USB78 shown on page. 2-30. Most case wires are already set within their USB connectors & the Antec's front USB connector should fit right on the mother board's pin's.
