self made computer wont turn on

Specs: N/A
Im a first time computer builder so i decided to build the exact model as the one in PC Gamers fall 2010 special issue (ill list the parts below). When i pushed the power button for the first time, the LEDs in the case fans turned on for a split second and it turned off. There were no sparks or smoke coming from the motherboard, so its not fried. I then unplugged all the connections and reseated certain parts, but every time I press the power button, a small click can be heard in the power supply and nothing happens. The LEDS in the fans never turned on again, but there are 2 blue LEDs on the motherboard signifying that the DDR is in 2 phase power mode so im assuming thats a good sign. I have a hunch that I got a faulty power supply but im not entirely sure. Please help!

CPU: AMD Phenom II x4 965 Black Edition
Ram: Corsair XMS3 DDR3 4GB (2 sticks of 2 GB)
Cooler: Thermaltake Frio
Motherboard: MSI 890FXA
Videocard: Radeon HD 5870 Eyefinity 6 edition 2GB GDDR5
Hard Drive: Western Digital Caviar Black 1TB
Optical Drive: Lite-on 24X DVD Writer
Soundcard: Sound Blaster X-Fi Titanium
Power Supply: XFX Black Edition 750 Watt
Case: Thermaltake Armor A90

Stupid question - did you benchtest the hardware BEFORE you put it in the case??

No, i didnt. I havent done any of this before so I didnt realize that was an option. The thing is, when i press the power button, none of the drives start spinning. the only thing that turns on are the leds on the motherboard that i mentioned. I read somewhere that it can be an issue with the powersupply, but the one i have is pretty reliable so i was doubtful on that. But i guess anythings possible

It may be the power supply, but it may be something else. That's why it's so important to benchtest 1st. Obviously it would be stupid to put non-working hardware in the case. But since you didn't test it, you have no idea if you have defective hardware or you did something wrong when installing it. The 2nd sentence in the link I posted says it all:

"If you take the time to bench test your build prior to full assembly you will save yourself hordes of time in troubleshooting a faulty component."

I know you copied the specs from a magazine, but here's a crtique of your build:

- cases with a bottom mounted power supply are a poor choice. If you want to know why, read this:

- high priced CPU cooler was unnecessary & can be loud

- while I'm sure the MSI board is a good one, you could have gotten an equally good board for about 1/2 the price

- was the sound card really necessary? I'm sure the onboard sound would have been sufficient

- power supply should be a good one. It's actually a Seasonic unit & it's "Jonny Guru" recommended. Of course, that doesn't mean much if you got a dud.

I would definitely try booting up with all drives disconnected and only 1 stick of RAM. Try different slots for the RAM as well. Do you have a cheaper video card you could try-one that uses less power ?

thanks for the critique mickliq, ill keep that stuff in mind. And no kx5m2g, i dont. Is there any way i can test the power supply to see if its working? because if it is working, shouldnt the drives start spinning and the fans, which are connected straight to the power supply, start up? and what does that click mean inside the power supply? i figured it was like a safety or something but i dont know
