    Default GIGABYTE GA-EP45-UD3P won't start up...Power Supply?

    Hi guys, I'm building a new computer and have had issues getting it to start. It'll make slight noises or flash a few lights when powering on but simply won't start. I've just attempted booting it up with motherboard, cpu, and memory and still nothing. Which leads me to believe that my power supply is to low-500W. I'm pretty sure the board needs at least 500w to boot up so I'm confused :/.

    -Antec Sonata III 500 Black 0.8mm cold rolled steel ATX Mid Tower Computer Case 500W Power Supply

    -GIGABYTE GA-EP45-UD3P LGA 775 Intel P45 ATX Intel Motherboard
    -Intel Core 2 Quad Q9650 3.0GHz 12MB L2 Cache LGA 775 95W Quad-Core Processor
    -Patriot Extreme Performance 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model PDC24G6400ELK
    [x2 for a total of 8GB of ram]

    Thanks for the help.

    500w should be plenty,have you tried with just one stick of ram?and make sure its in the correct slot

    If this worked, would it still be possible to add the other 3 through bios or something later? (Sorry I'm a bit new to this.)

    you can test each stick in slot one,that way youll know if you have a dead stick of ram if all your rams working then install it all and it must be something else,have you made sure your heatsinks propperly fitted? and do you have a manual to tell you which colour code ram slots to install them in?? on my board its the white slots but your board will be different
