External testing with fans running but no visuals or post, need more power?

Hey you wonderful people,

I've seen this question asked before and gone through the checklist suggested on other posts on troubleshooting a no post beep, no BIOS problem, but think mine might be different. I am very new to PCs, building my first one as this is posted, but I have seen some answers regarding this problem that suggested being "power starved" and wonder if that is my issue.
Here is my build:
Motherboard - Gigabyte 970A-DS3P for AMD Socket AM3+
Processor - AMD FX Black Edition 3.5GHz 95W Six-core
RAM - G.SKILL Ripjaws X Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600
GPU - EVGA 02G-P4-3765-KR GeForce GTX 760 2GB 256-bit GDDR5 PCI Express 3.0 SLI Support Dual Superclocked
HDD - Western Digital WD10EZEX 1TB 7200 RPM 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive
And finally the potential trouble maker
PSU - CORSAIR CXM series CX500M 500W ATX12V v2.3 SLI Ready CrossFire Ready 80 PLUS BRONZE Certified Modular Active PFC Power Supply

So with just the GPU, CPU, stock fan, both RAM sticks, and the mini speaker installed, booting it up gets the fans going immediately and lights up a mouse and keyboard if I have them plugged in, but no splash on my monitor and no beep. Any suggestions as to what my problem might be?

  1. Not the power supply, unless it is broken.

    You have a minimum system.
    In that case you go by the video card requirements.

    The 760 calls for a 500watt.
    A good 450watt can run that card.
  2. Try 1 stick of memory, and try all the slots.
  3. Best answer
    Are your motherboard bios is updated to the latest?

    what are your processor model/type?

    example: some mobo don't support vishera (FX-x3xx) out of box, it need the mobo bios to be updated to the latest
