New setup not turning on - possibly psu issue

Hey guys, recently got my new setup all put together but when I try to power it up nothing happens.

CPU: Intel i5 4670
MoBo: Gigabyte GA-H87-D3H
GPU: sapphire amd radeon hd 6870
PSU: dx-ps500w

The PSU is fairly old, has to be a good 4 or 5 years, I moved it over from my previous system hoping it would hold up but I'm thinking it's probably the issue. Also it only has a 4 pin connector for the CPU power where as the MoBo has an 8 pin. I've read that the 4 pin can still work in the 8 pin slot as long as the CPU is getting sufficient power.

I was just wondering if anyone here had any thoughts, suggestions, or knew of anything I could do to test what the problem is before I just go pick up a new PSU.

  1. got the 4 pin in the right end of the 8 pin connector?

    have you tried taking the graphics card out and running the video from the onboard?

    The 4 pin will only fit into one side on the 8 pin slot, and I have tried without the graphics card and still no power

    Just got a brand new 725 watt psu with an 8 pin connector and the system is working great
