Cold boot problems that go away after a reboot are very often pw supply problems. What happens is that the capacitors in the pw supply discharge over time. When you first pw ON, there just is not enough pw to boot the system. After a restart, it works.

I have never heard of the pw supply you list. The very first thing I would do would be to swap in a known good, quality pw supply. Something like a high end corsair or seasonic unit.

As a simple test, pull your video card out and connect to the onchip video. If it boots ok with the onchip video, you know you have a pw problem.

You didn't completely describe that graphics card, but it appears to be a dual-width, dual-fan model.

From what I can determine, it's power-hungry and requires a minimum of a 500 watt power supply.
