I've built a new PC using all new components apart from the HDD and the RAM. As far as I know everything is connected properly, yet it will not post and ends up in a continuous boot loop.
I get continuous short beeps from the speaker when it starts up, which research has told me indicates a power error. Both the 24-Pin connector and the 12V connector are plugged in and are secure. I have also tried 3 separate Power supplies and I have the same issue with all of them.

I have removed each component one by one to try and identify another possible issue, but I have the same issue every time.
Currently I have the motherboard out of the case on its anti static bag on a hard surface, with only the CPU, cooler, RAM, PSU installed. I am still having the same issue.

I am at a loose end here and any help is appreciated.

Specs:

Motherboard: GigaByte GA Z97M-D3H
CPU: Intel i5 4690k 3.5GHz
GPU: MSI GeForce GTX 760 (not currently installed)
RAM: 2x Crucial 4GB DDR3 1333Mhz (from old PC)
Cooler: Cooler Master Hyper 212 Evo
PSU(s): Corsair CS650M (brand new), Corsair CX500M (brand new), Corsair CX600 (from old PC)

Yeah, that's the PSU failure beep code for Award BIOS. Assuming you pushed the 24 pin and 8 pin plugs down until the latch clicked and you're absolutely sure at least one of the PSU's you tried is in working order, then you have a faulty motherboard.
Power issues typically prevent the system from attempting to turn on in the first place. Beep codes generally mean there is an issue with the RAM, or something is not connected properly. I would plug in a single stick of ram, make sure it is seated correctly, and unplug anything that is not necessary (GPU, drives, etc.) and see what happens next.
