SSD upgrade won't turn on

Hi to everyone. I did this upgrade with the ssd blade but the iMac won't turn on. The first green light turn on, but when I press Power button, this light goes off and on again and never start the computer. I had installed two differents ssds and neither works. I think the problem isn't the ssd. Any idea? Thanks!

Your diagnostic LED is saying it's the power supply. But before spending any money I would put it back into the original configuration and see if it works. What blades (specifically) are you trying to use?

Thanks for the answer! But in original configuration everything works fine. The PSU is ok :(

I'm using OWC Aura 6G
