Stuck in Bios, Sata ports not detecting SSD or Hard drive

I recently bought a new power supply, a Corsair RM650X, hooked it up to my pc, pressed the power button and all I got was a quick flash of the lights, then nothing at all. DOA, sent it back defective. Hooked up the old power supply and it fired right up, no issues. Bought a new power supply, Seasonic focus plus 750w, Same issue. DOA. I let the computer sit a few days before putting back together and sending the Seasonic back defective. I put the computer back together and fired it up with the old power supply. This time, it went straight into bios. I checked to see if it was recognizing any of the Sata ports for my SSD and hard drive and nothing. Checked all my connection, tried swapping the cables into different ports, new cables, and nothing. Still the same issue. Then my old power supply died. Great. So I borrowed a power supply that I knew was working from my buddy, and it turns on again but still goes straight into bios. Nothing in the Sata ports is recognized. What is going on?? Did the last power supply that was DOA ruin something in my system? Maybe my SSD and my hard drive?

Gigabyte GA-AX370-Gaming K5

Corsair Vengeance LPX 16G (2 x 8GB)

Ryzen 7 1700x

EVGA GTX 1050 TI

EVGA 280mm CLC

Sandisk 240GB SSD

1TB hard drive

Thanks!

Even If it still goes in to bios? I believe the motherboard is still under warranty. I bought it in November

Okay, so I have tested all those different scenarios and still the same results. the only thing with removing the GPU and using on board video is that Ryzen does not support that. The motherboard still seemed to go to bios through the diagnostic lights. Ill send in a request to Gigabyte and see what they say.
 
So what it's prone to failure by being an amd? Really??

I work in IT and rarely have seen a bad CPU. The fact it boots and goes to bios but no ports found says motherboard to me. I once cheaped out on a PSU when I was younger (back when we were using IDE drives if anyone else remembers those). But anyway, put a cheap power supply in, few days later, couldn't boot up, board didn't see any of the IDE ports or anything. Ended up that tigerdirect let me return it and I got a new one.

yes, when working with a major reseller i saw more amd CPU failures in a month than a lifetime of intel. even though sales were dramatically less, we received more or comparable RMAs vs intel or nivida based equipment.
e.g. amd chipset mobos, regardless of brand & plenty of sapphire graphics cards (theyuse amd chip.

Things may have improved with ryzen, and i agree CPU failure is rare, but from what i saw it cant be ignored as a possibility.

Also that was the final nail in the coffin for me selling/using gigabyte motherboards, which i have done since the 90s. While i dont recommend Asus monitors, asus mobos are the choice. One funny thing was we saw more returns for ROG asus mobos than their 'normal' mobos

It ended up being that both drives were fried.

really? both drives but not the motherboard or ram?!
wow, im suprised.

usually bad psu blows mobo first (if it does ruin anything). Sucks that both the drives went. also unlucky was that corsair rm series isnt a bad choice.
sorry to hear

Yeah, I have it up and running now. Should have know that seasonic pins there outputs differently... That was an expensive mistake. Regardless, I had still received a bad power supply before hand. I have another seasonic and it works beautifully.

They do, and I'm just glad that it's up and running and nothing else was ruined.
Thank you for the help!
