Is my motherboard or drive bad?

[1Poseidon3]

So I just got a new hard drive on Black Friday sale. I plugged it in just now and booted up my PC and it will not show up in the Disk Manager even after a disk rescan. I had this exact same problem with an SSD that I bought a few months back but I figured that was just DOA. Now that this drive is not working as well, I'm starting to get suspicious of my motherboard. I bought an M.2 SSD a while back and plugged it in. When I did that, it killed my HDD that my OS was on and my other SATA SSD. Luckily, my other extra storage drive wasn't killed. I'm thinking that the M.2 drive might have fried some of my SATA ports. Is that even a possibility? I rearranged my SATA cables for my hard drives into different ports and the drive still isn't working.
Here's what I'm thinking:

The drive is DOA

The SATA ports are fried

My power supply can't supply enough power to run the drives

Any other suggestions are welcome. The drive in question is a Toshiba X300 4 TB. The other drive that I have in there that still works is also a Toshiba but it's only 1 TB. The motherboard is a GIGABYTE Z170X-UD3. I honestly don't know what wattage my PSU is since I can't find the box or order info online and there's no wattage listed on the unit itself. Thanks!

If it is true, you are better to buy other good PSU ASAP.
Like this one, even it is the old model https://www.newegg.com/Product/Product.aspx?Item=N82E16817151094&ignorebbr=1

I just went all in and purchased a new EVGA 850W Plat PSU so I should be good on that front. In the mean time, I've messed with the cables and their configuration on my motherboard and I've come down to the fact that it is either the SATA cables or the SATA ports but I cannot figure out which. I've had both hard drives being read (not at the same time) but now I'm down to the point where neither of them are being read even on ports they were previously being read on. I have absolutely no idea what this means or why this is happening. I'm at the end of my rope here. 🙁

EDIT: Okay I finally found the combination that gets both of my drive working which is good. However, this makes me think that the ports on the motherboard are bad which is very bad. Does anyone have any suggestions other than buying a new motherboard? Because I really don't want to spend the time or money on rebuilding my PC with a new motherboard.

Because you used the M2, you should check the MB manual, because some of SATA ports will share bandwidth with the M2, if you used the M2, those SATA ports will be disable.

If I can find it I'll check but this is probably the case. For the time being I just bought a PCI-E SATA card with 4 ports and some new SATA cables and everything is working great. On the up side, none of my drives are actually dead 😀 Thanks for the suggestion though.
