4 Dead Seagate HDDs, 3 DOA: Bad luck or bad PSU?

A couple of months ago I switched out my PSU for a fully modular. After I switched my PSU was when the first drive died. It was working perfectly fine prior to that. I thought I messed up my drive somehow while switching PSUs.

I've only decided to RMA my HDD this month and so far I've been through 3 HDDs which do not work. I have checked in device manager, disk manager and BIOS and I could not find it anywhere. I've tried using the wires my SSD uses and I made sure I was grounded while handling my components.

Original HDD (1.5 TB Barracuda) : Dies after switching PSU. Tested on all ports with with different cables and on different computers.

1st Replacement (1.5 TB Refurbished Barracuda) : Dead on arrival. Tested on all ports with working SSD's cables.

2nd Replacement (1.5 TB Refurbished Barracuda) : Dead on arrival. Tested on all ports with working SSD's cables. Warranty transferred me to technical support to make sure my HDD was dead before transferring back to warranty after agreeing that it's dead.

3rd Replacement (2 TB Barracuda) : Dead on arrival. They sent me an upgrade after RMAing twice and this one was new. Tested on all ports with different cables as well as a different computer.

It's been 3 weeks and I don't know what to do. I'm beginning to suspect something happens the first time I power on my computer after plugging in my HDD.

I'm not exactly in a rush but at the same time it would be very helpful if I could. I've already considered getting a new drive but that's a lot of money.

Do I RMA this drive again? What would I say?

Specs:
i5 3570k
Z77A-GD65
Radeon HD 7950
Samsung 840 Evo
New: AX760
Old: TX650M

Kingston HyperX 2x4GB
CM Hyper 212 Evo

I strongly suggest that you stop blindly replacing your drives. If the drives no longer spin up, then the problem is most likely a dead PCB. The most likely reason for a dead PCB is an overvoltage from the power supply.

SSDs run from the 5V supply only whereas HDDs require both 5V and 12V. Therefore I suspect that an overvoltage on the 12V rail may be killing your drives. WD's drives would normally be killed stone dead by such an overvoltage, but Seagate's drives are better potected.

I would remove the PCB from each dead drive (with a Torx 6 screwdriver) and examine the following components:

But to be more helpful rather than just making a dig at Seagate, I doubt it's the power supply. I would RMA it again, then this time plug into a different machine first and test it. Then plug into your machine, that the only way to be 100% sure. The only drives I've had fail on me are Seagate, could just be bad luck but personally I've sworn off them now.

I've learned my lesson with Seagate drives. I'm about to buy a new WD drive maybe sometime this or next weekend for important documents and such. The HDD I'm trying to RMA was only going to be for my steam games and for my videos/movies.

I have another drive that I can test on different computers whenever I get home. It might already be dead already though, haha. Just hoping a computer will be able to pick it up.

Thanks guys! I'll post an update later.

Just saw your reply and I believe you're right. I did not mention that my computer would refuse to start up when I wired the 2TB HDD earlier.

If only I had listened to myself and exchanged my PSU the day I got it.

I'll check the HDDs I do have when I get home. If you're correct I'll see to RMAing my PSU. Say I do RMA my PSU, how do I know it will not screw up any new components?
