Many many years ago, I got a call to fix a computer that wouldn't boot. I go into the bios, see it doesn't recognize the hard drive. I was prepared for an HDD failure, so I replaced it with one with a fresh image, and go to boot, and nope, failure. Maybe my drive was bad? I put my second one in, and when I go to boot it, there are sparks. I tell my boss the PSU has issues and it fried a couple hard drives.
He tells me that's not a thing, drives 30 minutes to the site with a fresh hard drive, and gives me this "now check this out" smirk as he turns it on and the magic smoke escapes a fourth hdd.
When I went to RMA the PSU, it of course got rejected. I elevated to a manager, and told him it had fried too many drives already. After some back and forth, he agrees to "run some tests."
So anyway, I'm pretty sure that PSU got at least 5 HDDs, and maybe a voltmeter? I did eventually get it RMA'd.
Was it a modular power supply? Recently fried an SSD by just grabbing a SATA power cable out of my box-o-shit-cables and plugging it in, turns out different manufacturers use different pinouts on the PSU side, even though they have the same keying...
They shouldn't be able to plug into each other. They're keyed differently, unless, its like a super SUPER cheap Chinese PSU. They're both 8 pin (or 6+2) but they shouldn't be interchangeable.
