Melting SATA data cables

Just recently built a new gaming rig, specs are as follows:
AMD Ryzen 3 2200G using stock AMD cooler
MSI B450M Gaming Plus mobo
8GB of Team T-Force 3000mhz DDR4 RAM
Corsair CX450M semi-modular PSU
Inland 240GB SSD
WD Blue 1TB HDD

After I built it, it wouldn’t come on. I can’t remembered what I unplugged but when I did it came on and has been coming on fine since. Can boot into the BIOS fine. But I’m getting no reading of a storage device, when I hooked up the SATA data cable to the SSD it gets really hot and starts to smoke and melt the cable, but only on one end of the cable. So I decided to see if I could at least get the HDD to recognize in the BIOS. I originally had the HDD SATA power cable hooked up but not the data cable because I wanted it to boot off of the SSD. Hoooked up the data cable to the HDD and the same thing happens, one end starts to melt and the cable gets hot and starts to smoke. These are the stock cables that came with the MSI mobo, poorly constructed and cheap cables or a larger issue at hand? Everything else seems to be fine and is be recognized in the BIOS besides a boot device. Any help is greatly appreciated, order new data cables and will be here tomorrow. The HDD was used but was cleaned and in good condition. It happens regardless if it’s the SSD or HDD, melted both cables that were included with the mobo.

If you're sure the standoff situation isn't the issue, is it possible some small part like a screw rolled beneath the board?
Might also possibly be one of the SATA storage devices (or its header) is bad and back-feeding raw voltage to the SATA network.

You must have a problem with the board or the devices themselves. There is no power on the SATA data cables, only signals. The only way they could get hot and melt is if something is mis-wired.

One thing I can think of to check is if maybe you left an un-needed standoff screwed in and it is shorting across traces under the motherboard.

@clutchc I’m only using the correct amount of standoff’s that the board requires. Thinking it’s a PSU ground issue maybe. That’s what I don’t understand, it’s a data cable it gets now power. Only transfer data and signals. The board is brand new and everything reads correctly in the BIOS other than the storage. I’m going tomorrow to buy a new PSU and SSD. I have new cables coming in tomorrow as well. Going to give that a go. If the cables still burn then I know I have a motherboard issue.

Right, but that does not seem to be the case here.

Additionally, you can't split off data cables like that.
Power, yes. Data, no.
