Computer shuts down with HDD or SDD plugged in

[chipwitch]

Hello, a couple days ago, I smelled something coming from my desktop computer case. Before I could positively identify the problem, the computer shut down. I immediately removed the PSU and determined that the smell (burning electronics, like hot clutch or brakes in a car) was definitely coming from the PSU. I did the paperclip test on the bench. Everything seems fine, but I can't load test. The entire system is only a year old. Still under warranty so I'm sending back the PSU. It's a Corsair cx750-m. In the mean time, I ordered another PSU. A 750W EVGA. After plugging it in, I could only get the computer to boot to the UEFI as anytime there is anything plugged into the power jacks, besides the MoBo, the MoBo will shut down in milliseconds. From the UEFI, all the temps look normal. The CPU is hottest running at 45C.

ASRock x99 extreme4
GeForce GTX 750 Ti
i7-5820k
16GB DDR4
500GB Corsair SDD <Edit = The PSU is a Corsair. The SSD is a Crucial>
2TB HD
Windows 7-64.

As you can see, the 750W PSU's are overkill. Any suggestions? I still have both PSUs but since I KNOW something was burning in the old one, I'm afraid, though tempted, to reinstall it.

Do you have any old components or access to another computer to test out your components? If so, you could test your hard drives on them and rule them out as the issue.

Sometimes depending on why and how the PSU went, it could have damaged your motherboard, drives, CPU, etc (although most likely the motherboard took the brunt of the power issue). Maybe try plugging in your drives to different SATA connectors.

It sucks and is time consuming, but if replacing the PSU didn't work, something else got hosed (assuming you properly hooked up all the power connections correctly after replacing the PSU).

what Os was installed R prior?

LOL

Sorry, I don't see the humor or the point. The emphasis is on SEEMS, if that's what you're getting at. Voltages all check out. Get it? SEEMS ok, but without a load test there's no way to know for sure.

I don't know why people feel the need to post smart ass comments rather than attempt to help.

Hi, I didn't think I had anything to plug in as this is a new system. All SATA. Everything else I have predates SATA. Or, so I thought. I found a 2TB HD I'd forgot I had and tried it. It works fine.

So, further investigation revealed every drive that was plugged into the PSU got fried! I lost a 1 TB HD, a 500 GB SSD and a DVD drive. Tried each individually. No Joy. Most likely each was shorted out by the PSU. The MoBo has protection circuits that monitor the PSU signal coming in. ASRock, you rock! Saved my i7-5820k!
