Story:

I recently got a 4070ti. I swapped out my old 650w for the new, high quality 850W PSU.

I found my CPU was overheating, as I hadn't upgraded the cooler since my old Ry5 3600.

I purchased an AIO cooler and installed it.

I had replaced most of my old PSU's cables with the new ones... except the SATA cable, which connects the AIO Commander Core (hub) to the PSU, as well to the mobo USB.

I turned on my PC, it crackled, smoked... and the wire from the hub to the sata cable melted.

I turned it off very quickly and unplugged the PSU and SATA cable.

I put my old cooler back on, after a couple hours, cleared the CMOS, and tried to boot. Everything inside turned on, all fans/lights, but the PC did not boot, and my peripherals (mice, keyboard, stream deck, gamedac&headset) did NOT light up. The power button also did not turn it off, so I had to kill it from the PSU switch.

My assumption is I fried the mobo, or possibly the PSU.

My question is, how likely is it I also fried my new GPU/RAM?

I have a replacement PC coming tomorrow, sans GPU, but I am unable to test if my GPU works until then.

I know this is hard to answer... just looking to calm my anxiety.
 
Its a tough guess, but it *might* be fine.
The PSU should have the necessary protections that if a failure happened on the SATA rail, it shouldnt cause any damage to the 12v rail (PCIe).
It is highly likely it just fried the motherboard, RAM is a concern but I think a single component failure is more likely.

That said, as a caution NEVER reuse PSU cables between different models unless you are absolutely certain they share a kit (Corsair sells kits that span PSUs, for example).

Thank you, I appreciate this.

I actually found solace in the unfortunate hilarity that I had researched quite a bit, as I tend to, but never came across mention of this regarding the PSU... and upon first research after the event this was what I found.

I was kicking myself all night lol.

Yeah I saw a video of a guy that fried over $3000 in components because he used the same cables after a PSU swap.

Yeah, thats not good.
Some parts are dead.
 
I hope everything other than the PSU and 5V rail components are okay, but this is precisely why every PSU manual says some variation of "only use cables for this model". With luck this won't be too expensive a reminder as to why you should always at least take a look at the documentation that comes with any piece of equipment.

I'm assuming my CPU is probably toast.

Really all I care about is the 4070ti. I just got an entirely new rig from my friend today, as I am DONE messing around lol. I'm going to plug in the 4070ti tonight and try to boot. If that works, I'm happy. I'm hoping I can still use my old RAM and SSD, but the RAM and SSD that's in there isn't much worse than what I was using.

Wish me luck.
 
Good news everyone,

I got a PC from my buddy and managed to salvage my GPU, RAM and SSD. All work fine, with a new AIO.

The 4070ti is still currently daisy chained, but I've been monitoring it closely and it seems to be fine with a new 850w EVGA superNOVA.

Problem solved!
