[SOLVED] Asus ROG Strix Z490-E burned up

[Croman38]

I'll start off with the parts I was using:



- Asus ROG Strix Z490-E wifi

- Intel i5 10600kf

- Corsair Dominator Platinum White 2x8 gb 3600 mhz

- EVGA GTX 1080ti ftw3

- Deepcool Castle 240 rgb v2 AIO

- Gamdias Kratos P1-650w gold

- LinkUp PSU cable extensions

- WD Black SN750 nvme

- NZXT H510i w/ built in fan hub

- NZXT Aer2 rgb fans x2 (120 rear, 140 top)



So I was upgrading my mobo/cpu/ram (previously 4690k, asus prime Z87) along with the new additions of the psu cable extensions, nvme ssd, and the 140 nzxt rgb fan. I had just finished installing everything, and the first thing I noticed was that as soon as I plugged in the power cord into the power supply, the ROG led's on the board lit up even before I pressed the power button.

When I did press the power button, the nzxt fans lit up for just a split second before immediately turning off again. The ram led's however, lit up and stayed on. The aio cooler never lit up at all.

Like an idiot though, I tried pressing the power button again maybe around 3 more times, with a few seconds in between each try.

Each time, the same thing would happen with the fans and ram, until finally I saw and smelled smoke coming from somewhere on the board. I immediately turned it off, but I knew it was already probably too late.

Everything looked ok from the front, but as soon as I took off the side panel I saw the short right away. I proceeded to remove everything from the board, double and triple checking everything as I go.

I checked all the headers, fans, and power connections and there were no mistakes. I also checked the cable extensions as I feared that I somehow connected something wrong, but they were all correct.

There were no loose screws or anything like that, and all of the standoffs were properly seated and screwed on.


What could have caused this?

Could it be that I was simply unlucky and got a faulty board? I'm planning to pick up another board (fingers intensely crossed that all my other components are still ok), but I am worried that the same thing might happen again.

I was so excited for this build and spent nearly all weekend installing everything as perfectly as I could, and my heart just absolutely sank when I saw that puff of smoke. I've built around 7 or 8 pc's before including for family and friends, and I've never encountered anything like this. Any help or insight would be greatly appreciated! Thanks in advance!

The ROG logo in RGB is always lit no matter if the computer is started up or not, as long as the PSU is supplying it power. That is perfectly normal.

The place of the issue doesn't look like any wrong fan/power connections can cause, and I looked up the power supply, seems to me it's a decent unit and is also unlikely to cause the issue.

Also it seems like the place underneath one of the VRM burnt, you might see more damage underneath the VRM heatsink. I'm leaning towards a faulty board for now, try to contact Asus and tell them what happened.

Ah, I see. Yea I'm trying to get in contact with Asus Canada now.

What do you think are the chances my cpu, gpu, ram, and nvme ssd are still ok?

All of those are brand new except for the gpu and I'm really hoping they're unharmed..

Thanks for your input!

I'm unsure if the CPU is unharmed, since it seems to me with an issue with (or affecting) the VRM, which supplies power to the CPU.

All the other components doesn't have anything to do with VRMs so I think they're okay. Do you have a spare computer to test everything else out?

VRM is dead RIP motherboard. Hopefully the CPU and memory is okay. Your only choices are are to get another board or RMA this one and wait. Then wait and wait again.
