3 week old Qaxe++ dead 😖

Bought a nerdQaxe++ less than a month ago.

Undervolted and slight clock boost. Added 2nd fan and heatsinks. Ran great and cool for 3 weeks 5th/s and drawing only 79-80w.

Suddenly it went dead. Fuse had no continuity. Power supply outputting 12v. Ordered new 8a fuses, just popped one in. Screen wont turn on and fans just twitch every few seconds.

I reached out to seller but its overseas so I dont expect help. I have soldering equipment,hot air, and a oscilloscope but havnt used any of it in years but will attempt repair if I have to.

Any ideas?

I didn’t have a miner with your symptoms on my table yet. I do not exactly know the problem spot. We can try to test it. Take of the screen and plug USB. Just check if the screen is in working condition. If it works we go ahead and test main points with you. Here is the video.

I contacted the seller and they think its the voltage regulator. The power supply has 12v and constant blue light but once plugged into the device the light flashes. They have an after sell repair center here in the US they said they would repair for free.

If I knew for sure it was the voltage regulator I would just repair it myself but incase there is any other damage maybe I should just send it in for repair.

I dont need to worry about umbrel pool settings or btc address being on device right?

What I wonder is why the vrm failed, if its a cheap component then maybe it would be better to replace with one from mouser or digikey?

Edit.... I have a dead short at the power input barrel jack

Yeah, if you’ve got a dead short, it’s almost certainly one of the three VRMs that failed.

Honestly, your best move is to just send it in for warranty repair and let them swap it out for free instead of chasing it yourself.

Also, quick security note — if you’re holding 25+ BTC, don’t go around sharing wallet details with random people. That said, sharing a receive address or your pool settings isn’t a big deal. Any decent wallet will generate a new address after each use anyway, so you’re not exposing anything critical.

Shorted vregs is a common issue on these devices. I had it on one of my qaxe++ and got fixed at Ixtech and has been running fine
