Smoke from cpu/vrm area

[MattCaruana]

Yesterday I was building a friends pc, everything was going well until i tried to power it up. As i started the lights from the motherboard lit up and smoke went up from the cpu/vrm area, and later I go to find out that also his dvd drive was smoking. 

 

How can I know what is faulty in this build, i double checked that every connection was well inserted and in the right place. After removing the dvd drive the pc started and all the fans were spinning and lights on, but it didnt boot. Can you help me what is wrong pls.

 

CPU: I7 7700K

MOBO: Asus maximux xi hero

PSU: Corsair AX860

Cooler: NZXT Kraken X62

 

Thanks for all you help

Motherboard sounds fried, CPU is potentially fried as well.

Most probable you've fried the motherboard. Because if the PC turns on the fans, then power it is going through it. But some certain power to 'light' up a circuit that orders the PC to boot may be fried.

All in all, try to RMA the mobo.

Smoke is usually fatal so some things will already be damaged. You need to figure out why it happened. Is there a mistake or short somewhere? Did another component malfunction? It wont be easy...

 

I find it curious the DVD is smoking. I have to wonder if a wrong power cable was used somewhere.

Is there a way to know how did I fry them as all the connections where good, bad  psu maybe aswell, or bad voltage from the wall ?

Sounds like a problem with the PSU

 

Also if its modular check if you plugged the cables in the correct place

I would check that the PSU is working properly, something properly shorted on your MOBO so that is properly dead as well along with your CPU.

I think i will try to replace the mobo and psu, as i think that the psu shorted it out. The cables on the modular psu where connected properly according to the labels on the psu. The cpu is working fine as i tried it on my pc.

are you sure you put the cables going to the psu in the correct orientation?

Yes pretty sure as they wouldnt fit otherwise

If all connections were correct and in there correct places and all stand offs were in there correct places to not short the bored I would RMA it, there is a high chance it has fried the CPU if it was the was part of the power delivery that has burnt out, have a look over the bored both sides for signs of yellowing/browning to indicate there was a burn on the bored, the AX860 is rated 80+ gold so it's more liked the bored is the issue that the PSU, if it's the bored then the they should replace the CPU as it's there borers fault it killed the CPU, just be careful what u say to them, don't tell them it's ur first build and make sure u say u followed there guide, bored frying happens just not that often these days

Also it may just be that the DVD drive is faulty, not the first time just would be bad luck them both going at the same time lol
