GPU probably dead need help to verfy

[Apocalipse]

Hello everyone, for a short intro into the problem please check my recent post for my PSU (I'm on my phone so it's not easy to post the link, the PSU now is a CM V850)

I try ed to power on the PC and I saw smoke coming from the GPU I immediately flipped the PSU switch and disconnected the cable. I opened the GPU up, and it doesn't  seem to me like anything is fried, then again I'm not an electrician.

The GPU is a gtx 660ti asus top, and the second picture is the close up of the area where the smoke came from

VRM mosfet may have asploded. It can be repaired, but it aint easy.

[Levent]

there is no way to confirm at this stage as I dont see any visual damage you gotta try it out.

Is not easy, as in i could not do it or, is not easy as in a repair shop couldn't  do it?

NO!

 

If the smoke had been released, do NOT power anything up again. take the VRM heatink off of the card and inspect the components underneath for a blow hole or cracks

[samcool55]

Can't you remove the heatsink?

For a beginner in soldering, it is nearly impossible. for someone with experience, it is still somewhat difficult. The PCB acts as a great big heatsink and makes it difficult to melt the solder on the board. I have repaired motherboards and GPUs before

Like I said, I tried it, the PC won't boot with the gpu inserted and connected to the PSU, but it will boot if it is not connected to the PSU, at which point the fans of the GPU will start to spin for some reason.

The heats ink is removed?

Do you mean the heatspreeder of the VRM? 

[iamdarkyoshi]

yes. It is likely that one of the mosfets underneath asploded.

I cant verfy.

Maybe try using it again, if its gonna fry its gonna fry nothing you can really do about it.

Well you can avoid it getting worse, the gpu is probably dead, and if he tries to use it, and it burns further, the whole thing can short out and could damage the rest of the system. You don't want that to happen.

[Apocalipse]

yes. It is likely that one of the mosfets underneath asploded.

Dammit i can't seem to figure out how to post a picture of the other side of the gpu. There is a stain

On the back which seems like an oil spill.

Its small in diameter and I can't seem to get rid of it.

for the record this stain was here before this happened. 

I did not mention that the gpu is old around 2-3 years.

Looks like the VRM is fried if the smoke actually came from where you pictured it. There is no real way to fix this, besides sending it to ASUS and having them repair it at a cost (unless it's still under warranty). Can't say I've had this happen to me before, especially with ASUS cards. I feel sorry for you dude, I really do.

 

EDIT: Either RMA or get a 960, much better performance than you 660 Ti. I use a 760, btw.

yup its dead RMA it like nothing happened.

[Apocalipse]

yup its dead RMA it like nothing happened.

Damn u wish I could, I got it while  I was in Germany, and I don't think I could RMA it back there.

I had huge issues with their motherboard back with the maximus III, and not just me. As for the RMA, does anyone know how to RMA to a different country

i think asus voids warranty for removing the stock cooler, you may be out of luck

From an experienced guy with heat guns and soldering irons who has built electric guitars, circuit boards, and so on....you won't fix this easily.  You pretty much gave it smoke damage which can kill the circuitry of the VCard alone, and just from the pics alone it is hard to tell what went wrong.  Different parts would need to be tested for one to tell if there is proper flow through them, it probably also needs to be reballed and/or reflowed properly.  Your basic soldering iron won't repair this due to the lack of heat.  These components usually need a heat gun that at least hits 600 degrees F for the reflow, the right type of flux, and most likely a reballing kit cuz I am positive those connections aren't right anymore.

Well thanks to everyone for helping out il try to RMA it or maybe get a gtx 660ti which I don't want to do in anycase since I planned to get a new GPU with the series after the 900 series.

If you saw smoke you would be lucky if the VRM blew I'll be honest. If a trace blew you would be in deep shit. Traces are much harder to fix and personally at work I can replace anything besides 0402 and blown traces. That's what we have technicians for. (I'm a electrical engineer, focusing in circuit design)

Any idea how much could that cost?

I have no idea how to sodden, and I think it's to late now

I have attempted a repair on a GPU that had some VIAs corroded from water... it actually worked after I repaired it. I have also replaced a sot23 package on my motherboard that asploded from a faulty DVI cable.

To fix? Depends on the soldering iron. You'll need a nicer one and it could be pricey. Buy leaded solder as lead free solder is junk. To fix the traces it is as simple as cleaning up the blown trace and resoldering over it. I'm not sure how much it would cost but I'm sure if you looked around for quality soldering irons you could find out.

Vias shouldn't be a big deal as a good layout person will put a lot of vias over the entire board. (minimizes signal loops decreasing noise.) Props on the sot23 though. That would be too much work and effort for me Hahaha.

Basic soldering irons go for 20, but that depends on the amount of heat. Higher heats drive the price up. I was lucky to get a 600/1000 heat gun off ebay just got done a reflow, and now my ass hurts from the stone ground. But, ya 125 irons[not guns] go for like 20 bucks in most cases. It will add 5-20 up from that if they need more heat.

Sounds about right. Unfortunately I know nothing of how gfx cards are done or the VRMs as I do analog design. You might get away with a cheaper iron but if those are solder to a ground plane you're going to have a bad time.
