gtx670 EVGA GTX 670 Mosfet

[Lukiao]

Hey folks,

currently building a budget second hand pc for my gf. One mosfet from the EVGA GTX 670 I bought on Ebay exploded when I started the PC, just saw a lot of smoke, but no flame. Can the card work without one mosfet? Or is the risk to high to fry the rest of the system?

Other components are mostly from my old build:

CPU: i5-6500

Mobo: AsRock B150m Pro 4s

RAM: 2x4GB G.SKill DDR4-2133

PSU: Bequiet Pure Power 400w

That is an SMD resistor (or capacitor?), and it is possible to solder one on if you have the skills. As for using it without that one part, I'm not sure how well it will work.

Ups, I attached the picture from the wrong side. Here you can see the exploded mosfets.

It is most likely possible to replace it, but i wouldnt recommend starting that card without it.

This looks like one of the chips popped, are you sure it's the mosfets and not something else?

Q20 Means that it is transistor/mosfet 20

if the damage is visible from both sides then i'd say that card is done for.

Well, I guess OP can look up the numbers on the other mosfets and get one just like that, but then they would need to do SMD soldering in a really cramped space.

Not worth to repair at least, especially if he cant do it himself.

Okay, but thats not worth it on a 25€ graphics card for me.

That card performs on par with a GTX 960, and not far below a 1050 Ti. Assuming the requisite skills and part are possessed, repairing it would absolutely be worthwhile.

sure you can run without a phase, given that the voltage controller is stupid enough or its run of a doubbler. you can replace it with an identical one, make sure you replace the cap that was also blown too or remove all of the left over bits to make sure nothing is shorted and try booting

Not if he has to pay someone. Plus it doesnt look like only the mosfet is damaged, other layers are most likely damaged aswell, since its visible on bottom layer. Also the pads are ripped off it looks like.

If you can't repair it yourself it's not worth paying someone else to do it. IIRC That's Kepler right? I heard nVIDIA was starting to drop Fermi from driver support (the architecture before Kepler IIRC). Might be better off just getting a new low-mid tier GPU, would probably run cooler and use less power over the long run.
