I'm having a hard time trying to figure out what is this component that burned in my VGA. I think that It was caused by a short and i Will replace the mosfet plus driver, but this little Guy right here is unknown to me, so maybe you guys could help me with this problem, It would be much appreciated. Took Photos before and after i remove the component

Circle the one you need (it is another card with a similar board, I do not know your board ID) and try to take a better shot so that markings are identifiable...

If it is the filter caps you are after, try the values I noted.

Im talking about these two IC's right here

On my card, the one that burned was the right one. Is it a PWM maybe? There are no numbers or letters on the IC to help identify it

The mosfets on this Gpu are 4C10N qnd 4C06N. Any change that those two are the same?

The ones you quoted are GPU VRM power phase components. The ones you show in the picture are probably used in the detection or steering circuitry to bridge the power between the motherboard 75W lines and PCIe aux power. They are still MOSFETs and so are Q42&Q43 (probably N-Ch) that control their state. Those usually end up leaking current to the motherboard due to potential difference and sometimes get shot if one of the shoulders in the VRM gets shot. I bet if you remove them and will try to start the card it will either not start or start with missing aux power indication.
Do not take my word for it, just check.

Here is a sample of this circuitry from another card...

Im starting tô think that the only way to put hands on these two ia finding another gtx 970 like mine, because theres no info on then... Is there any chance that evga would help me finding these two?

Let me ask on another forum, someone might have a junk board with those guys still on. I doubt EVGA will release any info to you unless you are an authorized repair facility.
Were you able to diagnose it? Just replacing components can run your bill up well beyond the card cost.

Edit:
As I suspected, both are P-Channel MOSFETs, use any 30V/70A you can get in this package. Check dimensions.
