    EVGA RTX 2070 Super Black with u610 blown up

    I have an RTX 2070 Super from evga with a blown up IC. With the IC on the card, pin 17 had a short to ground. This pin is connected to the 5V rail by R993, a 0hm resistor. I removed both U610 and R993, to discover that the 5V rail has 800 Ohms of resistance to ground. After checking some resources online, i found a picture which describes the usual measurements a Turing series GPU should have in order to "work properlly". Interestingly enough, this gpu doesn't have U31, the IC responsible for the creation of the 5V on the card, as well as no L47.

    Are these 800 ohms rigth for the rail, or could there be another bad component?

    I'll upload the schematic for an Asus RTX 2070 super which i've using as a guide, as well as the repair wiki where i found the "normal" measurements guide for this generation of nvidia gpus.

    Thanks everyone and sorry for the bad english, feel free to ask for more information if i didn't made myself clear.

    Note: in the link i have provided with the measurements of a turing gpu, there are 2 gpus as an example. On the bottom one, the 1.8v has the exact same resistance as the one on my 5V rail. Maybe is this the correct measurement for this model?

    replace that 8pin little ic that make 5V near coil

      Are you talking about u32?

      Edit: I have lifted coil pack L44 L45 to check where the 800 ohms resistance comes from. With the coil lifted, the pin that connects to U32 has a high resistance in the millions of ohms, and the other side is where the low one comes from. U32 is fine.

        Update:
        its been a while since i worked on this gpu. I have replaced u610, and know 5V are present on the card. Vcore is missing, after reading and analyzing the schematic for a while, i discovered that u606 is the one responsible for creating Vcore. u606 has no voltage present on PIN 36 (EN pin)

          do u have 1.8V or PEX or memory voltage?

            1.8v is present. PEX and memory voltage are missing

              Hello this Gainey. The PDF for the EVGA 2070 Super will be a great help. thanks a lot.

                u can only compare to other boards. check if u have pgood on 1.8V ic and follow it
