    Gigabyte GTX 1080Ti Turbo Missing Capacitor

    I'll check out the secondaries a bit later when I get some more time. I did a bit of tracing and it looks like the damaged circuit is hooked right up to the sense pin of the 6 pin power connector. Going to explore that a bit further. Tested the diodes and they are functioning correctly, also...

    Gigabyte GTX 1080Ti Turbo Missing Capacitor

    Resistances (In reference to ground) 8 Pin + 6 Pin ? ? ? 0.8 M Ohm N/A ? ? ? 0.3 Ohm 0.8 M Ohm 0.3 Ohm 0.3 Ohm N/A 0.3 Ohm 0.8 M Ohm 0.3 Ohm The gnd and sense pins all seem good, but I am unable to get a stable reading on the 12v pins. I can measure 0v on the pins to ground, but once I...

    Also found a resistor that was a little messed up right next to the HDMI output. Soldered it back in place, didn't fix card though.

    Gigabyte GTX 1080Ti Turbo Missing Capacitor

    Yeah, the 0402 has some damage. I probed the pads and they are run in parallel. Don't have any 10uF SMD caps on hand, only relatively large through hole, will have to order some. Haven't been able to find a schematic anywhere, and only have found more detailed board info about different...

    Gigabyte GTX 1080Ti Turbo Missing Capacitor

    Good call on cleaning the pads. Can't find my calipers but comparing it to the SOT23 next to it, I am thinking either 0603 or 0805 Not a reference board. It's the gigabyte 1080ti "turbo", which is apparently the same layout as their "gaming oc" but not the "aorus extreme" Edit: Thanks for...

    Gigabyte GTX 1080Ti Turbo Missing Capacitor

    Hello all, I picked up a non-functioning 1080Ti, no longer under warranty. The card has no display, the leds next to the power connectors flash briefly when first booted then go dark immediately. I noticed that there is a tiny cap that is loose (only connected to one pad) with the larger one...
