I can buy bunch of them at 1/3 price of second hand ones but can preliminary test them/ select best if I not touch amd warranty seal on heatsink screw, I can remove back-plate
In first batch I see 2 with dead short on 12V molex and when injecting voltage I see no voltage leak to output caps here some resistance values on output caps Red is from working Sapphire RX 6700 10Gb due sharing this same PCB layout I suspicious of blue one is no repairable due low resistance
But I surprised by third one that do not have short on it because 2 middle 12v filtering caps on left side no longer make connection to molex and have dead short with GPU core when injecting 1V on them I see voltage leak via core to right side 12V caps.
Any advice how to preselect best candidates for repair or this is not worthy for this price ?
