Re: Sapphire HD 7870 possible short
Also I have to mention that if I plug just one power connector the fan is spinning. If I plug the second power connector the shortcut is present. In conclusion the shortcut is on the second rail (the exterior power connector). Maybe someone can explain what is powering this circuit and haw to identify the defect. Thanx

Re: Sapphire HD 7870 possible short
Hy guys. I have the same card 7870 2G, and a shortcut on the chard.
1. Starting the pc the power source is beeping (shortcut detected) and shuts down.
2. measurements: GND - MAGIC R19 = 0,3 ohm
12V- GND = 600 ohm
1R0 - GND = 210 ohm
Can anyone give me a starting hint to detect the problem.
Thank you.Leave a comment:
