Problem description

Repairing of a likely short on 12V which blew the corresponding fuse on a Jetstream GTX 970.

Example image (Figure 1) -- No image yet. Help expand this page by uploading it!

Symptoms

  • Not turning on
  • No fan spin
  • Not detected
  • All voltages missing

Solution

Most likely a problem with a VRM, check if any of the 3 fuses (AF2-10.0V125TM, colored brown, about 6x2.5x2mm and have a capital letter printed on them) are broken. The fuse is most likely broken due to a failure of a mosfet chip, however less likely but still possible, failures of any of the surrounding capacitors/ resistors. A deteriorated thermal pad, causing the aluminum heatsink to short the SMD capacitors is also a possible cause.
