**and NO - There is NOT anything on GPU PCB to prevent short or power surge. GPU are "dumb" component.. not "active". When you short the GPU.. you blow components.. there is no "fuse" of any kind.. not even on top-tier GPU's.

Check this out (also just Google graphics card fuse)

Besides that I can take some pictures of a least three cards, I'll look around and see if I can confirm fuses being on newer cards though.

Oh look I found a fuse on a GTX 780
also a 7970
(hint: component code "F")

Will you retract your statements or should I keep linking pics?

 You should keep digging.. and reading. While your at it, trace that connection and see just what that "F" is for

How do you propose that I trace the connection on a multi-layer PCB?
post #46 of 48

same way you trace a wire from one end to the other...

 

A. visually - good luck

B. using continuity and DMM

With the 7970 the only component with printed code of F, that I see, is F1800 top right. Which is no where near the power delivery. Which makes no sense for a fuse.

For one F1 on the 780
Second, suggestions as to what they could be if they are not fuses. (I'm basing statements on what I know, and referring to links/pictures, whilst you are referring to.. If you can actually find out what they are, I'm eager to learn)
Third, to for example guard against a short on the connectors, it can be placed anywhere along the connection in series, or even in parallel assuming enough math is done beforehand
Fourth, if logic/sense is a valid argument I will state that there's no reason not to have fuses in a graphics card.

So.. you're going to send me one eh-smiley.gif
