I think I may have found it? Not sure though. I have this .93 k ohms on a CAP PL 560UF/6.3V 6.3*9DIP20%T and it says
The reading of
0.93 k ohms (930 ohms) on a 560µF, 6.3V capacitor indicates that the capacitor is likely faulty , specifically that it has a high internal resistance or is possibly leaky . A healthy capacitor, when measured with a multi-meter in resistance (ohms) mode, should show the resistance increasing until it reaches infinity (open circuit) as it charges. Do I believe the google AI? I have replacement caps but if I am wrong then I am just barking at shadows and...

ASUS z490-p "load-dependent" fault
hello, I am working on a short that isn't on the main power source (battery/PSU) but is downstream , located in the components or connections between the 3V rail and the dummy load. Do I check caps and mosfets first or can I inject voltage again on downstream rail as I have removed the resistors isolating the dummy load? This is so cool btw.{not going to tell the ladies though as I think it will add a dummy load to my game}. My thoughts, as there are 2 resistors that do have circuits in common they differ in others, and that may narrow it down. OO and thanks for the boardview. I had the file... -

I did find a short on the 3.3v rail 2 100ohm resistors, I removed them and replaced with new and the short is there again. I want to know what those resistors went to. Does anyone have the asus prime z490-p boardview file to help?Leave a comment:

I am newb at this or dangerously educated. Kinda like mickey mouse in fantasia where he uses magic to clean up the place and boom all messed up....Leave a comment:

I have one as well, it is short to ground on the 3.3v rail. I hope it's not what i fear it is lol. I am going to inject voltage to it when I complete the other checks and test a few other components to make sure I don't inject into something that will fry it. I think 1v .05amp to start is safe? I am getting my thermal cam soon and want to try it out. I would use IPA 90% but that's why I bought the camera. Anyone have suggestions or warnings?Leave a comment:

I will check the other packages that look identical. I also have a b450 steel legend I am stabbing around with and Have a suspect short , being new at this I will second guess myself. Measure twice cut once has always been a rule of mine. I have a 8 leg mosfet not reading ground on any of the legs.All the others read a ground on 1 leg., there are 3 of them the same component. Should that mosfet be reading a ground or is it shorted? I am checking the surrounding caps and they have ground. That to me indicates a short. Is there a cap or some other part that would disrupt the ground rail on the ...Leave a comment:

Greetings all. Blew a cap off and don't know the value of it
I found a short on a mosfet in the vrm and used my air station to remove the bad component. and after viewed my work and noticed that had also blew the cap above it off as well... it went to cap heaven. I don't need the boardview file just what cap values are needed to replace the component. This is on a gigabyte r927xoc-4gd Windforce. I am a novice at repairing as that was a rookie mistake, + side is removal of the shirted package cleared up the short.1 Photo
