    Asus GTX 670 dcII burnt mosfet

    hi one of mine gtx 670 smoked a little and after dissassembling the card i saw some mosfet burned. (see picture)

    with a air station i can take out the bad one and replace it without the change of knock off the pad, or do i need to do something to avoid that?

    i cant find identical component, so can i order any "b20 p03" mosfet?

    i would appretiate any help you guys can give me.

    thanks

                      Asus X712EA 3 volts after the first mosfet
                      by AppleLover123
                      Hey guys,

                      i have a asus motherboard here and as the title says after the first mosfet (in the picture) there is nothing more than 3.15v.
                      I injected 19v and max. 1 amp at the charging port and there is not voltage drop or smth. It's just taking 19v and 1 milliamp.
                      Then i tried to inject 19v and max 1amp after the current sensor and there it first takes 19v and 4 milliamps and after 2 seconds it is taking nothing (no current).
                      I measured on the coils on board everything seems fine. Also the main power rail is not shorted (infinite resistance).
                      Now i thought something...

                      So I have this Asus GT531GT whose pad is burnt and it shows short to ground 0.8 even after removing all the connected mosfets and capacitors.

                      Image attached . The mosfet where the pad is burnt is PQH8102...

                      Asus GA502D keeps blowing mosfet
                      by Scotchmist
                      I have an Asus GA502D, it had a blown mosfet which I replaced and the laptop booted into windows, a few mins later it shut off, the same mosfet was blown. I thought maybe just a bad mosfet but same thing happened again, a few mins in windows and shuts off.

                      I have removed the mosfet and can run the laptop no problem

                      The MOSFET is FDPC5018SG

                      Can anyone point me in the direction of what could be the cause of this, could it be the controller rt3663bc?

                      Thanks

                      ASUS ROG Zephyrus GPU Mosfet repeat failure
                      by MicroSMD Lab
                      The board number is GU502DU. I repaired this a couple weeks ago and it came back with the same issue, same mosfet failed (PQH9201). I'm hoping that the GPU was spared this time.
                      I used the same replacement part (purchased from Mouser) and I'm certain the soldering was done properly since it took just as much effort to remove as before. What could cause this same mosfet to fail? I'm thinking if it was unsuitable then the others would fail too. I looked for similar failures on YTube and the mosfet was replaced with AOE6930 in one instance and AOE6932 in the other but it's possible that the...
