    Component without datasheet IC's labeled "IN1S313I" and"IN1S424I"

    Hello
    I am troubleshooting a couple of coolmaster ATX power supplies.
    I suspected that the faulty components are the sps supervisor IC's labeled "IN1S313I" and"IN1S424I".
    I couldn't find any information about them online exept for their name, role and the manufacturer witch is "infsitronix".
    No datasheet, no pinout, i even tried to email infsitronix but no reply so far.
    I can't find a supplier to buy it either.
    Any help of how to test it and where to buy/order it is appreciated.

    Regards.

          IN1S313I-sag = WT7510A = EST7610A and presumably = PS113A

              Thank lotas,this is very helpful since the Weltrend ic's can be purchased while Infsitronix company don't have distributors (that i know of) and didn't reply to my email.
              What about the IN1S424I?
              I hope these pictures help

                  I can’t say anything about IN1S424I, probably some kind of relabeling of another chip.

                      Audio Driver/ Controller IC labeled GAD SHM? Datasheet
                      by Iceking007
                      Hello,

                      Could anyone provide me with some information on an IC labeled GAD SHM?

                      This is some sort of audio driver, it connects directly to left and right speakers via some inline resistors (small value of course).

                      I've attached an image of the chip on board, I counted 20 pins. It might be some sort of op amp; it isn't the primary audio processor, as there is a separate dedicated chip for that.

                      Thank you for your time....

                      Help finding datasheet for component marked G34662
                      by SoulFreeze
                      Hi, pulled this component, (I'm assuming it's a MosFET) from an LED COB video light. Im trying to find the datasheet so I can find an equivalent replacement but no luck. Any assistance with the datasheet would be appreciated.

                      Failing that, a way to pick a suitable replacement component? If it's indeed a switching fet, I'm assuming I might need to measure the switching clock frequency and find a component that meets the power capacity?

                      Its a pair of them driving a 130w Light. Takes in 19volts. I can borrow a scope to measure the switching freq....

                      I got a dead HD6950 on Ebay to try my luck and repair it. There were a few broken off capacitors that I already replaced.
                      Measuring the PCI-E lanes I got somewhat weird measurements, the gpu might or might not be dead.

                      If I plug the GPU in, the core heats up and I also get VCore but on two inductors that measure 16 and 60 Ohms respectively (Memory and PEX I guess) there is no voltage.
                      On one of the two buck-controllers (APW7165) the enable pin is pulled to GND and the other controller I just cannot find a datasheet for.

                      So if anyone has a datasheet or at least...

                      Is there any datasheet for nichicon RT(M) series?
                      by chth96
                      A few days ago,I destroyed one of my japanese retro game console by pluging it to 220v outlet.
                      https://www.badcaps.net/forum/troubl...e-been-blew-up

                      and I finally fixed​ this retro game console by soldering varistor and glass fuse.

                      But I noticed that When I measure voltage of PSU's 5pin connector, it is 8.80-9.07v, 5.13v,3.40-3.48v,GND,GND instead of its rated voltage of 9v 5v 3v GND GND.
