    please help identify IC, repairing supermicropPSU

    Hello,
    Please help identify this IC with top markings: EZDQ 324 MRC129. It has an ST logo also. This is from the Supermicro PSU usually used for bitcoin mining. Thanks all

      Hi.

      Maybe Amplificator operational, LM324. Check pin 11 to GND and Pin 4 for VCC.

          seconded,
          LM324 quad op-amp.

          btw, it may be better to replace it with LM224 if it's failed.
          LM224 is the higher temperature version.

              Trying to identify two SOT23 SMD codes, devices from mining PSU
              by dicky96
              Hi guys
              Does anyone know what these two components are?

              First one is SOT23 marked LPS 6CB
              The other one is SOT23-6 marked S43BbbA

              TIA

              identify capacitor for MacBook Pro with rare logic board 820-02037-06
              by devsigner
              Hi

              While messing around with my MacBook Pro, I stupidly pinged off a very small surface mounted component that I’m now trying to identify.
              resistance tests show a rising resistance value, indicating a capacitor.

              The laptop boots up and runs, however I'm choosing not to use it until I get it fixed.

              i can’t see any markings on the capacitor at 10x magnification using a professional jewler's loop.

              It seems like there's some damage to the capacitor - one side doesn't have "shiny bits" - can you tell I don't do this for a living!...

              DVR HIKVISION DS-7208HWI-E1/A BOARD DS-80104 REV 2.2 help identify burnt components
              by thesame
              Hy guys , i have a DVR board DS-80104 REV 2.2 that was powered wrong, i have some smds on the board that are blown and i can't identify them , maybe if someone has this board somehow and we can identify the smds', i have searched online and i can't find a schematic.
              The smds are SOT-23-6 , one of them i think it has the marking ADJF since i found another one on the board with this marking , but the other one it seems that it starts with AG or it looks like. I would really apreciate if someone could help me identify those IC's .

              Lenovo Legion 7 - Help Identify IC
              by silver60618
              Hi gang, its a long shot, but working on Lenovo Legion Pro 7 motherboard NM-F091, and trying to identify this component near GPU with marking "eHFQH" that is burned and shorting the board. Looks like power management IC

              I couldnt find any schematic or boardview. The CPU side also has same chip. Any way to identify this chip? or take measurements from the good chip to determine what it is?

              Any help would be appreciated...

              How can I identify varistor which have been blew up?
              by chth96
              I mistakely pluged 100v japanese retro game console to 220v outlet.
              So It seems that glass fuse and varistor have been blew up.
              I can identify that voltage and ampere value of glass fuse(250V LF 1.6A),but It is impossible to identify varistor type in my sega saturn PSU(YAMAHA 35M07U XR258)
              Is there any way to identify varistor type in my sega saturn PSU?
              Any reply would be appreciated.


              EDIT:
              It seems that I finally found out what type this black varistor is. It is Panasonic ERZV05D221 “ZNR” Transient/Surge Absorbers (Type D) Varistor Voltage...
