    Capacitor detached from PCB – RTX 2070 Super Founders Edition
    by MORETTIGIAN
    Title:
    Capacitor detached from PCB – RTX 2070 Super Founders Edition

    Description:
    During maintenance on an RTX 2070 SUPER Founders Edition, I found a capacitor lying on my desk after reassembly.
    I did not notice it detaching, so I am unsure of its original location on the PCB.

    Procedure performed:
    - Removed backplate
    - Cleaned heatsink and PCB with isopropyl alcohol + soft ESD brush
    - Reapplied thermal compound
    - Reassembled card

    Observed behavior after reassembly:
    - GPU powers on and operates normally under...

    RTX 3080 FE Identifying capacitor
    by Prolog
    Hi people, I hope this is the correct spot to post this, I'm new to the forum.

    I have an RTX 3080 Founders Edition which has a burnt up capacitor (it was in parallel with another capacitor which appears damaged too), so I am hoping to be able to identify the capacitor values and order replacements.

    I hope these photos make it clear which component I am referring to:
    (yes, the soldering is a bit botched from removing the blown one, I know)

    I have found the board schematic (attached), but there does not seem to be a boardview available. I have never...

    Dick Smith Q-1760 linear power supply filter capacitor question
    by Agent24
    I have acquired a used Dick Smith Q-1760 power supply - although the OEM is Manson Industrial
    It has at least one problem.

    The voltage control potentiometer VR2, 50K is faulty - going high resistance / open circuit in the CCW end and leading to the output voltage jumping around.
    I have already ordered a replacement potentiometer, so that's not an issue.

    Now, I want to replace all three electrolytics on the PCB as they are CapXon and I don't trust them so much, I will replace them with something better while I've got the thing apart anyway.
    All are CapXon...

    If I replace with inferior capacitor, Is it No harm to other IC components at all?
    by chth96
    I replaced some capacitor which is located on optical pickup pcb which is shown in the table below(PCB #2).Because it have been out of order.
    Now,It works very well,But I just have found that all caps (6svpc100my and other part number as well) ,which is shown in the table below, has ultra-high ripple current spec.
    It is not able to obtain any capacitor which can be a substitute for this ultra-high ripple current nichicon capacitor.
    So I replaced it with samxon and rubycon's general capacitor(GP,YXA series).
    I know that these capacitor will not last as long as nichicon capacitor...

    How can I test non-polarized capacitor?
    by chth96
    I desoldered samwha NF capacitor(50v 5.6uf) from PCB circuit of 29inch CRT TV which have symptoms of no display after I heard sound of inrush of current to TV whenever I switch on this television.
    I measured ESR value of this non-polarized capacitor(samwha NF capacitor 50v 5.6uf) by means of MESR-100 ESR meter and It displayed 0.3 ohm

    And When I measured its capacitance with digital multimeter and LCR-T4 Mega328 meter, It displayed 10uf from DMM and 8uf from LCR-T4 meter.
    I found catalogue of samwha capacitor(samwha-catalogue_3.pdf file), which is attached to this thread,...
