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... -
Hello,
I am new to repairing computer electronics, so excuse any mistakes I make.
A friend of mine had a broken graphics card (MSI Radeon RX 5700 XT MECH OC) and gave it to me. It does not power on or show any signs of life.
I identified what looks like the remains of a blown capacitor at the bottom of the board (see picture).
I wanted to replace the capacitor, but I have two questions:- Does this repair have a chance of working? or is a blown capacitor a sign something else is wrong?
- How do I determine the rating/value of this capacitor? or something

Hi everyone,
I'm new to this, so I apologize for not providing enough details. Is there anything else I need to mention? I'm trying to learn more about electronic/board repairs and hopefully fix my own.
The only visible issue on my board is one capacitor, CP813, which appears to be labeled R 221k 2kV (possibly obsolete to B 221k 2kV now). My monitor hadn't shown any prior issues, although it is a few years old. Just before the capacitor popped, there was a high-pitched squeal for 2–3 seconds.
I don't see any other visible damage anywhere else on the board.... -
Hi all, Acer Nitro 5 - GH51M LA-K862P Rev 1A motherboard. I went through all the troubleshooting steps but couldnt find a short on any coils. By chance, ended up finding a blown capacitor PCZ49 which is suppose to be 2.2uF. I can see plenty of 2.2uF in the same +5VALW line which will all parallel up anyway - do you guys think it is critical for this cap to be replaced or i can get away without one?... -
25V 470uF? Any help would be appreciated! This was in an Adam A7X speaker. I replaced with a different uF and voltage closest to the values I thought because it is all I had in stock. It restored the speaker to working condition but it is certainly not what I needed to do as it is putting out less volume than its sister speaker which presumably no issues....
Working...
