Capacitor detached from PCB – RTX 2070 Super Founders Edition
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 load
- Furmark 2 stress test ran ~20 minutes, stable, slightly higher score than before cleaning
- Temps: 86 °C core / 99 °C hotspot
- However, the "GeForce RTX" side LED did not light up
After shutdown and disassembly to verify fan/LED connector seating, I noticed the capacitor on the desk.
I have not powered the card on again since then.
My assumption:
Since only the LED stopped working, this capacitor may belong to the LED/boost circuit.
However, I cannot identify the exact pad location or value.
Attempts so far:
- Compared PCB photos with images from TechPowerUp (and my own board), but could not identify missing component
- Aware that the 2070 Super FE PCB shares layout similarities with the 2080 FE
Request:
Assistance in:
1. Identifying the capacitor type/specs
2. Locating the exact position on the PCB where it belongs
I have little experience with board-level electronics, schematics, or boardview tools.
Any guidance would be greatly appreciated.
Thanks in advance.
