Better get a bracket: GPU sagging really does ruin your graphics card

Graphics card sagging, while once a non-issue, has become a genuine threat to their lifespan, causing them to fail much sooner than normal. As cards become more powerful, they also become much larger and heavier in design, which means they tend to sag if not supported on both sides in the PC case.

As German computer repair technician KrisFix (opens in new tab) explains (and reported on by Tom’s Hardware) when a graphics card sags as a result of this increased weight, “memory modules can lose connection with its associated solder points on the PCB.” There’s also the issue of thermal variance, caused by the daily use of the card under sag conditions.
