'It's exploding now?' — Reddit user's Zotac RTX 5090 'explodes' while playing Assassin's Creed Black Flag Resynced, and I'm starting to get worried that high-powered GPUs aren't safe

It's yet another point of concern for RTX 5090 users

Nvidia's RTX 5090 has been the subject of controversy ever since its launch, with several well-publicised cases of melting power connectors causing malfunctions — and this time, it's arguably the worst case yet.

As reported by Wccftech, a Reddit user's Zotac RTX 5090 GPU has exploded, 'five minutes' into playing the tutorial for Assassin's Creed Black Flag Resynced. Interestingly, the 16-pin power connector (often the case of the RTX 5090's woes) wasn't damaged. Instead, the user claims they heard a loud pop and crackle, followed by a cloud of smoke.

The 16-pin power connector has been blamed for several RTX 5090s melting, either due to high temperatures or connectors that aren't properly seated. It also shouldn't be a surprise that these melting complications are effectively exclusive to Nvidia's flagship GPU, since it draws a significant amount of power (575W maximum).

Instead, the PCB gold finger (the part that goes into the motherboard's PCIe slot) on the user's Zotac RTX 5090 has a visible burn mark. The cause isn't exactly clear, but speculation suggests that a crack in the circuit board may have caused the GPU to short-circuit.

Perhaps the most concerning aspect of this case is the suggestion from fellow Reddit users that the supposed crack and short circuit may be the result of GPU sag — and if that's the case, it should be a major concern for high-powered GPU users.

Plenty of modern GPUs, notably from third-party Nvidia partners, are quite chunky, which leaves little clearance to fit in smaller cases and, most importantly, not enough space to use GPU sag brackets.

Fortunately, the RTX 5080, RTX 4080, and RTX 4080 Super (which is the GPU I use) aren't cards that draw nearly as much power as the RTX 5090, so there isn't too much concern in terms of power connectors melting. However, if GPU sag can lead to a short circuit, it raises concern for any GPU that's heavier than most, especially the high-powered RTX 5090, as it's an additional issue to be wary of alongside melting connectors.

A melting or exploding GPU in this current PC hardware market is possibly the worst-case scenario, particularly for RTX 5090 users (who are seemingly most at risk), as prices are completely out of the affordable range due to the ongoing RAM crisis.

Frankly, it makes me want to steer clear of high-wattage GPUs completely (or at least undervolt them). TechRadar has contacted Nvidia for a response.
