| Damaged Steam Controller puck and Pixel Watch 3 strap. |
When Valve released the updated Steam Controller alongside the Steam Deck, many gamers were thrilled to see the return of the beloved—and often misunderstood—peripheral. The new wireless puck, which enables a 2.4 GHz connection and doubles as a magnetic charging adapter, was hailed as a clever piece of engineering. But as one Reddit user discovered, those exposed metal pins on the puck can create a real-world hazard you probably never thought about.
In a cautionary post shared on the SteamController subreddit, user ‘Toikka’ detailed a frightening moment involving the Steam Controller puck, a Pixel Watch 3, and a few seconds of genuine panic. No one was injured, and the damage turned out to be mostly cosmetic, but the incident raises legitimate questions about the puck’s always-live electrical contacts.
What Actually Happened?
According to Toikka’s post, the Steam Controller puck was sitting on a desk while its corresponding smartwatch—a Google Pixel Watch 3—was resting on its own charger nearby. The two devices accidentally touched. More specifically, the exposed pins on the puck came into contact with the metal strap of the smartwatch.
That contact created a short circuit. Almost immediately, the puck started to sizzle. The metal watch strap began heating up rapidly, leaving minor burn marks on both the strap and the puck’s casing. “I noticed a faint smell and then saw a small wisp of smoke,” Toikka wrote. Fortunately, the user reacted quickly, separated the devices, and prevented any flames from igniting. Both the Steam Controller puck and the Pixel Watch 3 continued to function normally afterward—a lucky outcome given the potential for a small electrical fire.
Why Did This Happen?
The core issue seems to be that the puck’s charging pins remain live even when the puck isn’t actively connected to a controller or a power source. In normal use, those pins only carry current when the puck is magnetically attached to the Steam Controller for charging. But if the puck is sitting loose on a desk—still holding a residual charge or maintaining some level of active circuitry—any conductive material that bridges the wrong pins can cause a short.
In this case, the metal watch strap acted as the conductor. It’s a plausible accident: both devices are often found on desks, nightstands, or entertainment centers. Gamers frequently swap between playing and wearing a smartwatch, and the compact size of the puck makes it easy to overlook.
Valve Is Investigating
The good news is that Valve isn’t ignoring the incident. Toikka shared that they’ve been in contact with the Steam Hardware team, which is now actively looking into the issue. The damaged puck and watch strap (or at least the affected items) are being shipped to Valve for analysis. As a gesture of goodwill, the company is also sending the user a replacement puck.
It’s worth noting that this appears to be an isolated report. There’s no widespread pattern of Steam Controller pucks causing shorts or fires. Still, the fact that the pins remain energized when not in use strikes some commenters as a design oversight. One Reddit user wrote, “This is a classic case of a product being engineered for convenience without fully considering edge cases. Those pins shouldn’t be hot unless they’re actively charging.”
Could a Firmware Update Fix This?
Possibly. If the puck’s power delivery is controlled by firmware—meaning the device can detect whether it’s properly seated against a controller before sending current—Valve might be able to patch the behavior. A future update could ensure the pins are completely de-energized unless the magnetic connection is confirmed. However, if the circuitry is purely hardware-based, a fix might require a revised physical design in future production batches.
For now, Valve hasn’t issued an official public statement beyond their communication with Toikka. Given the company’s track record of supporting the Steam Controller and Steam Deck ecosystem with regular updates, it wouldn’t be surprising to see a patch or a quiet revision down the line.
What You Can Do to Stay Safe
While the odds of this happening to you are extremely low, a few simple precautions can eliminate the risk entirely:
- Don’t leave the puck loose on a cluttered desk. Store it in a drawer, a small tray, or attached to the controller when not in use.
- Be mindful of metal objects near the puck. Watch straps, paper clips, keys, coins, or even aluminum laptop bodies could potentially cause a short.
- If you notice heat or a sizzling sound, disconnect power immediately. Unplug the puck from any USB source and move it away from flammable materials.
- Consider covering the pins with a small piece of non-conductive tape (like electrical tape) if you frequently transport the puck loosely in a bag.
The Bottom Line
The Steam Controller remains a fantastic piece of hardware, and the puck’s wireless and charging features are genuinely useful. But this incident is a reminder that even well-designed products can have unexpected failure modes. It’s not a reason to panic or return your controller—just a reason to be a little more aware of where you leave that small, powerful puck.
As Toikka put it at the end of their post: “I’m not angry at Valve. Shit happens. But I wanted people to know so they don’t learn the same way I did.”
With any luck, Valve’s investigation will lead to a quiet fix, and this will remain a one-off cautionary tale rather than the start of a trend. Until then, maybe give your desk a quick once-over—and keep that puck away from your watch.
