The Steam Deck has changed the landscape for handheld PC gaming, delivering impressive performance in a portable package. Still, many owners dream of even more power—running AAA titles at ultra settings, enabling smoother 4K gameplay, or trying ray tracing, all of which are beyond the built-in GPU’s usual reach. Naturally, questions like "Does the Steam Deck support external GPUs?" or "Can I use an eGPU for high-end gaming on my Steam Deck?" are common among enthusiasts aiming for a next-level experience.
