Best Steam Deck Accessories (2026): The Ones Worth Actually Buying

What Actually Matters, in Order

Most "best Steam Deck accessories" lists run to fifteen or twenty items. In practice, three of them solve real, common problems, and everything after that is personal preference dressed up as necessity. Here's the order that actually matters, starting with the one every owner needs regardless of how they use the device.

1. Storage: Samsung PRO Plus 512GB microSD

The Deck's internal storage fills up fast once you're past two or three modern titles, and a microSD card is the only realistic fix. The Samsung PRO Plus 512GB has become the default recommendation for a specific reason: rated speeds of up to 180MB/s read and 130MB/s write translate into real-world results, not just a good spec sheet — testers loading Elden Ring and Cyberpunk 2077 off the card reported load times close to internal storage, with no texture pop-in during play.

512GB is the practical sweet spot: enough for 5-6 large AAA titles or 20-30 indie games without paying the premium jump to 1TB. It costs roughly 50-70% more than budget 512GB cards, which is a real gap, not a rounding error — but the performance difference shows up specifically in load times and texture streaming, which is exactly where a cheap card bottlenecks a handheld.

2. Protection: A Hard Case and a Screen Protector

A carrying case and a tempered-glass screen protector solve the two damage scenarios that actually happen: drops in a bag, and scratches from pocket lint or a table surface. We break down which case is actually worth it separately — the short version is that a dedicated accessories pouch for the dock and charging cable matters more than raw protection alone.

Tempered glass over a film protector is worth the small price difference; film scratches faster and dulls the screen's clarity more noticeably than glass does over the same few months.

3. Docking: See Our Separate Guide

If you're setting up the Deck as a TV or desk console rather than carrying it, the dock matters more than anything on this list — but it's enough of its own decision that it gets its own breakdown rather than a single entry here.

What to Skip (For Now)

Thumbstick grip caps, RGB accessories, and multi-device stands solve smaller, more personal annoyances — worth adding later if a specific complaint comes up, not worth buying as part of a starter kit. The essentials above cover the problems nearly every owner actually runs into.

The Verdict

For a first round of accessories, the Samsung PRO Plus 512GB, a hard case, and a tempered-glass screen protector cover the overwhelming majority of what goes wrong with an unaccessorized Steam Deck — at a combined cost well under $150. 8.5/10 for this trio as a starter kit; everything past it is optional.
