What Do You Need to Stream on Twitch?

Most 'what do you need' lists dump forty items on you. This one is priority-ordered, because setup money and attention are finite and almost everyone spends them backwards: upgrading the camera while their audio is unintelligible. Here is the exact list, in the order it actually improves your stream — the minimum first, then the three upgrades that matter, then the traps.
The true minimum: free and already in your house
You need four things to go live on Twitch today: a Twitch account with two-factor enabled (required for streaming), a device that runs OBS Studio (free; any computer from roughly the last eight years handles 720p), an internet connection with at least ~6 Mbps upload for a stable 720p30 stream, and any microphone — including the one built into your headset or laptop. That is the whole minimum. Everything else is improvement, not requirement.
Enable 2FA in your Twitch security settings first — without it the stream key stays locked. Then in OBS: add your camera or display source, paste your stream key from the Twitch dashboard, set bitrate to 3,000–4,000 kbps (720p30) and you're live. The entire technical gap between 'I want to stream' and 'I am streaming' is about ninety minutes including download time.
The three upgrades that matter, in order
First: audio. A $50–$100 USB microphone (the usual beginner picks: a decent cardioid USB condenser or a quality headset mic) is the single largest quality jump per dollar in all of streaming. Viewers forgive pixelated video; they leave over bad audio in under a minute. Fix echo and background noise before you spend on anything visual — soft furnishings, a mic arm, and noise-gate settings in OBS are free.
Second: lighting. A $20 ring light or a desk lamp bounced off a wall outperforms any webcam upgrade, because sensors need light more than they need resolution. Third: camera — a 1080p webcam once audio and lighting are solved. Notice what's missing: capture cards, green screens, stream decks, second monitors. Those are convenience tools for specific content types, not requirements; each is a later decision, not a beginner purchase.
The bandwidth rule almost everyone violates
Your stream bitrate should stay under roughly 60% of your upload speed, measured wired, at the time you actually stream. If your plan says 100 Mbps down, that tells you nothing — run a speed test at 8pm on a weekend and look at upload. A stream at 4,000 kbps on a connection that uploads 5 Mbps will stutter during prime time no matter how good your PC is.
Wi-Fi is the other silent killer. Ethernet from router to streaming machine eliminates the single largest source of dropped frames; if that's physically impossible, powerline adapters or a good mesh node near the desk are the fallback. 'My game runs fine but the stream freezes' is almost always network, not hardware.
The beginner purchase traps
Traps, ranked by money wasted: the expensive camera bought before audio is fixed (it just produces sharper bad audio); the capture card bought to stream console games when the Twitch or console-native broadcast apps would have done the job for free; the green screen that fights your room lighting for weeks (a tidy background and good light beat chroma key at beginner budgets); and the stream deck, which automates scenes you haven't learned to run manually yet.
The test for every purchase: does it fix a problem a viewer has actually complained about? Buy in that order and you'll have a professional-feeling setup for under $200 total — and more importantly, you'll have spent your setup phase streaming, which is the only practice that matters.
Frequently asked questions
Can you stream on Twitch from a phone?
Yes — the Twitch mobile app can broadcast directly from your phone camera (IRL and Just Chatting categories run on it constantly). TikTok LIVE is phone-native. For Twitch gameplay from a console, the console's own broadcast feature or the native apps work without a capture card. A PC with OBS becomes necessary when you want scenes, overlays, and multi-source layouts — not to go live in the first place.
How good does your PC need to be to stream?
Less than the marketing suggests. Streaming at 720p30 with OBS software encoding needs a mid-range CPU from the last several years; a modern gaming GPU can hardware-encode (NVENC/AMF) at 1080p60 with barely any performance cost. If your computer plays the game you want to stream comfortably offline, it almost certainly streams it — test with OBS's built-in stats overlay before spending on hardware.
Do you need a capture card to stream on Twitch?
Only to bring external video into a PC setup — a console, a second computer, a camera with HDMI out. If you stream from the PC itself, no capture card is involved at all, and console streamers can broadcast natively without one. Treat it as a tool for a specific source, not a streaming requirement.
