Corsair K95 Guide: Which Model to Buy + Hidden Value in 2025

Before buying a used Corsair K95 (typical eBay range: $60–$150), note three things: Corsair discontinued the K95 line in 2021; there are three distinct K95 variants buyers often mix up; and on the Platinum/XT models the G-keys can function as a Stream Deck. Every month ~1,900 people search “Corsair K95.” Amazon commonly lists it as currently unavailable, and many eBay listings omit the model—so buyers are surprised by differences in macro count and keycap quality.

This guide will:

• ✅ Explain the critical differences between K95 RGB (original – 18 G-keys), K95 RGB Platinum (6 G-keys), and K95 RGB Platinum XT (6 G-keys)
• ✅ Show how to use the Elgato Stream Deck integration to turn G-keys into hardware macros
• ✅ Walk through the isopropyl alcohol double-typing fix and safe alternatives
• ✅ Tell you what to buy instead if a K95 doesn’t match your needs

If you’re a video editor, streamer, or programmer needing hardware macro keys, a used K95 Platinum might be worth $60-90. If you just want RGB and aluminum, buy the K100 RGB instead.

Quick Answer

Quick answer: Buy a used K95 RGB (original) only if you find it ≤ $60 and need 18 hardware macro keys. Buy a used K95 RGB Platinum if you need 6 G-keys + Stream Deck functionality for ≤ $90. Buy the K95 RGB Platinum XT for PBT caps + standard bottom row. Otherwise buy the K100 RGB.

🔥 Which K95 Should You Buy?

Bottom line: Only the original K95 RGB (2016–2019) has 18 G-keys. Both Platinum and Platinum XT use 6 G-keys. If you don’t need the 18-key layout, prefer Platinum (for macros) or XT (for PBT/keycap modding).

⚠️ CRITICAL: The “18 G-Key” Trap

This is where most buyers get it wrong.

The Three-Model Taxonomy

Why This Matters

Important: K95 RGB Platinum has 6 G-keys, not 18 — Corsair cut the macro bank after the original release.

Other compatibility issues:

• Non-standard bottom row (RGB & Platinum) — many inexpensive keycap kits often do not include the 6.5u spacebar or odd modifiers, making full sets difficult to install
• ABS keycaps (RGB & Platinum) — develop shine/wear after 6–12 months
• Platinum XT has standard bottom row — easier to find replacement keycap sets

The smart buy:

• Original K95 RGB (18 G-keys, $60-90) = Only if you MUST have 18 macro keys — rare, aging, no Stream Deck support
• K95 RGB Platinum (6 G-keys, $60-90) = Best value for Stream Deck integration + basic macros
• K95 RGB Platinum XT (6 G-keys, $90-120) = Best if you want PBT keycaps and modding flexibility

💎 Hidden Value: The 6-Key Mini Stream Deck

Underrated feature: After Corsair acquired Elgato, firmware/iCUE updates added Stream Deck actions so K95 Platinum/XT G-keys can behave like a small Stream Deck.

The Math

• Standalone Elgato Stream Deck Mini: $79.99
• Used K95 RGB Platinum (6 G-keys + keyboard): $60-90
• Net savings vs Stream Deck Mini: $0–$20 + a full mechanical keyboard

Real-World Use Cases

Video Editors (Premiere Pro, DaVinci Resolve):

• G1 = Ripple Delete
• G2 = Add Marker
• G3 = Razor Tool
• G4 = Render In/Out
• G5-G6 = Custom shortcuts

Streamers (OBS):

• G1 = Start/Stop Recording
• G2 = Switch Scene 1
• G3 = Switch Scene 2
• G4 = Mute Mic
• G5-G6 = Discord Mute/Deafen

Programmers:

• G1 = git push
• G2 = git pull
• G3 = npm run dev
• G4 = Terminal toggle

Engineers (AutoCAD, Fusion 360):

• Map complex macros to single G-key presses
• Layer toggles
• Frequently-used commands

How to Set It Up

1. Download the latest Corsair iCUE software from corsair.com/icue
2. Go to Actions → Create → Elgato Stream Deck
3. Assign any Stream Deck action to G1-G6 keys
4. Works with OBS, Streamlabs, Discord, Spotify, Philips Hue, etc.

Note: Advanced Stream Deck actions require iCUE on Windows; on Mac/Linux use onboard hardware macros for simpler mappings.

This alone can justify buying a used K95 Platinum if you do content creation or productivity work.

🎮 Individual Model Reviews

K95 RGB (Original, 2016-2019)

Status: Very rare / aging

What It Was: The original flagship with 18 programmable G-keys arranged in 6 columns on the left side. This was THE keyboard for MMO gamers (WoW, FF14) and video editors who needed extensive macro layouts in 2016-2018.

Why You Can’t Find It: Most units are 7-9 years old now. Cherry MX switches last 50M presses, but after this long, many are failing.

Key Drawbacks:

• No Elgato Stream Deck support (no iCUE Elgato support)
• ABS keycaps with severe shine/wear
• Non-standard bottom row (hard to replace keycaps)
• High LED failure rate (estimated 50–70% for 2016 units; red LEDs usually last longest)
• Switch chatter on high-use switches (WASD, Space) — common on high-mileage units

Should You Buy It? Skip unless you find it under $60 and <30% dead LEDs.

Verdict: Skip unless under $60 with <30% dead LEDs.

K95 RGB Platinum (2017-2021) ⭐ Best Value

Status: Discontinued but most common ($60-90 used)

What Makes It Special:

• 6 G-keys (note: original had 18)
• Per-key RGB (upgrade from zone RGB on original)
• Aircraft-grade aluminum frame (survives 5+ years)
• Elgato Stream Deck integration (the main selling point)

Key Drawbacks:

1. ABS Keycaps – Develop shine after 6–12 months
2. Non-standard bottom row (6.5u spacebar) – Can’t easily replace with custom keycaps
3. Double-Typing Issue – Anecdotal ~20% users report double-typing; software or IPA fixes sometimes work
4. Not Hot-Swappable – Switches are soldered; requires soldering iron to replace
5. 20-40% LED failures after 4-6 years

Where to Buy:

• Amazon Renewed: $70-90 (90-day warranty, check seller return policy)
• eBay: $60-120 (check seller rating >98%)
• r/hardwareswap: $50-80 (best deals, no warranty)

Who Should Buy:

• Content creators needing 6 hardware macro keys
• Streamers wanting Stream Deck functionality (6 keys)
• Budget-conscious buyers under $90
• Users okay with ABS keycaps

Verdict: 8/10 – Best value if you need 6 macro keys + Stream Deck integration

K95 RGB Platinum XT (2019-2021) 🏆 Premium Used Option

Status: Discontinued but best quality ($90-120 used)

What Makes It Better:

• PBT Double-Shot keycaps — textured and far less prone to shine than ABS
• Standard bottom row – Easy to mod with custom keycap sets from Amazon
• Plush leatherette wrist rest – Huge upgrade over rubber (premium feel)
• Native Elgato Stream Deck integration

What you lose:

• Still only 6 G-keys (not 18 — same as Platinum)
• Cherry MX Speed switches only (no Brown/Red/Blue options)
• Not hot-swappable
• Two USB ports required for full RGB brightness

Key Drawbacks:

• 10-30% LED failures after 3-5 years (better than older models)
• Double-typing issue (same as Platinum)
• Most expensive used option ($90-120)

Who Should Buy:

• Buyers who want PBT keycaps and modding flexibility
• Users who only need 6 macros (not 18)
• Premium feel seekers

Verdict: 8.5/10 – Best K95 for quality, but doesn’t have the legendary 18 G-keys

🔧 Common Problems & The “Engineer’s Fixes”

Problem 1: Double-Typing / Key Chatter

Symptom: Press E once, get ee. Press Space, get double-space.

Cause: Dust/gunk buildup in Cherry MX switch contacts, or worn switch contacts after 50M+ presses.

The Isopropyl Alcohol Fix:

1. Power off and unplug keyboard
2. Remove affected keycap
3. Apply 2-3 drops of 99% isopropyl alcohol to the switch stem with a dropper (NOT 70% — needs high concentration)
4. Rapidly actuate the switch 50-100 times using normal force (avoid excessive force)
5. Let dry 2-3 hours (alcohol evaporates)
6. Test before reassembling

⚠️ Do this only on powered-off keyboard and avoid pouring alcohol onto PCB; use a dropper and treat one switch first.

Success Rate: ~50-60% (not 80% as some claim)

Software alternate: In iCUE (Device Settings → Debounce), increase debounce to 20 ms to eliminate most double-typing while keeping responsiveness acceptable.

If It Doesn’t Work:

• Switch is mechanically failed (50M+ presses reached)
• Replacement requires soldering in new switch (NOT hot-swappable)
• Or RMA if under warranty period

Problem 2: Non-Standard Bottom Row (Keycap Replacement)

Symptom: You want to buy PBT keycaps from Amazon, but they don’t fit the bottom row.

Cause: K95 RGB and Platinum use 6.5u spacebar and non-standard Ctrl/Alt/Win key sizes.

The Fix:

• Best option: Buy K95 Platinum XT instead (standard bottom row)
• Workaround: Only replace alphanumeric keys, leave bottom row stock
• Expensive option: Buy custom keycap sets specifically for non-standard layouts (~$60–$100)

Pro Tip: When buying used, ask seller: “Is this the XT model with standard bottom row?” to avoid this issue.

Problem 3: LED / RGB Lighting Failures

Symptom: 30-50% of LEDs dim, flicker, or die after 3-5 years. Red LEDs last longest, blue/green die first.

Cause: LED degradation over time (normal hardware aging).

The Fix:

• None (hardware failure, not fixable without soldering new LEDs to PCB)
• Workaround: Use single-color profiles (red only) in iCUE to hide dead zones

Negotiation rule: if >30% LEDs are dead, reduce your offer by ~30–40%.

Reality Check: When buying 2017-2020 K95 units, expect some LED deaths. Factor this into price negotiations.

Problem 4: Two USB Ports Required (Power Draw)

Symptom: RGB flickers, keyboard disconnects randomly, lighting looks dim.

Cause: K95’s LightEdge (19-zone RGB bar at top) draws too much power for single USB 2.0 port.

The Fix:

1. Plug both supplied USB connectors into your PC (one labeled “RGB/light”)
2. OR use USB 3.0 port (provides more power — single cable works)
3. OR disable LightEdge in iCUE (boring but solves disconnect issues)

Before paying: Plug both USB leads into system and test LightEdge at full-brightness rainbow profile for 30s; look for flicker.

Problem 5: Not Hot-Swappable

Symptom: You want to replace Cherry MX Speed with tactile switches, or a switch died.

Reality: K95 switches are soldered to the PCB. You cannot pull them out like modern hot-swap keyboards.

The Fix: If you plan to replace switches, budget $30–50 for a basic soldering/desoldering kit (iron + pump + solder). Repair shops typically charge $20–40 per switch.

⚔️ K95 vs K100 RGB: The Real Comparison

Verdict:

• Buy Original K95 RGB only if you absolutely need 18 G-keys and find it under $60
• Buy K95 Platinum if you need 6 G-keys + Stream Deck function under $100
• Buy K100 for everything else (better polling, warranty, one USB port, PBT keycaps)
