Corsair K70 RGB TKL: Specs, Features, Pros & Cons
This review measures the Corsair K70 RGB TKL against the full 34-spec sheet we track for keyboards, comparing it like for like with the 74 other models in our database. It earns a VS Score of 36 out of 100 — the weighted result of every verified specification measured against the class average.
On the spec sheet it is strongest in performance and weakest in connectivity. Its clearest single advantage over the class average: 4,316.67 Hz more polling rate — 8,000 Hz vs 3,683.33 Hz (avg). None of our retail partners currently lists the Corsair K70 RGB TKL, so availability may be limited; a missing price never affects the VS Score. A transparency note: this spec sheet is 68% complete. Anything unverified shows as Unknown and is left out of the score — we never estimate a missing value.

Editor’s note
The K70 RGB TKL is a few years old now, and that turns out to be the most useful thing to know about it — not because it has aged badly, but because it is still sold alongside newer boards at a much lower price.
It was built for tournaments and it shows. The standout feature is the physical tournament switch on the back: flip it and the board drops to static lighting and locks out macros, so nothing you configured at home can fire at the wrong moment. It is a hardware switch, not a software mode, which is exactly why competitors trust it. The USB-C cable is detachable with a latch, and the aluminium frame and 900 g weight survive being carried around.
This particular version uses Cherry MX Speed Silver switches, and they deserve a warning. At 1.2 mm the actuation is extremely shallow — excellent for fast repeated inputs, but genuinely typo-prone if you rest your fingers on the keys while writing. Corsair sold the same board with MX Red, MX Silent and its own OPX optical switches, so check the switch line on any listing. The PBT double-shot keycaps are 1.5 mm thick and will not go shiny.
Where it shows its age is acoustics and flexibility. There is no sound-dampening foam, so it sounds harder and more hollow than the foam-stuffed boards Corsair sells today, and the switches are soldered — no hot-swapping. There is no wrist rest in the box and no USB passthrough.
A buying note: Amazon's search results are dominated by the K70 CORE TKL, which is a different and later keyboard. Match the full name.
Buy it as a durable, tournament-ready board at a discount. Skip it if you care about typing sound or want to change switches.
Specifications
Quality bars are generated automatically against 74 other keyboards.
Switches & typing
The key switch technology; later types are generally more responsive.
The specific switch used (e.g. Cherry MX Red).
The force needed to register a key; lower is lighter to type on.
Swap switches without soldering.
Registers every simultaneous keypress.
Set the actuation point per key (analog / Hall-effect boards).
Keys report their travel depth for variable gamepad-style input and multi-stage actions.
Performance
How often the keyboard reports input; higher can reduce latency.
End-to-end keypress latency over a wired connection; lower is better.
End-to-end keypress latency over the fastest wireless mode; lower is better.
Resets a key dynamically as it moves, enabling faster repeated inputs.
Layout & size
The keyboard size and layout.
The number of keys.
The overall width.
The overall depth.
The front case height without keycaps; lower boards can reduce wrist extension.
The keyboard's weight.
Connectivity
The supported connection types.
How many paired devices it can switch between.
Battery life for wireless models.
The rated capacity of the internal battery.
A built-in USB port for other devices.
Build & sound
Keycap plastic; PBT resists shine and wear better than ABS.
The case material (e.g. aluminium, ABS plastic).
The switch plate material, which influences stiffness and typing sound.
How larger keys are stabilised (e.g. screw-in PCB or plate-mounted).
The plate / PCB mounting style (e.g. gasket mount).
Internal foam or dampening for a quieter, fuller sound.
The per-key lighting.
Features
Remap keys and record macros.
Dedicated volume and playback controls.
A control knob for volume or custom actions.
Stores layouts on the board itself.
Companion configuration software (e.g. VIA / QMK).
How the VS Score works — and what it can’t tell you
Every measurable spec is scored against the average of all the keyboards we track: matching the class average scores 50, clearly beating it climbs towards 100, and each spec counts according to an editorial weight that reflects real-world impact — a battery-capacity gap moves the score far more than a colour-options list. The quality bars on the spec cards above show where this model sits inside the full range for its class, and the overall VS Score rolls every weighted result into one number.
Unknown values are never estimated. A spec this product doesn’t report simply drops out of its scoring — it isn’t penalised with a guess — but a thinner spec sheet does mean a score built on fewer data points, which is why completeness is disclosed under About this data.
Most importantly: a spec-sheet lead is not the same as a better product. Megapixels, gigahertz and benchmark points describe capacity, not experience — image processing, software optimisation, thermals, haptics and ergonomics decide how a device actually feels, and no table captures reliability or long-term support quality. Treat the VS Score as a structured summary of what can be measured, not a substitute for your own priorities.
About this data
- Specifications are compiled from each manufacturer’s official spec sheet, cross-checked against trusted specification databases, and normalised into one schema so identical things are compared identically.
- Specifications last verified August 8, 2026.
- Data completeness: 23 of the 34 specs in this category are verified (68%). Anything we could not verify is shown as Unknown — never estimated — and is excluded from the score.
- Prices and availability come from live retailer feeds via our shopping partners and refresh throughout the day; a missing price means no partner currently lists the product, not that it is discontinued.
- Want the full picture? Our editorial guidelines explain how we research products, weight the scores and stay independent.

The bottom line
The Corsair K70 RGB TKL earns a VS Score of 36, trailing most of the 75 keyboards we compare here, at least on the spec sheet. It stands out for 4,316.67 Hz more polling rate, has n-key rollover and has onboard profiles. Just be aware of 0.96 less connection and no hot-swappable before you buy. Weigh those trade-offs against what matters most to you.
The VS Score is generated automatically from the weighted specifications above, measured against all other keyboards in our database. Treat it as a shortlisting guide — not a substitute for your own priorities.
