What is Corsair K70 RGB Pro?
The Corsair K70 RGB Pro is a full-size, wired mechanical gaming keyboard. It is a direct evolution of one of the most recognisable lines in PC peripherals.
Its primary function is to deliver a high-performance typing and gaming experience. The headline specification is an 8,000Hz hyper-polling rate for ultra-responsive input.
This is complemented by a durable aluminium frame, per-key RGB backlighting, and Cherry MX mechanical switches. It is a workhorse keyboard for gamers who prioritise responsiveness and build quality, while also serving as a capable daily driver.
Corsair is an American company founded in 1994. It has become a dominant force in the PC gaming and enthusiast component market.
The K70 line has been a cornerstone of its peripheral division for nearly a decade. The K70 RGB Pro serves as its latest mainstream flagship, blending proven design with modernised internals and software support.
Who is Corsair K70 RGB Pro best for?
The K70 RGB Pro is not a keyboard for every user. Its full-size form factor, specific feature set, and price point target a particular market segment.
It provides the most value to users whose needs align with its performance-oriented engineering and reliable construction. It is less suitable for those seeking a minimalist, portable, or budget-conscious option.
- Competitive and Enthusiast Gamers: Players who want the tangible advantage of an 8,000Hz polling rate, especially in fast-paced titles like first-person shooters or fighting games.
- Users Who Value Long-Term Durability: Those who appreciate the solidity of an aluminium top plate and well-regarded Cherry MX switches over flimsy plastic keyboards.
- RGB Enthusiasts Invested in Ecosystem Synergy: Individuals who already own other Corsair iCUE-compatible products and want unified lighting control across their setup.
- Heavy Typists Who Also Game: Users who spend significant time typing but demand gaming-grade performance, and who prefer a full layout with a number pad.
Key features
8,000Hz Hyper-Polling Technology
This feature increases the speed at which the keyboard reports its input status to the computer. It goes from the standard 1,000Hz to 8,000Hz.
In practical terms, this can reduce input latency by a fraction of a millisecond. This may be perceptible in highly competitive gaming scenarios, though the difference from 1,000Hz is often negligible for casual use.
Durable Aluminium Frame
The keyboard uses a brushed aluminium alloy top plate. This provides a rigid foundation for the switches and prevents flex during intense typing or gaming sessions.
It enhances the overall premium feel and contributes significantly to long-term structural durability compared to all-plastic constructions.
Per-Key Dynamic RGB Backlighting
Each key has an individually addressable RGB LED beneath it. This allows for complex lighting patterns, animations, and static colour schemes assigned on a per-key basis through Corsair's iCUE software.
This enables functional lighting setups, like highlighting WASD keys, or purely aesthetic displays.
Cherry MX Mechanical Switches
The K70 RGB Pro uses genuine Cherry MX switches, a longstanding industry standard known for consistency and reliability. Users can typically choose between linear Red, tactile Brown, and clicky Blue variants.
This allows them to select the typing feel that best suits their preference.
Dedicated Media Controls and Volume Roller
A set of discrete buttons for play/pause, skip, and stop sits alongside a large, notched metal roller for volume adjustment. This provides immediate hardware control over media playback.
It is a convenient quality-of-life feature that avoids the need for function key combinations or software intervention during gameplay.
Corsair K70 RGB Pro pricing
The Corsair K70 RGB Pro does not have formal pricing tiers. Its cost varies based on the specific Cherry MX switch type selected and retailer promotions.
It is positioned as a premium mainstream gaming keyboard. It typically retails at a price point above budget mechanical boards but below specialised enthusiast or custom keyboards.
The value proposition hinges on how much you prioritise its core features. You are paying for the reliable aluminium build, the high-polling-rate technology, the extensive iCUE software integration, and the Corsair brand assurance.
Compared to a budget mechanical keyboard, it offers superior materials and performance. When compared to other keyboards in a similar price bracket, some competitors may offer additional features like hot-swappable switches at a similar cost.
| Keyboard Type | K70 RGB Pro | Budget Mechanical |
|---|---|---|
| Build | Aluminium frame | Plastic construction |
| Polling Rate | 8,000Hz | 1,000Hz standard |
| Customisation | Per-key RGB via iCUE | Limited or basic RGB |
What we like
- Solid build quality: The aluminium frame provides an exceptionally solid and premium typing foundation that eliminates case flex entirely.
- Maximum responsiveness: The 8,000Hz polling rate delivers maximum theoretical responsiveness for competitive gaming, even if often imperceptible.
- Convenient media controls: The dedicated media controls and oversized metal volume roller are incredibly convenient and satisfying to use daily.
- Vibrant RGB: Per-key RGB lighting is vibrant, customisable, and deeply integrated into the iCUE software ecosystem.
- Comfortable wrist rest: The inclusion of a plush, magnetic wrist rest in the box significantly improves comfort during extended sessions.
What could be better
- Limited keycap compatibility: The proprietary keycap puller and non-standard bottom-row layout make finding high-quality aftermarket keycap sets more difficult.
- Resource-heavy software: Corsair's iCUE software is powerful but can be resource-heavy, sometimes buggy, and is mandatory for full customisation.
- No sound dampening: The keyboard lacks internal sound dampening, which can lead to a slightly hollow or pingy sound profile, especially with linear Red switches.
- No hot-swap sockets: At its standard retail price, the lack of hot-swappable switch sockets feels like a missed opportunity for future-proofing.
Corsair K70 RGB Pro verdict
The K70 RGB Pro is a confident, conservative evolution of a classic. It refines a proven formula with a meaningful technical upgrade and maintains its signature build quality.
The Corsair K70 RGB Pro excels as a dependable, high-performance tool for serious gamers and users who appreciate tangible durability. The typing experience is well-regarded, the media controls are praised, and the overall package feels built to last for years of heavy use.
However, this focus on established strengths means it lacks some modern customisation features becoming common in the segment. The non-standard keycap layout and absence of hot-swap sockets will disappoint tinkerers, and the requirement to run iCUE software will frustrate those who prefer plug-and-play simplicity.
The recommendation for the K70 RGB Pro is strongest for gamers who are already invested in the Corsair ecosystem. It suits those who explicitly want the 8,000Hz polling rate and who prioritise a rock-solid, full-featured keyboard over modularity.
Users who value a quieter typing experience, want easy keycap customisation, or are on a tighter budget should carefully consider alternatives that may better suit those specific needs.
