Which CORSAIR Gaming Keyboard Should You Buy? A Comparison of Their Top 3 Models
CORSAIR's three flagship gaming keyboards each solve different problems: the K55 RGB Pro delivers RGB lighting and programmability on a budget, the Raptor K40 prioritises speed and responsiveness for competitive play, and the K66 Cherry MX Red offers mechanical precision for typists and esports players who demand tactile feedback. Your choice depends on whether you value affordability, performance, or mechanical quality.

Top Picks
K55 RGB Pro Gaming Keyboard — £59.99
Best for budget-conscious gamers who want RGB lighting without mechanical switches. The K55 RGB Pro uses pressure-activated membrane switches (not mechanical), making it quieter and cheaper than alternatives. It includes 1.8 million RGB colour options, six programmable macro keys, and a detachable USB cable. The compact design fits smaller desks, and the £59.99 price point makes it CORSAIR's entry-level option. Verdict: best value for casual gaming and office use.
Raptor K40 Gaming Keyboard — £79.99
Best for competitive esports players prioritising response speed. The Raptor K40 strips away RGB flourish to focus on performance: it features optical switches with a sub-1ms response time, making it noticeably faster than membrane alternatives. It's lightweight, portable, and designed for tournament play where milliseconds matter. The 40% compact layout reduces hand travel distance, ideal for fast-paced shooters and MOBAs. Verdict: fastest keyboard in CORSAIR's current range.
K66 Mechanical Gaming Keyboard — Cherry MX Red — £69.99
Best for typists and mechanical enthusiasts who value tactile feedback and build quality. The K66 features genuine Cherry MX Red switches—widely considered the gold standard for gaming and writing—rated for 50 million keystrokes. The full-size layout includes dedicated macro keys, Cherry MX switch stability, and a 3.5mm audio jack for headset connection. At £69.99, it sits between the K55 and Raptor, offering mechanical durability without the price premium of higher-end boards. Verdict: best all-rounder for balanced gaming and productivity.

What to Look For
- Switch type: Membrane switches (K55) are quiet and cheap; mechanical switches (K66) last longer and feel better; optical switches (Raptor K40) offer the fastest response times. Choose based on whether you prioritise cost, durability, or speed.
- Keyboard size: The Raptor K40's 40% compact layout saves desk space but removes the numpad; the K55 and K66 are full-size, suited for gaming and productivity. Compact boards suit esports players; full-size boards suit office work.
- RGB customisation: All three include programmable RGB, but the K55 emphasises visual effects with 1.8 million colours. The Raptor K40 removes RGB entirely, cutting cost and visual distraction.
- Durability rating: The K66 Cherry MX switches are rated for 50 million keystrokes, roughly 15 years of heavy use. The K55's membrane switches last 5–10 million keystrokes. The Raptor K40's optical switches are rated for 100 million keystrokes—the longest-lasting option.
The Bottom Line
The K55 RGB Pro at £59.99 is CORSAIR's best value keyboard for most gamers, offering RGB lighting and programmability without breaking the bank. If you play competitively and need sub-1ms response times, the Raptor K40 (£79.99) is worth the extra £20. For mechanical switch enthusiasts and typists who want genuine Cherry MX Red quality at a fair price, the K66 (£69.99) delivers durability and tactile feedback unmatched by membrane boards.
Frequently Asked Questions
Is CORSAIR good value for money?
Yes. CORSAIR's three gaming keyboards range from £59.99 to £79.99, positioning them competitively against Razer, SteelSeries, and Logitech at the same price point. The K55 RGB Pro specifically undercuts rivals by offering RGB lighting in a budget keyboard, while the K66 Cherry MX Red delivers mechanical quality for less than premium gaming brands charge for equivalent switches.
What's the difference between the K55 and K66?
The K55 uses pressure-activated membrane switches, making it quieter, cheaper (£59.99), and lighter. The K66 uses mechanical Cherry MX Red switches, making it more durable (50 million keystroke rating), more tactile, and better for prolonged typing sessions. If you primarily game casually, the K55 suffices; if you game competitively or type frequently, the K66's mechanical switches justify the £10 extra.
Should I buy the Raptor K40 or the K66?
Choose the Raptor K40 (£79.99) if speed is your priority and you play competitive esports—its sub-1ms optical switches and compact layout are tournament-grade. Choose the K66 (£69.99) if you want a versatile all-rounder for gaming and office work. The Raptor sacrifices the numpad and programmable macros for pure responsiveness; the K66 keeps all features and adds mechanical tactility at a lower price.
Are mechanical switches worth the extra cost?
Yes, if you use your keyboard for more than gaming. Mechanical switches (K66) feel better during long typing sessions, last longer (50 million vs 5–10 million keystrokes), and give consistent feedback. For casual gamers who use their keyboard sparingly, the membrane K55 offers adequate performance. For esports players, optical switches (Raptor K40) beat mechanical on speed; for everyone else, mechanical quality justifies the price difference.
