K65 Plus Wireless vs MX Keys S: Compact Mechanical or Full-Size Scissor Keys?

Choose K65 Plus Wireless if you want a narrower desk layout and replaceable mechanical switches, and can give up the built-in number pad. Choose MX Keys S if you prefer low-profile scissor keys and use a full numeric and navigation layout. These are layout and control choices, not typing-speed or gaming-performance rankings.

The buying question

Is a compact mechanical keyboard with switch customization a better fit for your routine, or do you need a number pad and low-profile scissor keys?

K65 Plus trades the number pad and some dedicated navigation keys for a narrower mechanical board with replaceable switches and a dial. MX Keys S keeps the full-size layout and low-profile scissor mechanism.

Quick verdict

When to skip: Skip K65 Plus if an integrated number pad is essential. Skip MX Keys S if its 430.2 mm width exceeds your available keyboard space.
When the recommendation changes
  • A built-in numeric keypad is essential to your daily input.
  • Insert and End shortcuts would interrupt a routine that relies on dedicated keys.
  • Your work computer restricts the customization software required by a feature you want.

The differences that matter

Key Layout And Desk Space

Corsair K65 Plus Wireless (Original Midnight Grey)

75% layout without an integrated number pad, retaining arrow and function keys. Corsair lists a 320 mm-wide original Black/Gray board.[1, 2]

Logitech MX Keys S (Graphite)

Full-size US layout with an integrated number pad and dedicated navigation cluster. Logitech lists a 430.2 mm width.[4]

What this changes: Choose K65 Plus when you want a narrower keyboard and can use the top number row. Choose MX Keys S when a built-in number pad matters more than the extra width.[1, 2, 4]

The better fit depends on your priorities

Switch Mechanism And Customization

Corsair K65 Plus Wireless (Original Midnight Grey)

Pre-lubricated MLX Red linear mechanical switches with 5-pin hot-swap compatibility, plus a rotary dial.[1, 2]

Logitech MX Keys S (Graphite)

Low-profile scissor keys, with media/function controls and software shortcuts through Options+.[4, 5, 6]

What this changes: K65 Plus fits a preference for mechanical keys and changing compatible switches. MX Keys S fits a preference for low-profile scissor keys. Neither mechanism establishes faster, quieter or more comfortable typing.[1, 2, 4, 5, 6]

The better fit depends on your priorities

Best for your routine

Frequent spreadsheet or numeric entry using a dedicated keypad

Best fit: Logitech MX Keys S (Graphite)

Based on listed features, not comparative testing.

MX Keys S keeps the number pad in the keyboard. Accept its wider footprint rather than planning around the top number row or a separate accessory.

A smaller keyboard footprint with mechanical-switch customization

Best fit: Corsair K65 Plus Wireless (Original Midnight Grey)

Based on listed features, not comparative testing.

K65 Plus combines the 75% layout with compatible hot-swappable switches. Its smaller layout asks you to accept no number pad and some Fn navigation shortcuts.

A preference for low-profile scissor keys

Best fit: Logitech MX Keys S (Graphite)

Based on listed features, not comparative testing.

MX Keys S supplies that key mechanism. Choose it because you prefer that design, without assuming it improves comfort or typing accuracy for everyone.

Value and trade-offs

One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.

Whichever costs more should earn the difference through a layout and key mechanism you will use. A dial or hot-swappable switches have little value if you will leave them unused; a number pad earns its desk space only if your routine needs it.

There is not enough verified price history here for a buy-now or wait recommendation.

Limitations

  • This comparison covers original NA K65 Plus CH-91D401L-NA and US Graphite MX Keys S 920-011558. Corsair Mac, tactile and other special editions and Logitech Mini/Mac bundles are separate configurations.
  • Published widths describe the keyboards, not an entire desk setup with separate number pads or other accessories.
  • No matched testing here establishes a typing-speed, noise, latency, reliability or comfort winner. Replacing switches is a customization option, not a proven lifespan advantage.
  • Check the exact software feature and connection mode you need; this comparison does not promise identical customization in every mode.

Questions shoppers ask

What navigation adjustment does the smaller K65 Plus require?

It keeps arrow and function keys, but its Windows map puts Insert on Fn+[ and End on Fn+]. MX Keys S has dedicated Insert and End keys. If those are part of your editing routine, consider the extra key combinations before prioritizing width.

Does connecting the cable make either keyboard wired?

K65 Plus switches to wired USB input with the cable connected and its mode switch set to Off. In its wireless switch positions, the cable only charges while input stays wireless. MX Keys S uses Bluetooth or Bolt for input and USB-C for charging.

Will I need software to use their extra controls?

The guides document built-in shortcuts, including Corsair dial-mode selection and Logitech’s Fn+Esc media/F-key toggle. Corsair uses iCUE for software-controlled customization; Logitech’s Smart Actions and additional settings use Options+. Check whether your computer permits the needed Windows or Mac app.
