Black compact gaming keyboard with RGB lightbar and double-shot PBT keycaps

Logitech

Logitech G512 X 75 920-013926 gaming keyboard

SKU CH-Q00J-2YC59 MPN 920-013926

A 75% hot-swappable keyboard with 39 TMR analog keys, 0.1–4.0 mm actuation, Rapid Trigger and 8K polling

Size 75%

Option Tactile

  • Dual swap magnetic and mechanical switches for versatile feel
  • TMR analog sensors on 39 keys deliver high‑resolution precision
  • Custom actuation 0.1‑4.0 mm with rapid trigger for instant re‑actuation
  • 8K polling rate at 0.125 ms response for near‑zero latency
  • Gasket mount with 44 % recycled plastic and double‑shot PBT keycaps

Dual-swap switch versatility

The G512 X 75 combines magnetic analog and mechanical switches in one keyboard. Thirty-nine dedicated TMR beds accept the included Gateron K20 analog switches for high-resolution input. A silicone gasket mount and double-shot PBT keycaps provide a cushioned feel and long-lasting durability. Up to 44 percent certified recycled plastic is used in the construction.

Wired connectivity and 8K polling

A wired USB connection delivers toggleable 1K and 8K report rates with a 0.125 ms response time. LIGHTSYNC RGB backlighting offers 16.8 million colours across the lightbar and every key. G HUB software enables per-key actuation tuning from 0.1 to 4.0 mm, Rapid Trigger, multi-point actions and key priority settings. The keyboard works with PC and Mac systems.

Upgrade for analog precision seekers

This board replaces standard mechanical keyboards that lack adjustable actuation and rapid re-actuation. The jump is worth it for competitive players who need per-key sensitivity control and dual-function keystrokes. Buyers who want more than 39 analog keys or a wireless connection will not find those features here. The hot-swappable design suits enthusiasts who like to experiment with switch types.

Questions about this item

What does the 8K polling rate mean for real-world latency?

The 8K polling rate reduces the report interval to 0.125 ms, so keystrokes reach the PC eight times faster than a standard 1K rate.

What space does the 75% layout save on a desk?

The compact 75 percent form factor keeps the function row and arrow cluster while removing the numeric keypad for a smaller footprint.

How do I swap the included GATERON K20 analog switches?

Use the supplied keycap and switch pullers to remove keycaps, pull out the magnetic switches, and press the new ones into the 39 TMR beds.
