WHAT EACH CHOICE ASKS OF YOU

What it brings and what to check

ASUS ROG Falchion Ace

What it brings

  • A 305.79 mm-wide 65% layout that keeps arrow and navigation keys, weighing about 599 g without the cable.
    Manufacturer source
  • Two USB-C ports allow flexible cable placement and quick switching between two PCs; six hot-key-selectable profiles and on-the-fly macro recording.
    Manufacturer source

What to check

  • There is no function row or number pad; F-keys and media controls sit on the Fn layer.
    Manufacturer source
  • It is wired only at 1000 Hz, ASUS lists only Windows 10 and 11, and the US eShop gives a one-year warranty.
    Manufacturer source

Logitech G512 X 75

What it brings

  • Logitech lists 81 swappable mechanical switch beds and 39 Dual Swap beds that accept its magnetic analog switches (0.1–4.0 mm actuation) or standard 3/5-pin mechanical switches.
    Manufacturer source
  • It adds two programmable knobs, a GAME MODE button and an 8 kHz report-rate option in a 75% footprint 330.2 mm across.
    Manufacturer source

What to check

  • Only nine analog switches are included, so adjustable actuation applies to those keys unless more are fitted; the rest use the pre-installed tactile switches.
    Manufacturer source
  • It is wired only, the palm rest is sold separately, and Logitech lists no rollover figure.
