Overview
The Logicool G G512r-LN is a wired full-size mechanical keyboard built around GX Linear switches (the Cherry MX Red equivalent). The short version: if you want one mechanical keyboard under the mid-range price bar that won't drown your voice chat in clatter, this still earns a recommendation.
If you want hot-swap sockets, wireless, or a compact layout, look elsewhere.
On Amazon.co.jp, as of the June 3, 2026 capture, it holds 4.4 out of 5 stars across 1,422 reviews — an 88% positive score.
Few peripherals hold 4.4 at that review volume, which suggests low unit-to-unit variance rather than a handful of enthusiastic buyers.
The headline specs: 70 million keystroke rating, 445 × 132 × 36 mm, 1,130 g, roughly 16.8 million-color LIGHTSYNC RGB, and one USB 2.0 passthrough port.
Those numbers describe a keyboard tuned for stability and longevity, not portability.
Understanding the GX Linear switch
GX Linear is Logitech's own linear switch. Linear switches travel smoothly to the bottom with no tactile bump or click, which is why they suit rapid repeats and quick direction changes in FPS and MMO play.
The trade-off is real. Because nothing tells your finger the input registered, typists coming from tactile or clicky switches often bottom out hard at first and find typos harder to catch.
Most people adapt, but if you loved the click of a blue switch, this will feel hollow. Note too that "quiet" here means quiet for a mechanical keyboard — it is not a dampened silent switch, and bottom-out noise remains.
The 70-million-keystroke rating sits above the roughly 50 million typical of mainstream mechanical switches. In practice, keycap wear, cable fatigue, or plain boredom will end the keyboard's life long before the switches do.
Compatibility Guide
Connection is wired USB 2.0 with a fixed, non-detachable cable.
You need one free USB port to use the keyboard, and no driver install is strictly required. But if you want the passthrough port, the keyboard presents two USB plugs, so your PC needs two free ports.
On a laptop or mini PC with a tight port budget, check this before you buy.
The manufacturer lists Windows 10 / 8.1 / 8 / 7.
The product name mentions mac and Chrome, which is best read as "basic input works as a standard USB HID keyboard." Full Logitech G HUB customization — key remapping, per-key lighting — should be assumed to be a Windows-first experience.
This is a Japanese (JIS) layout model, so your OS keyboard layout must be set to Japanese; ANSI users should skip it.
Physically, 445 × 132 × 36 mm is a full-size footprint with a number pad, and 445 mm will not fit every sliding keyboard tray. The 1,130 g weight comes from the aircraft-grade aluminum-magnesium top plate: excellent for staying put during frantic play, poor for anyone who carries a keyboard around.
No palm rest is included, so budget for one if wrist angle matters to you.
Product Info
The price on Amazon.co.jp was ¥13,600 as of the August 27, 2026 capture, and the same ¥13,600 was recorded on June 3, 2026.
Two captures months apart at the same figure suggest a stable street price, but sales and point campaigns move it — always check the product page for the current number.
| Item | Value |
|---|---|
| Switch type | GX Linear (Red-equivalent) |
| Key life | 70 million actuations |
| Dimensions | 445 × 132 × 36 mm |
| Weight | 1,130 g |
| Connection | USB 2.0 (wired) |
| Backlight | RGB (approx. 16.8M colors) |
| USB passthrough | USB 2.0 × 1 |
Weight and thickness are the telling figures. At 1,130 g and 36 mm, this is deliberately not a slim wireless board.
With no battery, there is nothing to charge and one less latency variable — a straightforward "set it down and use it for years" tool.
The 16.8 million colors figure is simply 24-bit color, meaning no practical limit on hue choice.
LIGHTSYNC game-reactive lighting requires G HUB; without it, onboard presets still work.
Competitive Comparison
The same price bracket is crowded with hot-swappable enthusiast boards. The G512r-LN's advantages are the rigid metal top plate, domestic-warranty support, and a proven 1,422-review, 4.4-star track record.
Its disadvantages are equally clear: no hot-swap, wired only, non-detachable cable, and limited keycap-swap freedom.
If your idea of fun is swapping switches or chasing a gasket-mount sound profile, this is the wrong keyboard entirely — buy a hot-swappable model from the start. The G512r-LN is for people who buy once and never open the case.
Real-World Feel
The 1,130 g mass is what you notice first in use. Even with low-sensitivity FPS settings and wide mouse sweeps, the keyboard simply does not slide.
Rubber feet plus weight give it a planted feel.
On noise: there is no click, but bottom-out and stabilizer rattle remain. If your goal is late-night typing that nobody else in the house hears, a dedicated silent switch or added O-rings is the surer path.
Whether your microphone picks up the keys depends heavily on mic pattern and distance, so don't expect the keyboard alone to solve it.
Media control is FN-based; there is no dedicated volume roller. If you adjust volume constantly, that is a genuine compromise.
The game mode key disabling the Windows key is a practical touch.
Best Use Cases
- Voice-chat gamers — the linear switches keep key noise off your teammates' ears.
- People who never mod keyboards — 70M keystrokes and a metal plate suit buy-once ownership.
- Desktop users who need a number pad — full-size convenience, if you have 445 mm to spare.
- JIS layout users — a domestic-market Japanese layout with unambiguous legends.
- Anyone tidying dongle clutter — the passthrough port takes a wireless mouse receiver.
Before You Buy
It may consume two USB ports. One is enough without passthrough; using passthrough requires two.
Routing through a hub undercuts the point of the feature.
The passthrough is USB 2.0. Fine for receivers and thumb drives, not enough bandwidth for an external SSD.
Expecting fast transfers here is a common misread.
The cable is non-detachable — the single biggest long-term risk. If the strain relief fails, the keyboard is done.
Don't crush it under a chair caster or bend it sharply behind the desk.
Measure first. Confirm 445 × 132 mm fits your desk and that you accept carrying 1,130 g. Sliding keyboard trays are often too narrow.
Read the OS support carefully. The listing name mentions mac and Chrome, but official compatibility is stated for Windows 10 / 8.1 / 8 / 7.
Mac-first buyers who want full G HUB features should verify current support on the manufacturer's product page.
Finally, about the Amazon listing metadata: this product's retailer labeling shows inconsistencies (for example, an overseas store name attached to a domestic-market ASIN), so the displayed seller or price may not match reality. This happens with automatically collected data generally.
Before ordering, confirm the product image, the G512r-LN model number, and the domestic-genuine-product notation yourself — parallel imports can differ in layout and warranty handling.
FAQ
Q. Is GX Linear a silent switch? A.
No. It has no click, so it is quiet for a mechanical, but it lacks dampening and bottom-out noise remains.
Q. Can I swap switches or keycaps? A.
Hot-swap is not listed, so don't buy it planning to change switches. Choose a hot-swappable board for that.
Q. What should I plug into the passthrough? A.
Wireless mouse or headset receivers, or a thumb drive. Not high-speed external storage — it's USB 2.0.
Q. Does it work on Mac? A.
Basic input works as a USB keyboard, but the stated OS support is Windows-centric. Assume full G HUB features need Windows.
Q. What does it cost? A.
¥13,600 on Amazon.co.jp as of the August 27, 2026 capture.
Prices move with sales — check the listing for the current figure.
Q. Does the FF XIV recommended-model badge add anything? A.
It indicates suitability, not extra hardware. Judge it on its specs as a linear-switch G512.
