A4Tech BLOODY B760 gaming keyboard — Full-size 100%, USB, Optical switches, RGB, Black

A4Tech BLOODY B760 is a wired full-size (100%) gaming keyboard with a USB interface, LK optical switches and RGB backlighting. The keyboard combines a standard layout with a metallic aluminum-alloy surface and reinforced space-bar construction to offer a balance of durability and fast input response. Designed for gaming and everyday typing, the B760 provides low-latency optical actuation and full key rollover to register simultaneous key presses reliably.

Advantages

The LK optical switch technology delivers a 0.2 ms key response and zero digital latency compared with conventional mechanical switches, improving reaction time for fast-paced games. Full N-key rollover ensures every keypress is detected even when multiple keys are held down, including modifier keys. The aluminum-alloy top and screw-enhanced space-bar structure increase structural durability, while RGB backlighting with adjustable brightness provides visual customization and visibility in low-light environments.

Suitable for

• First-person shooters (FPS) where fast key actuation matters
• Massively multiplayer online games (MMO) that require multiple simultaneous key presses
• General office and productivity tasks using a standard full-size layout
• Evening or dimly lit setups that benefit from RGB backlighting

How to use

Connect the keyboard to a computer using the USB cable; no additional drivers are required for basic operation on most operating systems. Use the standard layout and numeric keypad as you would on any full-size keyboard. Turn the RGB backlight on or off with the Fn + F12 key combination and adjust brightness with Fn + Up/Down. The LK optical switches provide immediate actuation, so avoid resting fingers heavily on keys during rapid input if you wish to prevent unintended presses.

Usage recommendations

For consistent performance, place the keyboard on a stable, flat surface and ensure the USB connection is secure. Use a wrist rest if extended typing or gaming sessions cause strain. Periodically clean the keycaps and top surface with a soft, dry cloth; avoid liquid cleaners on the electronic parts. The keyboard is optimized for low-latency gaming and multi-key combinations, making it suitable for competitive play and intensive productivity workflows.
