Fantech Atom Pro83 MK913 75% Tri-Mode Mechanical Gaming Keyboard – Red Switch, Saturn

Description

The Fantech Atom Pro83 MK913 is a compact 75% mechanical gaming keyboard combining wireless freedom, wired performance, customizable mechanical switches, and RGB lighting.

Its 83-key layout retains dedicated arrow and navigation keys while requiring less desk space than a full-size keyboard. Three connection modes—2.4GHz wireless, Bluetooth 5.0, and wired USB-C—allow it to work across gaming PCs, laptops, tablets, and other compatible devices.

This Saturn edition comes equipped with smooth linear Red mechanical switches, full-key NKRO anti-ghosting, 5-pin hot-swappable switch sockets, 22 RGB lighting modes, side-panel lighting, a programmable control knob, adjustable feet, and a rechargeable 2,000mAh battery.

Compact 75% Layout

The Atom Pro83 uses a space-saving 75% layout that retains frequently used functions without occupying the space required by a full-size keyboard.

It includes:

• Main alphanumeric section
• Function-key row
• Dedicated arrow keys
• Navigation keys
• Delete, Page Up and Page Down functions
• Programmable rotary control knob

The keyboard does not include a dedicated numeric keypad. Some secondary functions are accessed through the FN layer.

This format is suitable for gamers who want additional mouse space while retaining more dedicated keys than a 60% or 65% keyboard.

Tri-Mode Connectivity

2.4GHz Wireless

The included USB receiver provides a responsive wireless connection suitable for gaming and everyday computer use.

Use FN + Q to select 2.4GHz mode. If pairing is required, holding the combination for approximately five seconds activates receiver-pairing mode.

For the most stable gaming connection, connect the receiver directly to the computer or position it away from crowded USB 3.0 devices and other strong 2.4GHz wireless signals.

Bluetooth 5.0

The Atom Pro83 can save connections for as many as three Bluetooth devices.

Bluetooth channels are selected using:

• FN + E – Bluetooth device 1
• FN + R – Bluetooth device 2
• FN + T – Bluetooth device 3

This makes it possible to move between a laptop, tablet, and another compatible device without repeatedly pairing the keyboard.

Bluetooth is convenient for productivity and portable devices. The 2.4GHz connection is generally preferable for latency-sensitive gaming.

Wired USB-C

The detachable USB-C cable provides a stable wired connection while charging the internal battery.

Holding FN + Y selects wired mode.

Wired mode is recommended for:

• Competitive gaming
• Battery-free operation
• Keyboard software
• Macro configuration
• RGB customization
• Firmware updates

Connection procedures are documented in the MK913 user manual.

Mechanical Red Switches

The Saturn Red Switch version uses linear mechanical switches designed to travel smoothly without a tactile bump or loud click mechanism.

Red switches are particularly suitable for:

• Fast repeated key presses
• FPS games
• Action games
• Quiet shared environments
• Users who prefer smooth key travel
• General typing and productivity

The actual sound level also depends on keycaps, stabilizers, desk surface, typing force, and the keyboard’s internal construction. Mechanical Red switches are typically quieter than Blue clicky switches but are not silent.

5-Pin Hot-Swappable Sockets

Hot-swappable sockets allow the installed mechanical switches to be removed and replaced without soldering.

They support suitable MX-style mechanical switches, including many:

• 5-pin switches
• 3-pin plate-mount switches
• Linear switches
• Tactile switches
• Clicky switches

Optical, low-profile, Hall-effect, and other electrically incompatible switches will not work simply because they have a similar appearance.

For safe replacement:

1. Disconnect the USB cable.
2. Switch off wireless operation.
3. Remove the keycap using the included puller.
4. Remove the switch vertically with the switch puller.
5. Check that the replacement switch pins are straight.
6. Align the pins and press the switch gently into the socket.
7. Reinstall the keycap and test the key.

Avoid forcing a switch into the socket because bent pins or damaged hot-swap contacts may cause the key to stop registering.

Full-Key NKRO Anti-Ghosting

Full-key NKRO allows the keyboard to register multiple simultaneous key presses accurately.

This is useful for:

• Complex gaming commands
• Movement and ability combinations
• Rhythm games
• Fast typing
• Multi-key shortcuts

NKRO behavior can vary with the connected platform, Bluetooth implementation, and operating mode. Wired and 2.4GHz modes are recommended when maximum key-rollover performance is important.

RGB Lighting

The Atom Pro83 offers 22 lighting modes with adjustable brightness and animation speed.

Lighting controls include:

• FN + Up Arrow – Increase brightness
• FN + Down Arrow – Decrease brightness
• FN + Left Arrow – Reduce effect speed
• FN + Right Arrow – Increase effect speed
• FN + Insert – Change spectrum effect
• FN + Delete – Backlight test mode

Additional side-panel RGB lighting gives the keyboard a wider ambient lighting effect across the desk.

Wireless battery life varies considerably with lighting brightness, effect speed, connection mode, and usage. Lowering or disabling RGB extends operating time.

Multifunction Control Knob

The integrated rotary knob provides convenient control without using additional keyboard shortcuts.

Through the Windows software, its function can be configured for compatible actions such as:

• System volume
• Lighting adjustment
• Side-lighting control
• Mute
• Play and pause

Available options can depend on the installed software and firmware version.

Silicone Sound Dampening

An internal silicone sound-absorbing layer helps reduce hollow case resonance and soften typing acoustics.

It does not make the keyboard silent, but it can provide a more controlled sound compared with a completely hollow plastic case.

Windows and Mac Modes

The keyboard supports Windows and macOS key-function modes, with the manual listing FN + Alt as the system-mode toggle.

Basic keyboard operation is available on compatible macOS devices, but the dedicated configuration software is designed for Windows.

Key legends and certain shortcuts may not exactly match every macOS, tablet, or mobile-device function.

Configuration Software

Fantech provides Windows software for the Atom Pro83 MK913.

Available functions include:

• Key reassignment
• Macro recording
• FN-layer customization
• RGB effect customization
• Brightness and animation settings
• Knob-function customization
• Profile management

The configuration software works in wired mode and is not officially available for macOS. Software, manual, and firmware resources are listed on Fantech’s keyboard download page.

Basic keyboard operation does not require software.

2,000mAh Rechargeable Battery

The built-in 2,000mAh battery supports wireless operation over Bluetooth or the included 2.4GHz receiver.

Actual battery runtime depends on:

• RGB brightness
• Side lighting
• Lighting effect
• Bluetooth or 2.4GHz operation
• Typing frequency
• Sleep settings
• Battery condition

The keyboard can be charged and used through its USB-C connection. A USB wall charger is not required when it is connected to a powered computer port.

Specifications

Core specifications are confirmed on the official Fantech Atom Pro83 product page.

Some regional MK913 documentation lists the keyboard body closer to 330 × 134 × 42mm. Physical dimensions can therefore vary by revision or by measurement method and should be checked if exact sizing is required.

Compatibility

• Xbox games and applications
• Nintendo Switch setups using a compatible USB connection

Console support is determined by the console and individual game. Connecting the keyboard does not add keyboard controls to games that do not support them.
