Comprehensive Fan Controls
TUF GAMING B660M series motherboards feature comprehensive fan controls that can be configured via the Fan Xpert 2+ utility or the award-winning ASUS UEFI BIOS.

DRAM Overclocking Performance
DDR4 OC 5333
Improvements to trace routing design provide the latest Intel processors with enhanced access to memory bandwidth. ASUS OptiMem II technology carefully maps memory signal pathways across different PCB layers to reduce path distance, and it adds shielding zones that significantly reduce crosstalk.

Two PCIe 4.0 M.2
The Two PCIe 4.0 M.2 slots support up to two 2280 devices and also provide NVMe SSD RAID support for incredible performance potential. Create a RAID configuration with up to two PCIe 4.0 storage devices to enjoy the fastest data transfer speeds.

CONNECTIVITY
PCIe 5.0
The 12th Gen Intel processors bring PCIe 5.0 support to the market. PCIe 5.0 offers twice the data transfer speed of PCIe 4.0, making it robust enough to handle new data-heavy tasks. PCIe 5.0 also brings other benefits, such as electrical changes to improve signal integrity, backward-compatible CEM connectors for add-in cards, and backward compatibility with previous versions of PCI Express

Front USB Port
A full complement of USB ports support high-end rigs loaded with peripherals, including a front-panel USB 3.2 Gen 1 Type-C® connector that provides data transfer speeds of up to 5 Gbps.

USB 3.2 Gen 2x2 Type-C®
Extensive USB support ensures connections to a wide array of peripherals. TUF GAMING B660M-PLUS D4 includes a USB 3.2 Gen 2x2 Type-C® port on the rear I/O panel that delivers increased bandwidth and transmission speeds of up to 20 Gbps.

Thunderbolt™ 4 Support
TUF GAMING B660M series features Thunderbolt™ 4 support via an on-board header. With an Intel-certified ASUS ThunderboltEX 4 add-on card* TUF GAMING B660M-PLUS D4 can also enable bi-directional speeds of up to 40 Gbps on a single cable. Additionally, this card has a daisy-chain function for multi-screen connection and supports up to an 8K resolution display. It can also provide up to 100 watts of power to fast-charge devices.
* ASUS ThunderboltEX 4 add-on card is sold separately.

Easy PC DIY
TUF GAMING motherboards are designed to be easy to set up and configure just the way you want — even for first-time builders. The TUF GAMING Alliance ecosystem makes selecting compatible parts easy, while Armoury Crate software provides Fan Xpert 2+ and hardware information and offers full full control of Two-Way AI Noise Cancellation, RGB lighting and peripheral settings. The TUF GAMING platform gives you the arsenal you need to build and optimize your dream gaming rig, without unnecessary complexity.

Build with Confidence
TUF GAMING Alliance is a collaboration between ASUS and trusted PC component brands to ensure compatibility across a wide range of parts, such as PC cases, power supplies, CPU coolers, memory kits and more. With new partnerships and components being added regularly, the TUF Gaming Alliance will continue to grow even stronger. Learn More

TUF PROTECTION
SafeSlot & SafeDIMM
PCIe 5.0 is 2x faster than PCIe 4.0, so we adapted our SMT manufacturing process for the faster SafeSlot, to ensure the highest data speeds. SafeSlot is a reinforced metal sheath added to a PCIe slot to keep a card firmly installed. Meanwhile, strong ASUS SafeDIMM sheathes support and protect memory modules on select ASUS motherboards, empowering you to insert your modules with speed, accuracy and confidence.

ESD Guards
ESD Guards prolong the life of components while preventing damage from electrostatic discharge, providing protection for up to +/- 10 kV of air discharge and +/- 6 kV of contact discharge — greatly surpassing the respective industry standards of +/- 6 kV and +/- 4 kV. Surface-mounted TVS diodes in a dual in-line package help protect your PC from voltage spikes.

TUF LANGuard
TUF LANGuard is a military-grade innovation that integrates advanced signal-coupling technology and premium surface-mounted capacitors to improve throughput, protecting the motherboard from lightning strikes and static electricity.

DRAM Overvoltage Protection
Onboard resettable fuses prevent overcurrent and short-circuit damage. This extends beyond I/O ports to DRAM to safeguard the lifespan of your system and connected devices.

Stainless Steel Back I/O Panel
TUF GAMING motherboards have a corrosion-resistant stainless steel back I/O panel bonded with chromium oxide to provide a lifespan that’s three times longer than traditional panels. With this protective feature, TUF GAMING motherboards passed 72-hour salt fog testing, while other brands only passed 24-hour testing.

Immersive Gaming
TUF GAMING B660M series motherboards provide a high-performance gaming package with a long list of features to improve your experiences, including ultrafast networking for smoother online gameplay, pristine audio with positional cues for FPS gaming, and onboard RGB lighting that syncs with attached accessories to help you create a personalized gaming atmosphere.

Networking
EXCLUSIVE 2.5 GIGABIT ETHERNET
2.5G on-board Ethernet kicks your LAN connection up a notch with an up to 2.5X bandwidth improvement. Using your existing LAN cable, you can take advantage this networking upgrade to experience smoother, lag-free gaming, immediately stream high-resolution videos and enjoy faster file transfers.

Two-Way AI Noise Cancelation
This powerful ASUS-exclusive utility leverages a massive deep-learning database to reduce background noise from the microphone* and incoming audio while preserving voices. Distracting keyboard clatter, mouse clicks and other ambient noises are removed so you can hear and be heard with perfect clarity while gaming or during calls.

Realtek 7.1 Surround Sound
1. TUF Gaming audio chip protection
Enhanced electrical shielding preserves the integrity of audio signals to ensure the best quality.
2. High-definition audio
Premium audio capacitors provide warm, natural and immersive sound.
3. Audio shielding
Our specialized audio path design separates analog and digital signal domains to significantly reduce multi-lateral interference.

DTS Audio Processing
DTS Audio Processing enhances gaming headset and speaker audio experiences by reducing distortion and by providing deeper bass, so games, movies and music sound better. It also allows you to customize audio settings.

Outshine the Competition
A well-tuned system deserves a matching aesthetic. TUF Gaming B660M series features edge lighting to enhance its rugged look, and now the PCH heatsink gets RGB lighting to take the style even further. ASUS Aura offers full RGB control with a variety of functional presets for built-in LEDs as well as third-party strips you can connect to onboard RGB headers. And it can all be synced with an ever-growing portfolio of Aura-capable hardware.

Addressable Gen 2 RGB Header
The addressable Gen 2 RGB header is now capable of detecting the number of LEDs on second-gen addressable RGB devices, allowing the software to automatically tailor lighting effects to specific devices. The new header also offers backward-compatibility with existing addressable RGB gear.
