The ASUS TUF GAMING B450M-PRO II Motherboard supports AMD AM4 Socket for AMD Ryzen 5000 Series/ 5000 G-Series/ 4000 G-Series/ 3rd/2nd/1st Gen AMD Ryzen/ 2nd and 1st Gen AMD Ryzen with Radeon Vega Graphics/ Athlon with Radeon Vega Graphics Processors. It comes with Aura Sync RGB LED lighting, DDR4 4400MHz support, Dual M.2, and native USB 3.1 Gen 2. This motherboard features an unprecedented 108dB signal-to-noise ratio for the stereo line-out and a 103dB SNR for the line-in, providing pristine audio quality. It offers exclusive DTS Custom audio that delivers positional cues to stereo headphones, helping you to pinpoint enemies and action. ASUS TUF GAMING B450M-PRO II Motherboard comes with Fan Xpert 2+ that ensures every fan achieves the best balance of cooling performance and acoustics. Military-grade TUF chokes deliver rock-steady power to the CPU, helping to improve system stability. Its TUF Capacitors offer+20% temperature tolerance and 5X-longer lifespan. Lastly, TUF MOSFETS are military-grade MOSFETs with lower RDS(on). SafeSlot is the PCIe slot reinvented by ASUS and engineered to provide superior retention and shearing resistance. Manufactured in a single step using a new insert-molding process, SafeSlot integrates fortifying metal for an inherently stronger slot, which is then firmly anchored to the PCB through additional solder points. With x4 PCI Express 3.0 bandwidth, M.2 supports up to 32Gbps data-transfer speeds. A well-tuned system deserves a matching aesthetic. ASUS Aura offers full RGB lighting control with a variety of functional presets for the built-in RGB LEDs as well as strips connected to the onboard RGB headers. The ASUS TUF GAMING B450M-PRO II Motherboard comes with 3 years warranty.
