Flexible control options

Fan Xpert 2+ software provides comprehensive control over your system fans. Auto-Tuning mode intelligently configures all parameters with a single click. There is also an Extreme Quiet mode, which reduces the chassis fan speed below the default minimum to keep your system completely silent when performing light tasks. The fans can also be controlled via the UEFI BIOS.

Comprehensive motherboard cooling and protection

The Prime B550M-K motherboard is engineered with an array of hybrid fan headers and features comprehensive cooling controls that are configurable via Fan Xpert 2+ software or through the UEFI BIOS, ensuring your rig stays cool and stable under intense workloads. A VRM heatsink with thermal pads improves heat transfer from the MOSFETs and chokes for better cooling performance, while the Prime B550M-K series features comprehensive cooling controls that are configurable via Fan Xpert 2+ software or through the UEFI BIOS. Each header can dynamically reference three thermal sensors, which optimises cooling for GPU- and CPU-intensive tasks. In addition, Fan Xpert 2+ lets you map the temperature of supported ASUS graphics cards and adjust cooling to suit your current needs.

Even the little things can make a big difference

The Prime B550M-K series features fine details that enhance every experience, from exclusive codecs that provide pristine audio quality to intuitive RGB lighting controls that let you customise your system for a unique, personal look. Integrated onboard features for even better sound combine intelligent design and premium hardware to create audio quality unlike anything you've ever experienced. Separating the analogue/digital signal domains significantly reduces multi-lateral interference, a separate layer for the left and right tracks ensures minimal crosstalk between audio paths, and premium Japanese-made capacitors provide a deeply immersive sound signature with exceptional fidelity.

SafeSlot Core

SafeSlot Core is the ASUS-exclusive PCIe slot, featuring a special hook that anchors it more firmly to the motherboard, providing 1.6× stronger retention and 1.3× greater shearing resistance than standard slots, while ASUS Prime motherboards have reinforced solder points around both the PCIe and DIMM pins. The world-class circuit-protecting power design includes built-in voltage regulators to protect the board from overvoltage from lower-quality power supplies, and onboard resettable DRAM fuses provide protection against overcurrent and short-circuit damage, extending the life of your system and connected devices. The corrosion-resistant stainless-steel back I/O panels, bonded with chromium oxide, have a lifespan three times longer than ordinary panels, while ASUS LANGuard technology increases network throughput and provides 2.5× greater surge tolerance by combining advanced signal-coupling technology and premium anti-EMI capacitors to ensure a more reliable connection.

Choosing a motherboard

When choosing a motherboard (also known as a mainboard), it's important to pay close attention to the motherboard's socket type, form factor, and chipset. These are among the most crucial parameters and ensure the board's compatibility with the processor, expansion cards, and other components. The specific socket will determine the choice of a suitable processor, while the remaining connectors will dictate the selection of other components for your future computer.

dobrý den, musí bý upgrade biosu když bych osadil desku procesorem AMD RYZEN 3 3100? A bude vhodná grafika ASUS DUAL GTX 1660 SUPER EVO O6G?

Dobrý den, podporuje tato deska grafickou kartu NVIDIA GeForce GT 440 (MSI) Děkuji

Dobrý den, chtel bych se zeptat jestli tato deska dorazí s nainstalovaným BIOSEM, který podporuje procesor amd ryzen 5 5000

Podporuje deska grafickou kartu GTX 960 4gb? A je kompatibilní s windows 11? Predem díky za odpověď

Dobrý den, podporuje ryzen 5500 bez aktualizace BIOS?

Dobrý den chtěl bych se zeptat jestli mohu tuto základní desku použít jako herní děkuji za odpověď

Dobrý den mám tuto základní desku osazenou procesorem ryzen 7 5700g. Chtěl bych upgrade ram z 2x8gb na 2x16gb. Jaké byste doporučili. Děkuji za odpověď Petr

zdravím zvládne tato deska s ryzen7 5700G dva monitory tu integrovanou grafickou ? na přiklad jen pres DVI a druhy HDMI nebo VGA

Dobrý den, bude fungovat v této desce procesor první řady Ryzen 3 1200 AF? Na stránkách ASUSu uvádějí pouze podporu CPU Ryzen od třetí řady. Mám tu několik těchto procesorů a chci postavit pár kancelářských PC, které v budoucnu ještě můžu upgradovat.

podporuje tato doska 5700x ? Ak nie, má flashback port na nainštalovanie noveho biosu ?
