ASRock B550 Phantom Gaming 4 ATX Gaming Motherboard

The ASRock B550 Phantom Gaming 4 delivers robust performance for AMD Ryzen processors with gaming-focused features and reliable power delivery. Built on the AMD B550 chipset with AM4 socket compatibility, this ATX motherboard supports 3rd Gen AMD Ryzen processors and future AMD Ryzen CPUs, providing a solid foundation for gaming and productivity builds.

Power Delivery and Overclocking

Equipped with an 8-phase power design and Digi Power technology, this motherboard ensures stable power delivery to your CPU. Premium 50A power chokes provide up to three times better saturation current compared to traditional chokes, delivering enhanced Vcore voltage stability. The 2oz copper PCB construction offers lower temperatures and higher energy efficiency, essential for overclocking DDR4 memory up to 4733+ MHz.

Expansion and Storage

The B550 Phantom Gaming 4 features dual M.2 slots, including a Hyper M.2 socket supporting PCIe Gen4 x4 for maximum NVMe SSD performance, and a secondary M.2 socket capable of PCIe Gen3 x2 and SATA3 modes. Six SATA III ports provide ample storage connectivity. The reinforced PCIe 4.0 x16 steel slot ensures signal stability and secure installation for heavy graphics cards, while AMD CrossFireX support enables multi-GPU configurations.

Connectivity and Audio

Gigabit LAN ensures reliable network connectivity, while eight USB 3.2 Gen1 ports (six rear, two front) offer fast data transfer speeds. The Realtek ALC1200 audio codec with Nahimic Audio technology delivers immersive 7.1 channel HD audio with Sound Tracker for 360-degree positional audio during gaming sessions.

Build Quality and Features

The sapphire black PCB with high-density glass fabric construction protects against electrical shorts from humidity. XXL aluminum alloy heatsinks effectively dissipate heat from MOSFETs and the chipset for stable system performance. The Post Status Checker LED provides quick troubleshooting by indicating CPU, DRAM, VGA, and boot status at startup. Full Spike Protection safeguards sensitive components from unexpected voltage surges.

RGB Customization

Onboard RGB headers and an addressable RGB header allow connection to compatible LED devices including strips, fans, and coolers. Polychrome RGB Sync certification enables synchronized lighting effects across compatible accessories for personalized system aesthetics.
