ASRock B550 Phantom Gaming 4 AM4 ATX Motherboard DDR4
The ASRock B550 Phantom Gaming 4 is an AM4 ATX motherboard for Ryzen 3000 through 5000 series processors, built for gamers and overclockers who want solid power delivery, PCIe 4.0 storage support, and integrated audio tuning. It balances gaming-focused features with stability for both stock and overclocked systems.
Why this product
PCIe 4.0 for next-gen storage
One Hyper M.2 slot runs at full PCIe Gen4x4 speed, enabling modern NVMe drives to reach their rated performance without bandwidth compromise.
8-phase power delivery for overclocking
Premium 50A power chokes rated three times better than traditional designs deliver stable Vcore voltage and lower temperatures under load.
Nahimic audio with sound tracking
7.1 HD audio codec paired with directional sound positioning on a 360° radar helps you pinpoint in-game audio cues.
Dual GPU support via CrossFireX
Two PCIe x16 slots allow AMD graphics cards to work in tandem for higher frame rates in supported titles.
Addressable RGB headers for lighting sync
Onboard RGB and addressable RGB headers connect strips, fans and coolers; Polychrome RGB Sync matches effects across certified accessories.
