RULE YOUR OWN LIGHTING WAY WITH POLYCHROME RGB
Steel Legend motherboards deliver stunning performance and superior aesthetics to rule your own colorful lighting way! ASRock offers highly comprehensive control to smoothly utilize the built-in RGB LEDs or connected LED strips, CPU fans, coolers, chassis and any other compatible RGB devices. Devices can be synchronized across the Polychrome RGB Sync-certified line of accessories as well.
A SOLID M.2-SOLUTION PERFORMER
Dual M.2 for SSDs That Supports Type 22110 M.2
The B450 houses two of the world’s fastest M.2 slots. One slot delivers up to PCIe Gen3 x4 32Gbps transfer speed, the other one supports PCIe Gen3 x2 & SATA3 6Gbps mode.
Good M.2 SSD protection is important for longevity and stability. ASRock has provided a complete M.2 armor solution on the B450 platform that makes SSDs run perfectly at low temperatures.
Dual USB 3.1 Gen2 (Type-A Type-C)
This motherboard has a pair of onboard Type-A and Type-C USB 3.1 Gen2 ports built on the rear I/O to support next-generation USB 3.1 Gen2 devices while delivering up to 10 Gbps data transfer rates.
ULTRA USB POWER – ULTRA STABLE POWER
The 5V voltage on these motherboards is transferred from the 12V, supplying enough current to USB devices without dropping voltage directly from the PSU.
Protect your mouse and keyboard against static electricity. This especially lowers the chances of USB mouse lag or stuttering.
PURE AUDIO QUALITY
The USB speaker is best connected via Ultra USB Power ports to execute a pure current while offering high audio quality without distortion.
2 oz Copper
This motherboard has been made with 2 ounces of copper inner layers. The copper materials for PCB layers were carefully selected to deliver lower temperatures and higher energy efficiency for overclocking.
PREMIUM 60A POWER CHOKE
ASRock’s premium 60A power chokes effectively make the saturation current up to three times better, thus providing enhanced and improved Vcore voltage to the motherboard.
PCI-E STEEL SLOT
The advanced PCI-E steel slot packed with a solid cover prevents any signal interference with graphics cards. It also ensures that heavy graphics cards can be safely installed in the PCI-E slot.
Full Spike Protection
Some sensitive digital components on the motherboard are vulnerable to power surges, the excessive current may cause your system to malfunction immediately. ASRock Full Spike Protection includes various technologies to prevent your motherboard’s components from being damaged by these unexpected voltage spikes.
Live Update & APP Shop
The ASRock Live Update & APP Shop is designed for your convenience. We provide various apps and support software for users to download. You can also easily optimize your system and keep your motherboard up to date with ASRock Live Update & APP Shop.
