- SPS (Smart Power Stage) - The server grade ultra low loss PCB improves signal integrity, allowing motherboard to support PCIe 5.0 for both graphics card and M.2 SSD, it also improves memory OC potential to deliver the most extreme memory performance.
- 20+2 Power Phase Design - The 14 Layer PCB provides stable signal traces and power shapes delivering lower temperature and higher energy efficiency, ensures a reliable and long-lasting system while delivering ultimate performance without any compromise.
Compares to conventional DIP style PCIe slot, the SMT type PCIe slot improves signal flow and maximize stability under high speed, a key breakthrough to fully support the lighting speed of the latest PCIe 5.0 standard.
The reinforced steel slot is capable of supporting PCI Express 5.0 standard. The various benefits include:
- Extra anchor points
- Stronger latch
- Ensure signal stability
- Make sure heavy graphics cards to be well-installed.
Thunderbolt Technology
- Thunderbolt™ 4/USB4 Type-C - Thunderbolt™ 4/USB4 technology brings speed and versatility to the most advanced USB Type-C, offering a fast and simple level of connection for work or home. It enables lightning-fast data transfer up to 40Gbps and connects external monitors, Thunderbolt™, and USB devices with a single Thunderbolt 4 cable.
