90A Power Phase and Quick-Release Armour

A 16+2+1 phase design rated at 90 amps per phase feeds the CPU cleanly under heavy loads. Full-coverage cooling armour with quick-release latches simplifies maintenance, while integrated ARGB lighting adds visual flair. The PhantomLink connector links the motherboard directly to a compatible graphics card backplate for synchronised control.

Dual USB4 40G and Wi-Fi 7 Connectivity

Two rear USB4 ports at 40 Gbps and a front-panel USB-C header at 20 Gbps provide high-speed peripheral bandwidth. Onboard Wi-Fi 7 and Bluetooth 5 handle wireless duties, and a 5G wired LAN port covers wired networking. Four M.2 slots support dual PCIe 5.0 SSDs, while onboard display and quick-control buttons aid troubleshooting and tuning.

Questions about this item

What USB4 speed does the rear I/O cap at?

Dual rear USB4 ports deliver 40 Gbps each, so the practical ceiling is 40 Gbps per port.

What clearance does the full-coverage cooling armor need?

The quick-release armor covers VRM, chipset and M.2 zones and includes a backplate; allow extra height for the ARGB lighting module.

How is the PhantomLink graphics-card backplate connector fitted, and what step is often missed?

Align the board-side PhantomLink header with the matching cut-out on the card backplate, press until the latch clicks, then connect the ARGB cable — skipping the ARGB link leaves lighting uncontrolled.
