FSP plans to update its entire 2023 product lineup, supports ATX 3.0 “12V-2×6” standard

In the latest generation of its GeForce RTX 40 series graphics cards, NVIDIA extensively employed the 12VHPWR interface. Owing to certain design flaws, there have been numerous reports of these 12VHPWR connectors overheating and melting. Although many attribute these incidents to “user installation errors,” a shared understanding has emerged that the bending of cables can exert undue pressure on contact points, thereby heightening the inherent risk.

Earlier reports suggested that PCI-SIG has been crafting a new connector design dubbed the “12V-2×6 PCIe 6.0,” set to feature in the CEM 5.1 specifications, replacing the existing PCIe 5.0 standard’s 12VHPWR. According to Wccftech, FSP has resolved to upgrade its entire 2023 product lineup, ensuring that these ATX 3.0 power supplies fully endorse the “12V-2×6 PCIe 6.0” standard.

The initial suite of products to undergo this transformation includes the Hydro G PRO series, the Hydro PTM series, and the Dagger PRO series. Subsequent updates will be extended to other products, spanning from gold to titanium-grade offerings, catering to the diverse power needs of various users. FSP elucidated that to achieve full compliance with the new standard, firmware updates for either the graphics cards or the power supplies are requisite.

In fact, NVIDIA has already outfitted numerous models of its GeForce RTX 40 series Founder Edition graphics cards with the “12V-2×6 PCIe 6.0” connector. It’s understood that in the original CEM 5.0 specifications, the inward offset of the tip was a mere 0.45mm. In the revamped version, this offset has been increased to 1.7mm. In comparison to the original design, the new connector has shortened its sensing pins (the four data pins defining wattage). If the 12VHPWR cable is not fully connected, the power supply will be restricted to prevent potential overheating and melting due to excessive power draw.
