The new graphics card power supply interface 12V-2×6 has excellent performance
Recently, Hardware Busters conducted rigorous tests on the 12V-2×6 connector as stipulated in the ATX 3.1 standards, aiming to discern the disparities between it and the 12VHPWR. The findings were revealing: under a load of 55A and after approximately 30 minutes of operation, the 12V-2×6 connector exhibited exemplary thermal performance. The surface temperatures of both the cable and the plug did not exceed 46.5℃, fully in compliance with safety standards. Additionally, the 12V-2×6 connector rectified the safety concerns caused by poor contacts within the 12VHPWR interface.
Hardware Busters subjected the 12V-2×6 connector to two distinct testing conditions: one with the plug fully engaged and another with only a partial insertion. In both scenarios, a robust 640W rated power was applied to ensure ample stress. Intriguingly, the 12V-2×6 showcased remarkable efficiency in power transmission through its pins. Remarkably, under the partially inserted state, the connector’s temperature witnessed a reduction, settling at a mere 41℃. Hardware Busters posits that the utilization of low-resistance pins by the 12V-2×6 connector is pivotal in curbing thermal generation. As such, even in cases of unsteady insertion, overheating becomes nearly implausible, effectively mitigating the overheating issues commonly associated with the current 12VHPWR connectors.
According to prior reports, NVIDIA has opted to equip numerous models within their GeForce RTX 40 series Founder Edition graphics cards with the 12V-2×6 connector, addressing the melting problems due to overheating with the 12VHPWR connector. FSP has also resolved to upgrade its entire 2023 product lineup, embracing the 12V-2×6 standard throughout.
