ASUS’s Cableless GPU Power Connector Delivers Up To 600W But Proprietary In Nature
ASUS has further detailed its cableless GPU power connectors for gaming GPUs that can deliver up to 600W of power, replacing the 12VHPWR design.
ASUS has released detailed documents of its new cableless power connector, which reveals the working mechanism and some interesting facts. For those who are unaware, back at Computex 2023, we got our first look at the GC-HPWR connector featured on an ASUS RTX 40 GPU & a Z790 motherboard in exclusive coverage.
More recently, at the Bilibili World event, ASUS once again showed its new graphics cards with a more finalized design and confirmed that they will be going into mass production later this year. However, the documentation published reveals that the new connector holds immense potential, capable of even delivering the GeForce RTX 4090 adequate power output.
The GC-HPWR connector features four different groups of pins, responsible for power delivery and communication between the motherboard and the GPU. It will be positioned right beside the PCIe x16 slot, allowing an easier installation process, which is supported by the PCIe slot itself. It is said that the new connectors have their origin in the server industry, & it is modified in a way to support the power delivery required by current-gen GPUs.
Detailing on "power delivery", ASUS's documentation reveals that the connector is capable of delivering up to 600W of power, which is the maximum rated power that the 12VHPWR also offers. We have seen the connector's integration in ASUS's Megladoon GeForce RTX 4070, which is limited to 200W, hence ASUS is playing the safe side here. However, we could expect a potential debut in higher-end "Ada Lovelace" GPUs as well given that the connector is successful in the mainstream markets.
