For the sake of the overall beauty of the host, many manufacturers have designed a back-plug motherboard with the power slot on the back. However, since the graphics card exists independently, it is difficult to hide the power cord, so ASUS designed a design called “” GC-HPCE / HPWR” power interface, through the motherboard to supply power to the graphics card to avoid external wires, and this interface can also supply more than 600W of power consumption. ASUS initially demonstrated a TUF Gaming graphics card with a GC-HPCE interface and a back-mounted motherboard at Computex 2023, allowing the entire host to achieve a “completely visually wireless” effect. The pin position design of the display card. The pin size specification on the display card. The connector design specification on the motherboard. The motherboard connector size specification. The signal and power definition of each pin on the graphics card. Look at 900W. The definition of the signal and power pins on the motherboard Recently, the well-known whistleblower @momomo_us posted a series of related specifications and design drawings on the GC-HPCE interface on X. From the photos, we can see that GC-HPCE is composed of 12+16 It consists of 12 pins, 12 of which are used for signal transmission, and the remaining 16 are used for power supply. In addition, on the screenshot of the explanation about the definition of the power signal of the graphics card, you can see that the minimum requirement of GC-HPCE is to allow the motherboard and graphics card to withstand a power consumption of 600W, and even a 900W version can be made if conditions permit! In fact, GC-HPCE itself is magically modified from the HPCE interface. HPCE is mainly used in the industrial field to provide server equipment with ultra-high power consumption, so theoretically, GC-HPCE will be safer in terms of security. It is more reliable than the 12VHPWR used on NVIDIA GeForce RTX 40 series. After all, the former has been used in related fields for quite a while before the transformation. However, the GC-HPCE interface is not without its shortcomings. The most intuitive point is the issue of versatility. Even though ASUS stated that GC-HPCE is an open license, any manufacturer can use it, but so far only ASUS has displayed related products. I don’t know if other manufacturers want to follow suit. At the same time, GC-HPCE is at best just changing the connection method of the wires, from the original power supply to the graphics card, to the power supply connected to the motherboard, and then the motherboard supplies power to the graphics card. It will not be reduced, but because there is an extra transfer process, once the GC-HPCE really has an accident, it will “take away” the motherboard and graphics card instead. However, judging from the outflow of design drawings this time, it is speculated that ASUS should plan to mass-produce or carry out experimental promotion. After all, many manufacturers are indeed trying wireless and back-plug computer assembly designs recently. No, maybe we will be able to see related products launched on the next generation of motherboards and graphics cards.
