![]() ![]() Over 12 lines, this gives these cabled a maximum power capacity of 684 watts (9.5 x 12 x 6). With cables from Amphenol, their 12VHPWR power lines are designed to handle 12V at 9.5 amps. With 12 power lines and four signal lines, the 12VHPWR cable is designed to deliver over 650 watts of power, which is more than enough to meet the needs of any modern graphics card. This change will enable new GPUs to be powered by a single cable, reducing cable clutter and the design complexity of future graphics cards. The lacklustre power providing capacity of today's cables has resulted in graphics cards that feature three 8-pin PCIe power connectors, creating a lot of unnecessary cable clutter wasted PCB space on modern hardware.Ĭreating a higher capacity cable allows the industry to take a single cable approach to new high-end GPU/accelerator designs. In an era where modern high-end GPUs can consume over 400 watts of power, these cables are no longer enough to meet the requirements of modern PC hardware. Today's 8-pin PCIe power cables can provide users with up to 150 watts of power per cable. Igor's Lab has since looked into this rumoured cable design and found a new connector type called "12VHPWR". Nvidia's rumoured RTX 3090 Ti graphics card reportedly featured a new 16-pin PCIe power connector (via Videocardz) that could handle the power draws of modern graphics cards. ![]() Last week, we reported on a rumoured RTX 3090 Ti graphics card with a TDP of 450 watts, a graphics card that highlights why today's 150W 8-pin PCIe power connectors are no longer fit for purpose. Today, high-end graphics cards can feature up to three 8-pin PCIe power connectors, creating a cable management nightmare for PC builders and design challenges for GPU manufacturers, PSU makers, and case designers. What's worse is that GPUs are only set to become more power hungry, as both AMD and Nvidia are working on multi-die GPU architectures designed to deliver incredible performance levels and higher maximum power draws. Today's graphics cards can consume insane amounts of power.
