FAQ
What devices is this power cable compatible with?
The Supermicro CBL-PWEX-0786 is specifically designed for Graphics Processing Units (GPUs) and server applications. It has been validated for compatibility with NVIDIA Tesla GPU accelerators including K40 and M10 models, as well as Supermicro SuperServer platforms such as the 1028GQ-TR and 1028GQ-TRT systems. The cable provides power connectivity for components requiring PCI-E power interfaces in these computing environments.
What are the connector types on this power cable?
This power cable features an 8-pin connector on one end and a 6+2pin PCI-E connector on the opposite end. The 6+2pin configuration provides flexibility for different GPU power requirements, allowing the cable to adapt to either 6-pin or 8-pin PCI-E power inputs as needed. Both connectors are designed for secure attachment and reliable power transmission in server and GPU installations.
What is the voltage rating of this power cable?
The Supermicro CBL-PWEX-0786 is rated for 12 V DC power delivery. This voltage specification matches the standard power requirements for PCI-E devices and GPU accelerators, ensuring compatible power transmission for supported computing components. The cable is engineered to maintain stable 12 V DC power flow between connected devices in server and GPU installation scenarios.
How long is this power cable?
This power cable measures 4.3 inches in length, making it an ultra-short cable designed specifically for installations where space optimization is critical. The compact length minimizes excess cable within server chassis and GPU installations, reducing cable clutter that can impede airflow and complicate maintenance access in high-density computing environments.
Why would I need an ultra-short power cable?
Ultra-short power cables like the 4.3-inch CBL-PWEX-0786 are essential in high-density server racks and GPU installations where internal space is limited. The compact length reduces cable clutter that can obstruct airflow and increase operating temperatures, while also simplifying cable management and improving accessibility for maintenance and upgrades. This design is particularly valuable in computational clusters and data center environments where thermal management and space utilization directly impact system performance and reliability.
Is this cable compatible with standard desktop PCs?
While the CBL-PWEX-0786 uses standard PCI-E power connectors, it is specifically engineered and validated for enterprise server and GPU accelerator applications, particularly Supermicro server platforms and NVIDIA Tesla GPU accelerators. The ultra-short 4.3-inch length is optimized for server chassis installations rather than standard desktop PC cases. For desktop applications, longer standard power cables would typically provide more flexible installation options and better compatibility with standard PC case layouts.
