12VHPWR adapter (12VHPWR output on the left, four 8-pin inputs on the right) supplied with Nvidia RTX 4090 cards. The 16-pin 12VHPWR connector is a standard for connecting graphics processing units (GPUs) to computer power supplies for up to 600 W power delivery. It was introduced in 2022 to supersede the previous 6- and 8-pin power connectors ...
12-pin for PCI Express graphics cards, each PCI Express 12-pin connector can output a maximum of 648 W (12V, 9A), 2 150 W 8-pin can be combined via an adapter cable to form one 648 W 12-pin. 16-pin 12VHPWR connector for PCI Express graphics cards, each PCI Express 16-pin connector can output a maximum of 662 W (12V, 9.2A), 12 power pins, 4 ...
OCuLink (standing for "optical-copper link", since Cu is the chemical symbol for copper) is an extension for the "cable version of PCI Express". Version 1.0 of OCuLink, released in Oct 2015, supports up to 4 PCIe 3.0 lanes (3.9 GB/s) over copper cabling; a fiber optic version may appear in the future.
Many 64-bit PCI-X cards are designed to work in 32-bit mode if inserted in shorter 32-bit connectors, with some loss of performance. [22] [23] An example of this is the Adaptec 29160 64-bit SCSI interface card. [24] However, some 64-bit PCI-X cards do not work in standard 32-bit PCI slots. [25] [unreliable source?]
Mobile PCI Express Module (MXM) is an interconnect standard for GPUs (MXM Graphics Modules) in laptops using PCI Express created by MXM-SIG. The goal was to create a non-proprietary, industry standard socket, so one could easily upgrade the graphics processor in a laptop, without having to buy a whole new system or relying on proprietary vendor ...
The device is programmed with an address to write to (this address is generally a control register in an interrupt controller), and a 16-bit data word to identify it. The interrupt number is added to the data word to identify the interrupt. [1] Some platforms such as Windows do not use all 32 interrupts but only use up to 16 interrupts. [7]
SXM (Server PCI Express Module) [1] is a high bandwidth socket solution for connecting Nvidia Compute Accelerators to a system. Each generation of Nvidia Tesla since P100 models, the DGX computer series and the HGX boards come with an SXM socket type that realizes high bandwidth, power delivery and more for the matching GPU daughter cards.

PCI-X is specified for both 32-and 64-bit PCI connectors, [3]: 14 and PCI-X 2.0 added a 16-bit variant for embedded applications. [ 2 ] : 22 PCI-X has been replaced in modern designs by the similar-sounding PCI Express (PCIe), [ 4 ] with a different physical connector and a different electrical design, having one or more serial lanes instead of ...
