Talk:Expansion card
From Wikipedia, the free encyclopedia
how are expanison cards supplied with power - is this dependent on the bus architectur (do buses contain a "power line") —The preceding unsigned comment was added by 83.64.80.66 (talk • contribs) 18:00, September 1, 2005 (UTC)
- They must do, and presumably two or more pins are reserved for this purpose - I cannot find any information on this subject. Several PCI-E graphics cards on the market now have a molex connector as well because they use so much power.--ChrisJMoor 13:46, 26 January 2007 (UTC)
- I stand corrected, the pin assignment of almost every backplane computer bus is available here (in the external links section of this article!). It is...mostly clear which pins are power supply/ground. Perhaps it should be mentioned that the physical bus connectors usually have power pins.--ChrisJMoor 14:04, 26 January 2007 (UTC)
