molex power connectors are not "legacy" or "old style" except when used in reference to SATA devices. Seeing as how Digium interface cards are not SATA devices, why would you expect them to be using a SATA connector? Its not Digiums fault that the PSU you bought doesn't include molex connectors. SATA uses a different power connector for a few reasons, but the biggest is that SATA supports hot-plugging (assuming your controller, drive, and OS support it), in order for hot-plug to work the drive needs a 3.3V voltage as well as 5V and 12V, molex only gives 5V and 12V. The actual physical connector that molex uses also does not lend itself very well to hot-plugging. SATA power connectors, while there is no real reason that non-SATA devices couldn't use them, they simply were designed for SATA specifically. Personally, I prefer molex connectors for most things simply because they are far more secure than SATA connectors (at least the ones i've used). -- Matt http://www.mattgwatson.ca _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
