HardcoreGames Posted November 28, 2021 Share Posted November 28, 2021 (edited) On SATA specs before v2.3, that pin was supposed to be always powered even though the drives didn't use it. With 2.3, they chose to have it only be powered when you are restarting the drive. Up to version 3.2 of SATA, pin 3 of the SATA PWR connector was specified as 3.3V, but as of version 3.3,it was changed to a PWDIS (Power Disable) pin to improve compatibility with SAS. So is my AX1600i compatible with the latest SATA version and support the PWDIS? Edited November 28, 2021 by HardcoreGames Link to comment Share on other sites More sharing options...
