Subject: Maximum PCIe slot power draw for X99 Taichi
Posted: 11 Feb 2017 at 10:15am
The specs quoted in the Asus link are simply those of the PCIe specification, which must be adhered to by any mother board manufacture.
Please note that the 75W of maximum power is a combination of the +12V and +3.3V rails. Also, there seem to be some restrictions on power limits depending upon the particular card being used.
See Power and Pinout sections (just above Power) in the link below for details on the PCIe power specification:

I am using some I/O accelerators that can use a bit more than 25W but will not unless I change a setting. I don't want to change the setting until I confirm if these slots support up to 75W. I am looking for a statement similar to what Asus has posted here: https://www.asus.com/support/faq/104406/. I didn't find anything in the manual or FAQ. Thanks! |
