Thanks!


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:

Asus and ASRock are still tight so it wouldn't surprise me if that link is correct.

Yet as Moderators here that's dipping into the deep end of technical questions for us. Use one of the below two contacts to inquire on that particular question please.

Both are in CA so PST Time Zone applies.

Support Phone: 1-909-590-8308
Support Email: support@asrockamerica.com



And if you would HP please post back their answer if you would please. That knowledge may prove helpful down the road on a later date to another User here.
