Zimaboard internal power supply

Hi there,
has anybody information regarding the internal power supply (5 VDC & 12 VDC SATA connector) of Zimaboard?
What are the maximum current ratings of these two voltage rails?
I want to connect two 3.5" SATA HHDs, each of them with a power rating of +5V/0.75A and +12V/0.6A and I have to be sure that Zimaboard is capable to supply them reliable, even at higher load.
Is it possible to increase the power ratings on this connector by using a power supply with higher performance than the original power adapter (12 VDC/3A)?

did you have some issues with mounting HDDs ??? ive noticed something strange that feels like a kind of undervolting.

Hello, Because the HDD consumes too much power instantly (for example, it may require 2A of current at startup, please refer to the specification for details), the included power supply can only provide a maximum of 12v 3A total 36W of power, which may cause insufficient power supply at the moment of startup. As long as the voltage meets the regulated output of 12v, you can choose a higher power supply to meet your project needs.

Hello CainZzz, thanks for your reply and for clarifying, I will check this.

Best regards, Norbert
