We are designing a product which needs to provide data and power to an SSD connected using SATA. However, we cannot find a specification of the power requirements for a SATA connector. How much power should a power supply behind a SATA power connector provide at a minimum?
I have acccess to the SATA specification. However, we did not find a specification of a minimum power supply. It only mentions the 1.5 A rating of the individual pins. It seems to define how to deliver power, but not how much.
I found an answer on power connector pins and the wikipedia entry on SATA power connectors. However, it seems to me that the 1.5 A specified there is the minimum the connector should support. That is, the connector should not melt if I put 1.5 A per pin through it. I don't think it means the SATA device connected to it can expect 1.5 A per pin to be supplied.
