So based off of various things I've read both here and elsewhere, I'm having the following thoughts regarding power draw:
1. The person who posted that around 2.5W should be the target for the ssd is a mod of the forums and has enough rep to be labeled as a Founder. Whether or not they actually are a founder of the project I don't know, but regardless, I'm inclined to treat that 2.5W number as gospel truth.
2. Having said that, "the 3.3V regulator which is responsible for supplying the NVMe adapter can handle up to 8.25W momentarily, and isn't put under significant load by much else in the system" is very exact, so I'm also taking that at face value, which leads me to the conclusion that 8.25W is the absolute maximum power draw allowable for the SSD. Additionally, the SSD should idle and operate below 2.5W in most cases.
Regarding @zaius 's comment that
This is true. They don't include it in the specs. But they SHOULD include at least some of the numbers in the datasheet, which can usually be found hidden away in a PDF at the bottom of the product page. I've only looked at one such sheet so far, and it only contained "typical" values for "Active" and "Slumber" power modes, so your mileage may vary on what values you manage to find. But, it's definitely a starting point.
