One of the key parts to planning a system is understanding your predicted power needs and doing a power audit. The problem folks have is finding the data they need to do this so I thought it might be worth folks sharing to make it a bit easier
I think it needs to include a good description including model numbers where appropriate. Also not if your data is measured or estimated
Here's some info I've estimated
