I came across the Seasonic SS-500ET PSU: https://seasonic.com/et.

On the label it says that it has two 12V rails and that each one provides 17A. Does it mean that anything I connect to it that uses 12V voltage has access to only 17A or that it can have the whole 34A regardless? I'm asking specifically for a GPU that powers from the PCI-E only. Thanks in advance.
 
Solution
Each rail is limited to 17A and they are isolated so you can only get 17 amps max per rail.

....but I'm seeing in that link 46 amps total so 23 amps per rail.
That's not how it works, guys. You don't just add up the +12V rails. The specification on the rail is the "cap" for each rail, not it's capability. If you want to know the total capacity, you look at the wattage listed below the rails (however there may be) and divide by 12.
