24 A 30A 18A 18A 18A 18A 0.8A 3A

That unit will be fine for a GTX 560, it doesnt have 72A on the 12V rail, it has 41A. Based on the description im pretty sure its a 550W S12Energy+ as that is the only Seasonic in that power range that i can find with 4 rails. If you look at the load table they give the 12V source that powers the rails a max rating of 41A.

I commend you on your choice. That is the PSU which I have in my PC.

The Seasonic S12 550 is more than. The 18A for each 12v rail represents the peak amps, not constant amps and not all 12v rails can peak at the same time. Actual maximum amps across all 4 rails is 41A.

Just as long as you don't plan on adding another GTX 560, you're fine.
