Yeah, true... Aiming for 100% overhead is never a bad idea with ebay power supplies! smile

Heatbed and E3D on full power on my machine and it runs about 20A (12+8A respectively). There's a bit of variation, but I'd still be pretty confident a 30A rated unit would manage that peak and the somewhat lower long-term continuous.

Power is voltage x current, so in the above example 12 x 0.18 = 2.16W

The 360W supply you've shown is more than capable of running the printer, and a fairly large quantity of fans!

Even if each fan pulls 330ma that is only adding about 12 watts load to your system.
IIRC my stock solidoodle only pulls about 120 watts.
Ohms law is your friend.
