Can I see what power supply I have without opening computer?
No, not unless you can read the label information from outside the case, and I don’t think that’s possible. Unlike the motherboard or processor, the PSU isn’t intelligent, so you can’t run software that will interrogate it and find out what it is. You have to open the case and read the label.

How do I check my power supply 12v rail?
From Advanced mode, go to H/W Monitor, scroll to the bottom and find the voltage readings. If you see a “M.I.T” option select it and go to PC Health Status. Otherwise, go to Home and find the voltage readings on the right side. The 12v rail should read between 11.8v and 12.4v .

How do I find out my power supply wattage?
Steps
The number of watts is equal to amps multiplied by volts. That’s it! For example, if the current is 3 amps (3A) and the voltage is 110V, you multiply 3 by 110, to get 330W (watts). The formula is P=3A X 110V = 330 W (with P standing for power).This is why watts are sometimes called volt-amps.
How many rails Does my PSU have?
Normally the Power supply unit includes the three basic rails which are +3.3V, +5V and +12V. These wires are actually called as Rails. There are several wires that carry the specific voltage to the electric components and all those wires are tied to a single rail in the PSU.
