Choosing power supply, how to get the voltage and current ratings?
I need to power this fan which is rated at 12 V, 0.95 A, 11.4 W. I am unfortunately without a DC power supply, so I am wondering how I could power this fan using an AC adapter.
I am looking to purchase an AC adapter with variable voltage output, but I can only find ones at my local electronics store that are rated at 0.8 A or 1.2 A.
First question is: since I can't find one of these rated at 1 A, should I go with the 0.8 A or 1.2 A?
Second question is: where do I get Vdd and GND from a tip that looks something like this? I would like to have voltage and ground supplied to a breadboard so that I can supply the fan.
