First question is what country are you in? Any power supply rated 5V and at least 2A and with the correct connector would be suitable. Something like the below would work:

My friend said if i connect it Gpio the current dosnt regulate by orange pi. So i will connect it standart 3.5 mm dc jack. Probably this will solve my problem

Not easy to find in Turkey maybe RS Components or somewhere similar. Alternatively you can order from the Aliexpress shop of Orange Pi. Please at the link if you want to buy in Turkey:

The biggest problem with power supplies is that you need a stable 5V output. Many phone power supplies do not have a stabilized output, this results that the voltage drops below 5V, even that they are rated eg. 5V2A. That makes it a bit complicated to choose the 'right' power supply.

I use a 6 port USB power supply rated 5V8A. This works fine with my OPI PC. Other users reported that PSP power supplies work. I did try a Chinese copy of a PSP power supply and that will not boot, even that it gives a voltage of 5.18V measured at the 5V rail (GPIO). After testing it with a adjustable power resistor I found out that it delivers only 0.324A. So that is one example of any 'fake' power supplies. My OPI PC works too with a lab power supply adjusted to 5.00V output.

The problem with many power supplies offered on Aliexpress is that many do not live up to the specs. Eg. you order a 5V2A wall charger (power supply) and after it arrives you find out that it cannot deliver the 2A. I did open one of those and found out that the components only can do 0.5A (500mA).

I would not buy a power supply of Xunlong (official OPI shop) at Aliexpress, as he gives NO WARRANTY on any of his products! We are still waiting on a response of them to the warranty subject...
