But i didn't get the power supply and i do have the power cord from the macbook to the power adapter.
Assuming that means you have the magsafe connector and you're just going to try to splice it onto one of the power bricks you have, I'd probably go with the 15.9v at 3.6a one presuming it's not some generic chinese brick. I think it would be more than close enough to work temporarily.
Also, I'd probably chuck that universal one you have or possibly use it for ultra cheap laptops at the very most. Those things are usually built extremely poor with as little shielding as possible, universal bricks as well as any generic chinese brick can cause quite a bit of RFI depending on how many corners they cut.
