No enough information provided to answer. There are all sorts of Power Supply Units out there, you haven't mentioned either the output of the supply (voltage),if there is a driver, or the LED in question. LED's are non-linear devices, so that small changes in applied voltage once you reach nominal Vf result in huge changes in current draw. If you have a supply with overcurrent protection and the voltage on the supply is appreciably above Vf, you are likely to trip the overcurrent protection, and get no output at all. If it is a linear supply, if you don't burn it up with the overload, the load will probably drop the output voltage enough to reduce the current to roughly 3000ma. If there is a driver involved, it is going to depend upon the design of the driver. IF the driver is rated at 3000ma, 3000ma is all it is going to put out, and it will deliver just enough voltage to the LED to drive it at 3000ma. In any event you are not likely to get 3500ma out of anything that is designed for 3000ma, whether the it works at all is going to depend upon information you have not provided.
