One of TFT monitor power supply controller has failed. In Desktop computer CPU Type SMPS both 5 Volts as well as 12 volts both are available. But, it has very high current e.g. 15 to 30 Amp. for 12 volt line as well as in 5 volt line and accordingly its wattage are computed, for example 250 watt, 300 watt, 600 watt etc. The TFT power consumption is much less than computer desktop CPU consumption. I want to use an SMPS supply's 5 volt and 12 volt line for TFT Monitor. This will a stand alone supply other than CPU. I suppose that even the TFT panel use less power, despite of the SMPS will consume full power, but since the voltage are in pre-defined required range i.e. 12 and 5 volt hence it should not damage other components. Please share your opinion or experience if someone already did it before.
It would be interesting to know what interests you. If you have 5V or 12V and 30 A, this is an electric welding machine, but nothing else. But as you know, the current in an external circuit is determined by the resistance of that circuit (you may remember something about Ohm's law about the external circuit).
Thanks Kaljukass. Perhaps my wording is incorrect. Please have a look on the specification of i-ball SMPS. It is only a 400 Watt SMPS and as per its specification the maximum output is 360.1 VA. What I want to know is if there is any components which is specific to current limit and due to receiving higher current it may get damaged. TFT Monitor only required 1.5A with 230V AC.
If your system is working as should, ie everything is OK, then all you need to do is make sure that the output voltage of the power supply is what your consumer needs and that the power supply can give the minimum power that your consumer needs. If these 2 conditions are met, nothing will ever happen. So the output voltage of the power supply must be what you need (very important!) and it must have at least as much power as your device needs (the power supply can always have more power, but not less). If everything is so, everything is fine. NB! If you are not very familiar with electrical matters, try to find a local electrician (electronicist) who knows exactly what and how you can do or you must do and who can help you, or use only the equipment recommended by the manufacturer.
