Rectifer
A rectifier is a device that converts alternating current to direct current. A transformer is a device that changes the ratio fo current to voltage. A rectifier is found in a PC power supply.
A rectifier is a device that converts AC to DC.A transformer is a device that changes the ratio of current to voltage.A computer power supply functions as both.Answer found in CompTIA A+ Guide to Managing and maintaining Your PC 6th edition on page 154.
A transformer is a device that changes the level of an a.c. voltage, while a rectifier is a device that converts alternating current to direct current.
In the power suply
The PC power supply box's function is to supply the computer with power. Without the PC power supply box, the computer would not be able to turn on and off.
The rectifier is what changes your AC into DC that the computer can use. Transformer raises or lowers the voltage. So you have 110 volts AC coming into your computers power supply. The Rectifier circuit in there changes the AC voltage to DC voltage but it is still to high for the computer use. The transformer lowers that voltage down to the various voltages that your computer needs
There is no transformer used in PC power supply. There is rectifier used to rectify or convert AC input voltage into DC output voltage.Transformer based rectifier produces some spikes at the output DC voltage, hencethey uses SMPS (Switch Mode Power Supply) to avoid spikes to the output DC voltage and get a smooth DC voltage.

Oh no i suggest you buy a new power supply before it complety stuffs your pc. you may not have enough power in your power supply to run it.
Unplug it from the power supply.
Keep it plugged in.
change the power supply then restart your PC......
