How Do I Know If My Ps3 Need A Power Supply What Kind Of Power Supply Does Ps3 Use? ?

What kind of power supply does ps3 use? ? - how do i know if my ps3 need a power supply

I have the yellow light of death and it seems that food could be a solution and do not do as an expenditure of $ 150 to it because the use out of warranty service, what type of power source can? Can I say, CompUSA and buy food for a PC and connects to the PS3 or is there a certain type or the connection, I must get? If the source of exploitation does not mean that I am back and you pay $ 150 and you can repair it from Sony. Thanks in advance
