1.How many connectors linked your original power supply to the motherboard?
Answer: 2, 1 P1 connector and one auxiliary 4 pin.
Motherboard Power Connectors
Every PC power supply has special connectors that attach to the motherboard, giving power to the system processor, memory, and all slotted add-on boards (ISA, PCI, AGP). Attaching these connectors improperly can have a devastating effect on your PC, including burning up both your power supply and motherboard.
2. How many watts of peak power could the original power supply provide?
Depends on make and model. If you just open the side panel of the computer and look at the box on top were the power cord goes then it should say there.
3.Why is it important to calculate the peak power required for all components?
The peak power requirements typically have a very minor impact on power supply average operating component temperature and so have little impact on lifetime. Understanding peak power allows you to optimise your power supply selection.So you don't get a power supply that is too big or too small.
4.What are two reasons that IT technicians don’t usually repair a power supply?
The reason that PC technicians don't usually repair a power supply is because
1.there are high voltages present posing harm and it is not worth the time to repair them.
2.Because nobody is willing to pay for it, but everybody are happy to exploit it. Power supply repairs are time consuming, tear down, investigation, resoldering, tuning and testing. End cost is greater than a price of new power unit. Plus there are high risks involved. While dealing with a power supply technician has to work with 110v or 220v power, which is dangerous n its own, but there are greater financial risks as well. When repairing a power unit in a PC, you basically give an excuse to the owner to blame any other unrelated problem that will happen with the PC on your work. There are a certain group of customers that when a motherboard or ram stop working, the first thing they will do is call a technician and tell them that because of their repair the PC stopped working and demand payment or brand new PC. I had guy who once wanted injury compensation, because he claimed he got electrocuted by a printer where I changed a drum module, in case of power supply repair this probably will happen even more often. They do that anyway even with a simple module swap repair as well, but in this case technician has easier ways of proving that it is no his work that is the root cause of a new problem
5. What term is used to refer to components that are commonly replaced but not repaired? 6. What is the most efficient way to determine whether your power supply is bad?
Answer:
Field Replaceable Unit (FRU)
In electronic hardware, particularly computer systems, a field-replaceable unit (FRU) is a circuit board or part that can be quickly and easily removed and replaced by the user or by a technician without having to send the entire product or system to a repair facility. The defective unit is found by standard troubleshooting procedures, removed, and either discarded or shipped back to the factory for repair. The new unit is installed directly in place of the defective one.
The FRU scheme is often the most cost-effective way to maintain complex systems, and is a major motivating factor behind the evolution of modular construction. When backed up by good parts availability, knowledgeable technical support, and reader-friendly documentation, this approach can minimize system downtime and optimize reliability.
