More often than not, also depending on the type of PC lover you are, you will find that it is mostly the Graphics card that will use most power. Unless you have a built in grahpics card, then it will most likely be the motherboard.

Which computer component presents the most danger from electrical shock?

The computer component that presents the most risk of electric shock is the power supply. Since there are large capacitors in the power supply, it is possible that you might get shocked, even with the power supply unplugged.Another component that presents a shock risk is an internal modem. You might grab a hold of it while there is an incoming phone call, and then get shocked from the ringer current.

Is power supply an input or output device?

A power supply unit (PSU) converts mains AC to low-voltage regulated DC power for the internal components of a computer. PSU is a output device because it is outputting power to the rest of the device. Most personal computers can be plugged into standard electrical outlets.


At what temperature do computer components fail?

For the most part, today's integrated circuits will start to exhibit significant issues when their internal temperature rises about 80 degrees Centigrade, or if they are subjected to freezing temperatures below -15 C.However, the exact thermal profile is highly dependent on the specific component. So much so, that the above generalization is likely only valid for today's Desktop systems.
