What is a power supply in a PC?
A Power Supply Unit (PSU) is an internal IT hardware component. Specifically, a power supply converts the alternating high voltage current (AC) into direct current (DC), and they also regulate the DC output voltage to the fine tolerances required for modern computing components.
What is a power supply and what does it do?
Power Supplies Convert Power Power conversion changes the incoming electricity to a format that the electrical device can use. Two types of power supplies exist, DC-DC and AC-DC. DC-DC power supplies allow you to plug in electrical devices into car outlets or similar sources that supply direct current, or DC, power.

How do I choose a PC power supply?
If there is a sudden demand for more power, your PSU should be able to handle the higher output briefly, but should not be expected to run at those higher wattages continuously. Always make sure the PSU you purchase has sufficiently high continuous power output, and don’t choose solely by peak power capabilities.

How does power supply affect PC?
Different components within the computer require different levels of power. Therefore, a power supply carefully partitions power at the different levels. The computer doesn’t operate any faster or slower depending on how many watts the power supply delivers; either it has enough to run, or not.
Why are PC power supplies so big?
In servers, size is a constraint – we want to fit as much server in as little datacenter as possible. As a result, their supplies tend to feature much, much higher power densities.
Can you have too big of a power supply?
There is no truth to the myth that a large wattage power supply will force too much power into your devices causing overheating and burnout. The power supply will only provide the needed wattage. For example, a device that needs 50 watts will only get 50 watts from a 250 watt supply, not the entire 250 watts.
Is 600 watts enough for a gaming PC?

Is PSU and SMPS same?
A PSU on paper usually does not supply power, it only converts it. Its typical application is to convert a utility’s AC into required regulated DC rail(s). Depending on the mode of operation of the semiconductors, the converters can be linear or switching. SMPS stands for switch mode PSU.
What happens if power supply is too weak?
If your power supply is too weak then it will not give enough power to your cpu , your pc might not turn on and also it can crash between your work . So give a decent psu which gives your cpu enough and good flow of current into the components.
