The simplest way is that most power supplies have a built-in fan (or several) to keep them cool. If this fan is blocked, or the case airflow is going opposite to the power supply airflow (which typically pulls air from the case, out the back) then it can cause overheating.
Lowering the power draw on the power supply will also reduce the amount of heat it produces, especially on the 12v rail.

What are the components of a power supply?
Sometimes when people buy a computer power supply unit (PSU), there are several components in the box: a AC power cable to connect the power supply to the wall mains outlet, the power supply itself (PSU) that converts mains power into more useful forms of power, and one or more DC power cables that connect the power supply to the motherboard and other parts of the computer. (On a modular power supply unit, those cables can be detached from the PSU). A computer power supply is in a metal box that is difficult to open, so most people treat a computer power supply (PSU) as a single indivisible component. Inside a computer power supply is a transformer to help convert mains power into more useful forms of power, power diodes and power transistors typically mounted to a heat sink, and other components to help the conversion or to filter the power to meet EMC requirements, and often a fan to blow air on the heat sink to keep the transistors from overheating.
What would cause a varistor to burn?
Overload - excess voltage causes excess current, and the combination causes excess power dissipation, leading to overheating. If the varistor was included to help dampen voltage surges, then a very "dirty" supply. with large numbers of surges, can lead to overheating.
What do you do if the Windows display freezes after startup and the power supply is really hot?
The display is probably freezing because the grafic card or processor is getting to hot. When this happened to me I had to install more fans in my computer case to help cool the system. R. > Check your power supply, It could be bad.

If my computer keeps shutting down will system cooling help?
Yes, it should stop all shutting down actions by your computer if the system is overheating.
What is the working of power supply?
The power supply provides electricity that support current to allow the component to run. For example: (The motherboard) the motherboard is useless without the help of power supply. Any component or hardware were useless without the power supply.
Will using a programmable power supply help me save money?
Yes a programmable power supply will help you save money becsaue you can program when you want the power turn off and when it is turned on, instead of it alwasys being on
Why do you supply DC power?
DC power supply is used to power the IC's and other active and passive devices.It is provide to amplify the weak signal with the help of amplifiers.
What does short to power mean?
"Short to power" is a term used in electronics to describe a circuit malfunction where an electrical short circuit causes excess current flow to the power supply, potentially damaging components. This can lead to overheating, fires, or other safety hazards. Proper circuit design and precautions such as using fuses can help prevent short to power situations.
Is installing an uninterruptible power supply an option for preventing data loss to power outages?
If you having a power outage, you can do one of two things, depending on the condition. If it's just the computer that's going out, it may be that the CPU is overheating, and you need to see if the CPU fan is compatible with the CPU. If it is a power outage in the entire house, you may want to replace your current hard drive with one that will periodically back up your current session. Unfortunately, installing an uninterruptible power supply won't help much; the power supply doesn't create the power, it just converts the electricity into something that the computer can use. So if there is no electricity, the power supply has nothing to convert. Hope this helps! SeanHolshouser
Why is your graphics card beeping?
A beeping graphics card typically indicates a hardware issue, often related to power supply, overheating, or connection problems. The beeping can signal that the GPU is not receiving adequate power, is improperly seated in the PCIe slot, or is failing due to overheating or component failure. Checking power connections, reseating the card, and ensuring proper cooling can help diagnose the problem. If the issue persists, it may be necessary to test the card in another system or consult with a professional.
2000 Jetta 2 liter motor overheating but no heat from vents when heat is turned on Can this be thermostat any help is appreciated?
my jetta keeps overheating so i replaced the thermostat hoping that was the problem but know there telling me it might be the water pump check it out maybe its that
