PSU overheats whilst playing games. What is a good PSU without overspending

Hi, depends rather on what other hardware your pc has. As a general rule 450w or 500w will cover most contingencies.

maybe your pc just needs a good clean-up inside, especially build-up of dust on and around fans etc.

If you do go for a new PSU, make sure you check dimensions of your present PSU, so that any new one fits your pc.

>PSU overheats whilst playing games. What is a good PSU without overspending

I would say that its not a good idea to cut corners when it come to the cost of a PSU. Personally I tend to think of the expense of a PSU as investment as opposed to a necessary item required to run a PC. While the wattage the PSU provides is very important, the quality of the PSU should come a very close second. I'd certainly sacrific the wattage in favour of a better quality PSU if necessary/possible.

If renewing a PSU check:

1. The physical size of your PSU, some are hard to replace due to being a non standard size.
2. The amount of power need from the PSU don't skimp

1. Physical Dimensions

Besides the specs and form factors, the physical dimensions are also important factors in selecting a compatible power supply. Here is an outline of the physical dimensions of most standard power supplies:

# ATX: 6x3.5x5.5", HxWxD. Most common. Uses 4 mounting screws.
# Mini-ATX: 5x3.5x5", HxWxD. Rare size. Uses 4 mounting screws. Can be used in a regular ATX case, but often not the other way around.
# MicroATX: 5x3x4", HxWxD. Use 3 mounting screws. Not interchangeable with ATX or miniATX.
# Flex ATX: Even smaller than Micro ATX. Various sizes according to case specs; often not interchangeable.

Use the data above to determine if a particular power supply would fit your case.

The quality of a power supply can be estimated by its weight. While this is not a true scientific or thorough measurement of the power supply reliability, it is nevertheless a very simple and easy way for ordinary PC users to estimate and compare the quality of a power supply.
