No, all PSUs are not the same size. In fact, there is a wide range of PSU sizes available on the market. The size of a PSU is typically determined by the number of internal components and the wattage rating.
For example, a high-end gaming PC may require a larger PSU than a basic office PC.
Are All Power Supplies The Same Size?
No, all power supplies are not the same size. There are many different factors that can affect the size of a power supply, such as the make and model of the device, the wattage, and more.
That said, there are some general trends that can be observed when it comes to PSU size.
For example, lower-wattage PSUs tend to be smaller in physical size than higher-wattage models. This is because they don’t need to accommodate as many components and thus can be more compact.
Additionally, modular PSUs (which offer removable cables) tend to be larger than non-modular units since they need extra space for the connectors.
Ultimately, it’s impossible to say definitively which type of PSU is “best” in terms of size. It really depends on your individual needs and preferences.
However, if you’re looking for a small form factor unit, then you may want to consider a lower-wattage or modular model.

Do All PSU Fit All Cases?
No, not all PSUs fit all cases. While most PSUs are the same size, some cases have unique form factors that require a specific PSU. For example, many ITX cases use a SFX PSU, which is smaller than a standard ATX PSU.
If you’re unsure whether or not a particular PSU will fit your case, it’s always best to check with the manufacturer beforehand.
Are PSU Standard Size?
There are a few different types of PSU form factors, however the most common is what’s known as an ATX12V power supply. These typically come in two sizes: standard and mini. Standard ATX12V power supplies are designed to fit into a regular sized ATX case, while mini ATX12V power supplies are designed to fit into a smaller form factor case.
The majority of PSUs on the market today are standard size, however there are still some mini units available.
Are PSU Sizes Universal?
PSU sizes are not universal, but there are some standards that most manufacturers follow. The most common size for a PSU is ATX, which is 12″ x 9.6″ x 3.5″. However, there are many other sizes that are used in different computers. For example, the microATX standard is 9.6″ x 9.6″, while the mini-ITX standard is 6.7″ x 6.7″.
Do All Power Supplies Fit All PCs?
There is a lot of confusion when it comes to PC power supplies and whether or not they are all compatible with each other. The simple answer is that yes, all power supplies will fit into any PC. However, there are some caveats that you need to be aware of before making your purchase.
First, it’s important to know that there are different types of power supplies available on the market. The most common type is the ATX power supply, which is what most desktop computers use. However, there are also smaller form factor power supplies available for laptops and other small devices.
Second, you need to make sure that the power supply you purchase has the correct connector for your particular PC. For example, if you have an older motherboard with a 20-pin connector, you’ll need to buy a power supply with a 20-pin connector as well. Newer motherboards typically use 24-pin or 8-pin connectors, so make sure you get the right one!
Finally, it’s always a good idea to check the maximum wattage rating of your power supply before making your purchase. This information should be readily available on the product listing page or on the manufacturer’s website. Make sure that the wattage rating of your chosen power supply is equal to or greater than the wattage rating of your computer’s components combined.
If it isn’t, then you risk damaging your components by running them at too high of a voltage!

PSU Sizes
There are three basic PSU form factors: ATX, BTX, and SFX. The most common is the ATX form factor, which is what you’ll find in a majority of desktop computers. BTX is less common, but is slowly gaining popularity.
SFX is the smallest form factor and is mainly used in small-form-factor (SFF) PCs and HTPCs.
Now that you know the different PSU form factors, let’s talk about PSU sizes. In general, there are two size categories for PSUs: standard and modular.
Standard PSUs are usually larger than modular PSUs since they have all of their cables permanently attached. Modular PSUs, on the other hand, have detachable cables so you can remove any unused ones to help keep your PC tidy.
When it comes to actual dimensions, PSUs can vary quite a bit depending on the form factor and size category.
For example, a standard ATX PSU will typically be around 150mm x 86mm x 140mm (WxHxD), whereas a modular ATX PSU might only be 125mm x 100mm x 63mm (WxHxD). So as you can see, there can be quite a difference in terms of size between different types of PSUs!
Now that you know all about PSU sizes and form factors, you should be able to pick the right one for your next PC build with ease!
Conclusion
No, all PSUs are not the same size. In fact, there is quite a bit of variation in PSU sizes. The most common PSU size is ATX, which is used in most desktop computers.
However, there are also smaller form factor PSUs available for use in smaller computers and devices.
