It is important to know what your PSU wattage is, and how it relates to the rest of your computer components. There are many different types of PSUs that can be used with a variety of computers, but knowing what you have installed in your machine will help you decide what type you need for replacement or upgrading purposes. This article gives an overview of power supply units and provides some tips for determining which one is right for you.
What PSU Do I Need?
Everyone has a different requirement for a power supply. Knowing your PSU wattage will give you an idea of what type and size is right for you, but there are many other factors to consider when purchasing one too.
As with any hardware purchase, it’s important that the power supply be compatible with the rest of your system in order to work properly. The power supply’s wattage and power type need to match what your system is running on.
Let’s take a look at the different types of PSU: switching, linear-regulated, dual rail, or single rail?
Switching PSUs are designed for computers that require loads with varying amps (i.e., CPUs). Switches allow you to quickly change between two voltages sets without having to switch out an entire power cord. This saves time during installation while also making it easier when upgrading components in the future because there will likely be higher voltage requirements than what was available before. Linear-regulated PSUs provide a constant voltage which can result in lower amperage draw but may not have as many features like protection against overloading and short circuits.
Dual Rail PSU
Dual rail PSUs provide two different voltages and are typically used for higher-wattage systems that need to distribute power evenly between components such as CPUs, graphics cards, RAM modules, etc.
Single Rail PSU
Single rail PSUs function like dual rails but deliver the full wattage through one wire instead of splitting it in half (for example a 600W PSU would become 300W on each side).
PSU Wattage: make sure you know what your computer consumes and buy accordingly! A rule of thumb is any PC with an Intel Core iX series CPU needs at least 500 watts which means if you have multiple other parts plugged into this system or plan on upgrading soon then go ahead and purchase something more powerful like 700+.
How to check what power supply I have on my PC?
Here are the steps to find out what power supply unit you have:
Check the label on the power supply
You can check the label on your power supply to determine what wattage you need.
If the label isn’t there, or if it’s not in English, check the physical size of the power supply
The second way to find out what kind of PSU wattage you have is by checking its physical dimensions. In addition to looking at how big it is, also take a look at where all of its cables are connected – that will tell you which type of connector setup it has and how many watts they can provide when combined together.
Search for PC specs on the manufacturer’s website
You can search on the manufacturer’s website or the company that sold you your PC to find out what kind of PSU they recommend.

You can also use our power supply calculator and compatibility chart to find exactly which PSU will work for your system.
Find out the power supply details on its box
Find out the power supply details on its box. This includes what kind of wattage it is, how many amps are available for 12V power, and the number of pins inside.
This will give you a sense if this PSU can provide enough power to run your system without any problems. Also take note on how many connectors there are (i.e., SATA, PCI-E) as well as their size/shape and orientation in order to make sure they’ll fit with your setup.
It’s also important to know that while some PSUs have modular cables which allow you to detach or add additional ones based on need, others come pre-wired from the factory so be mindful when making a purchase decision whether you want fixed cable connections or not before buying one.
Another thing worth mentioning: not all PSUs have a power switch. So if you’re looking for one with that function, be sure to double-check what kind of connections it has – either on the back or in the front panel (or both).

Additional Content: There are some other things worth mentioning about your CPU/GPU system which might not always reflect so much on what type of PSU wattage is needed but will make the decision process easier nonetheless. These include number and type of peripherals connected to system as well as their specifications like watts and amps.
How to check PSU wattage on PC?
You can check the PSU wattage back of the power supply case. This label also includes what type of connector is on that particular cable, e.g., a PCI Express connector or SATA Power Connector, and what kind of wire size it can support (20AWG for example).
You will want to make sure you have more power than you need. For example, if you are running a CPU that is rated at 250 watts and have a 400-watt supply, then 100 of the wattage will not be used.
What Size Power Supply Do I Need?
Everyone asked what size PSU they need and what wattage is needed for their system. This question can be a little difficult to answer because some PCs are designed with specific PSU requirements, while others have more general guidelines on things like minimum power supply ratings.
In order to ensure compatibility, it’s best if you know the PC model number before buying your power supply unit (PSU wattage). If this information isn’t available when you go shopping then ask an associate in store or use our online chat service as we will happily help!
Most of us don’t want any surprises after opening up our new computer only to find that it doesn’t work properly due to size incompatibility issues; so take note of these dimensions before heading out:
There ar mainly three power supply size available for personal computer: They are given below
ATX and ATX12v power supply
ATX12v is a standard specification for the form factor of computer power supplies, it was designed to replace ATX by Intel. Power Supply Units (PSU wattage) are devices that convert electric current from alternating current (AC) into direct current (DC).
SFX-L power supply
SFX-L power supply is an old ATX power supply specification that has largely been replaced by the SFX-L form factor.
The standard (PSU wattage) is a computer power supply which converts alternating current from mains electricity to low voltage direct current for use with personal computers and their components.
It provides options such as: 120V, 230V, or 220V.
SFX power supply
SFX power supply is a type of power supply that is designed for small form-factor PCs, including Mini ITX and MicroATX based systems. SFX power supplies are smaller than ATX units and produce less noise to make them ideal for quiet PC builds.
SFX power supplies can be 60W or 100W and come in passive or semi-pass ive designs.
Why know about your power supply?
You always have to know what wattage or power supply you need for your PC. The difference between a 400W and 750W PSU wattage is huge, so it’s worth knowing which one you have in case the specifications are not on your computer box.
Know Your PSU Wattage:
– You always want to know what wattage (or power) you need for your PC – often this information is NOT on the side of your PC because many computers nowadays come with generic parts inside them that differ from model to model. Knowing what watts you need can prevent future problems! It might also be helpful if you have an old desktop tower at home, but don’t remember how much power it needs – just check out its specs online beforehand before buying a new PSU!
Know Your Tiers:
– Some people also want to know what tier they’re using. Personally, I don’t find it that important because most modern PSUs are good and produce the same quality of power. However, if you have a custom PC with high end parts in it or really want to maximize your performance for gaming purposes then knowing what tier is best can be helpful!
Which Is The Best Power Supply Calculator?
The best power supply calculator is the PC Power & Cooling 80 Plus. It can help you to learn what your PSU wattage should be for an efficient and stable build with a specific computer case, motherboard, graphics card type, CPU type, etc. This way you will have peace of mind that your new rig won’t overheat or burst into flames!
– How many watts does my PSU wattage need? A good rule of thumb is about 250W per drive bay in the system (or one 110mm fan). For example: if you’re using two 120mm fans and three hard drives then it’s likely around 350 – 400W would be enough. If these numbers seem high then consider going with all SSDs instead as they
Frequently Asked Question
Question: How do I check my power supply?
Answer: You can’t actually “check” your power supply because it’s an unseen part of the computer. You need to look at what is coming out from the power cord and what you are plugging in to make sure they match up. If you have a laptop, there should be some labels on its side that tell you how much wattage it needs.
Question: What is a power supply?
Answer: A power supply’s job is to regulate the electric current and convert it into usable voltages for different components in your computer such as the motherboard, CPU, hard drive etc. A PSU will also provide PWM (Pulse width modulation) to control what percentage of power is being supplied to the computer at any given time.
Question: What’s a good PSU?
Answer: A lot of it depends on what you need, but generally speaking most people will say that 700-1000W should be enough for gaming and other regular use in 2018. And if your PC has high-end graphics (like a gaming video card), you might need even more.
Question: What is the difference between watts and volts?
Answer: Power in your home or office comes from electric power grids that are regulated at 110-120VAC, but what gets to your computer’s PSU has to be converted into something like 12VDC for it to work .
Question: How to tell if your power supply is bad?
Answer: If you’re experiencing any of the following issues, your power supply might be bad:
– Computer is not powering up. – The computer powers on but won’t boot into Windows. – Random shut downs or reboots while playing games (random BSODs).
Question: What does “fanspeed” refer to?
Answer: The amount of air blown by the power supply’s fans.
My final thoughts are that the power supply is a component in your computer system that you need to know about, but don’t worry. It’s not complicated and if you follow these steps, it should be easy for you to find what PSU will work best for your needs.
