![What Power Supply Do I Have: Know Your PSU Wattage [2021]](https://hearthstats.net/wp-content/uploads/2021/08/What-Power-Supply-Do-I-Have-Know-Your-PSU-Wattage.jpg){kind=small}
To power a computer you need a good power supply. Not just a good power supply, but a power supply that does its job well. One that provides the voltage and wattage needed to run a machine, and not overvoltage it. Now, if you have a computer that’s not a beastly multi-GPU monster, you don’t need a power supply with a capacity of more than 500 watts. But, if you have a rig with multiple GPUs, or a machine that needs over 500 watts of power, you’ll need a power supply that can handle it.
The PSU Wattage Calculator is a tool that tells you the power consumption and power draw of various PSU’s based on real world testing, and comparing those numbers to your PSU or the PSU you want to buy. This helps you determine if what you want to purchase will meet your needs, and if so, what wattage rating is recommended for that PSU.
Having an underperforming power supply is never fun, and in the future it could be less of an issue. A new standard for power supplies is in the works that will help consumers better understand their power needs. The new standard will help power users understand the maximum power draw of their devices, and will also provide data on how much power can be drawn before the PSU output voltage (the voltage that is provided to your system) hits its limit.
You’ve come to the correct spot if you’re having difficulty recognizing the model and specs of your power supply.
For various reasons, such as installing additional components and overclocking them, checking your power supply’s wattage and ratings is important.
So, what does my psu stand for?
The most simple method to check your PC’s power supply is to open the case and look for the model and specs written on the body or identified on a sticker on the power supply. You may also look at the power supply box that comes with it.
Continue reading because I’ll go over every detail to show you how to figure out what psu you have.
What kind of power supply do I require?
The power supply unit you purchase must be enough for your computer. If you want to update your PC components, you should get a power supply with a greater wattage and rated capacity. Keep in mind that if you don’t utilize a high quality power supply, your motherboard and other costly components may be destroyed.
As a result, you’ll need to choose your power supply carefully.
If the results of any power supply calculator do not satisfy you, you may read our suggested budget power supply review, which will help you decide which PSU to buy.
How can I figure out what kind of power supply my computer has?
Here’s how to figure out the power supply unit you have:
1. Look at the power supply’s label.
On every power supply, there is a label sticker or printed layout with the model number and specs.
You’ll need to open the PC case and search for the written level on the PSU to verify this level on your PC power supply.
If your power supply is hidden by a PSU shroud, you’ll have to remove it to learn more about its model and specifications.
To remove your computer’s power supply, you may need to loosen 4 or 5 screws.
Before touching your computer, unplug it from the power source and switch off the power supply.
Now that you’ve removed your power supply, examine its body to see whether it has any labels, such as the one seen below.
The model number, certified ratings, and all other characteristics of your power supply may be found here.
This is the quickest and most accurate method to determine the wattage of your power supply.
2. Look up PC specifications on the manufacturer’s website.
If you have a prebuilt PC from any manufacturer, you may go to the company’s official website and look for the model number.
The power supply utilized in your computer may be found on the product page for your computer model.
Here’s an example of a product page including all the details, including the computer’s power supply:
This method saves a lot of time and work when determining the wattage of your power source. It’s also useful since the power supply on most prebuilt PCs aren’t labeled.
So, if you Google your computer’s model, you’ll be able to verify the wattage of your power supply within the first few pages of results.
3. Look at the power supply’s box for information.
You may verify the model and specifications of the pass apply box if you have it. An international handbook is included with certain power supply. You may learn more about it and how to install the power supply on your computer by reading the instructions.
For your convenience, I’ve included a photo of a power supply’s box and instructions.
I believe that examining the power supply’s box is the simplest method to determine the wattage, model number, and other necessary information.
Hopefully, one of the three techniques listed above has assisted you in determining what power supply you have.
How can I verify the wattage of my PC’s power supply?
You’ve figured out how to figure out what power supply unit you have so far. But, wouldn’t it be useful if I also told you how to check the wattage of your power supply?
The simplest method to determine the wattage of a power supply unit is to examine the PSU box that came with it when you purchased it. Check the PSU’s specs section. The maximum power of the power source will be shown.
Don’t be concerned if the package is misplaced. I have contingency measures in place for you.
If you have a pre-built PC, go to the official website and look for the power supply that came with it on the product page for your computer model.
By opening the PC case, you can also verify the receipt for the purchased PSU or the label on the power supply.
What Power Supply Size Do I Require?
Knowing the wattage of a power supply and its certifications isn’t enough to address your issues.
Because your power supply may not fit correctly within your PC case, it’s ideal if you also examine its size.
For personal computers, there are three different power supply sizes to choose from. They are as follows:
- Power supplies for ATX and ATX12v
- SFX-L SFX-L SFX-L SFX-L
- Power supply for SFX
The ATX power supply is the finest power supply size. The majority of intense gaming PCs utilize this power supply size.
The ATX power supply are typically 150mm x 86mm x 140mm in size, which is large enough to cool down fast.
The ATX12V power supply is comparable in size to the ATX power supplies.
Pre-built PCs often utilize the SFX12V or SFX-L PSUs. SFX power supply, as well as
EPS12V power supply are mostly utilized in tiny ITX PC designs and other small form factor PCs.
So, if you ask me, I’d say:
What size power supply do I require?
It would be beneficial if you purchased a power supply that is large enough to fit within your PC chassis. If you’re utilizing a mid or full tower PC chassis, an ATX power supply should suffice.
Why is it important to know about your power supply?
There are many reasons to be aware of your power supply’s model and characteristics.
The following are the most important reasons to understand your power supply:
- New components such as a graphics card, RAM, and fans are being added.
- Overclocking is the process of increasing the speed of your computer.
- Without replacing the power source, you may upgrade your whole system.
The wattage and ratings of a power supply are the most essential characteristics.
These, however, are insufficient. You should also know which tier your power supply belongs to, since power supplies with the same wattage and rating operate differently.
As a result, I strongly advise you to review our most recent PSU tier list.
Which Power Supply Calculator Is The Best?
On the internet, there are a plethora of PSU calculators. However, the majority of power supply calculators are ineffective at recommending writing wattage and certifications.
The following are the most accurate PC power supply or PC wattage calculators:
- Calculator for Cooler Master power supplies
- Calculator for Seasonal Wattage
- Calculator for Asus PC power supply
However, I recommend that you review the most recent PSU tier list and purchase a power supply that meets your computer’s requirements.
PC power calculators are internet applications that determine how much electricity your computer requires. However, these programs are primarily intended to promote your particular goods and display large amounts of wattage for marketing purposes.
Purchasing a power supply based on a PSU tier list is thus more efficient than using a PC wattage calculator.
