2 Easy Ways to Know What Power Supply do You Have

If you want to know your power supply, you have come to the right place because I will tell you two easy methods to know what power supply do you have. Unlike the software’s that your GPU and CPU specifications, there is no specific software to know about the power supply you have.

Why you should know about What Power Supply do You Have?

The primary question is, why should you know about the details of your power supply? Well, the answer is simple. It is essential to know about PSU when you want to upgrade your graphics card or any other major component. When adding a new component, your CPU will require more power to handle it.

When the power requirements of your CPU increases, you will need a power supply with higher wattage. Using a low wattage power supply can damage your components. This is why you will need to change your PSU for more power as we said earlier that no software could detect this.

So, in that case, we have come up with two methods to help you out. First of all, see the statements below and tell us which one is right for you?

  • Did you build your PC by assembling different company’s components?
  • Are you using a pre-built computer straight from the PC market?
Note: Some premium power supplies from high-end manufacturers come with software that can be used to monitor and manage the fan speed, temperature, and power.

Let’s find about how you can find out the specs of your PSU.

What Power Supply do You Have

First Method

Whether you have a pre-built or an assembled computer via different components, the most conventional method to manually know about the power supply is to open the chassis side panel manually. Most of the companies mention the power supply specs. But nowadays some premium companies don’t mention power capacity on them in big fonts. But the specs of the power supply will always be written on one side.

The specs may be written on the other side where you can’t see. If it is, on the other hand, you have to plug out the power supply to see the specs. It is not very difficult to unplug the power supply.

Reading the specifications of PSU

You can find the following specs on every PSU:

PSU Name/ Model – You will find the company’s name, PSU model number, wattage, AC input, and DC output. Below is the image of TX650W specifications.

AC Input

It is the amount of AC voltage the power supply needs to operate. For Europe and the USA, it is from 110V – 17V, and for Asian countries, it ranges between 200V to 240V. Some power supplies can operate in all of these ranges, and they usually have a switch mechanism to choose a voltage range in your area.

DC Output

It is the amount of DC voltage the power supply provides your CPU. Standard DC outputs (also known as rails) are +3.3V, +5V, +12V, -12V and +5VSB. The +5VSB is a standby voltage and is always on to power keyboard, mouse, memory, and BIOS when PC is in standby mode. It is also used to turn on the PC and provides a small amount of current even when it is turned off.

Max Load

Every rail has a maximum load it can provide. For example, +12V rail has a maximum current of 624 watts, and it cannot offer more than this. If you overload your power supply by adding more components than it can handle. Chances are it will result in a PSU failure or a shutdown.

Maximum Combined Wattage

It is the maximum power of all the rails combined. In TX650W, it has the max combined wattage of 650W. So, it is the maximum load TX650W can handle.

Total Power

This is the total power a PSU can provide, which is measured in watts. Some companies add the combined total power of all rails, but some companies only mention the +12V rail power. Because it is the most important one and has most of the power coming from. It powers most of the CPU components like processor, GPU, fans, or hard drive.

PSU Connectors

Below is the image of the most common connectors used in a PSU.

Second Method

This method is more comfortable than the first one because you won’t have to open up the PC case or unplug the power supply. Because if you have purchased a pre-built model, then the chances are that the company has mentioned all the specs on their product page. There you can also find the specs of your power supply.

Wattage capacity is the most crucial thing to look for in a power supply. If you run any specific graphic card on your system, you must first know if there is any capacity for an upgradation. 

Power supply quality

There are some cheap and premium power supplies available in the market. Premium does not indicate exclusively expensive power supply, but here I’m referring to the special ones made for gaming. For example, PSU’s made by Cooler Master, Corsair, EVGA, Antec, and Thermaltake. Best quality cables with sleeves are applied in PCU’s. PCU’s are heavy and mostly have a black body. Graphics card power connectors are incorporated in them. 

What Power Supply do You Have

Cheap power supplies are generally light in weight and have a cheap shiny aluminum body. Intex and Zebronics are companies that make cheap power supplies. Less power supply cables are incorporated in them compared to premium, and most of the time, cables don’t have sleeves.

If any time you have the thought of upgrading your PC, you can analyze power supply by only these two methods. Most of the time, the only choice is to open the system to know about the power capacity, making everyone reluctant. So, by reading this article now, you know the methods to check what power supply you have.

I love gaming and i have been playing since the Atari and Sega were released. My love for gaming made me build this website where i talk about everything related to gaming.
