I want every part of my computer to be in optimal condition, whether I’m using it for online browsing or intense gaming. The power supply unit (PSU) of my PC is crucial for its operation.
For example, my PC won’t function if it doesn’t have enough electricity. Instead, the right amount of power must be distributed throughout the PC’s components, including the GPU, CPU, and sound card.
So, I need to make sure the PSU is strong enough for the job if I wish to add a high-power graphics card. I should examine my PC’s power supply before installing components that consume a lot of energy and might not function properly.
This article will clarify how to know what power supply you have? Let me quickly give you a quick answer: The simplest approach is to look at the label on your power supply.
Usually, it displays the highest power it can produce, signifying the PSU’s capability. Now let’s move towards the step-by-step guide of how to know what power supply you have.
How to know what power supply you have? Step-by-step Guide
Checking my PC’s power supply is trickier than inspecting other components like RAM – that’s one of the challenges I often face. Unlike installing an app on my phone and scanning the PSU with it, I can’t take that straightforward route.
The characteristics and condition of the PSU rely on specific apps and system operations. If I still have the handbook or access to the manufacturer’s website, I can grab the necessary PSU information from there. For instance, I can check the power features that Windows 11 supports, but it mainly addresses the laptop’s OS and battery operation, not the PSU itself.
When installing a new GPU on my desktop, it’s essential to ensure it functions correctly. I need to verify that the PSU has the appropriate wattage to power all my components and that all connections are secure.
Now, let me walk you through the steps how to see what power supply i have:
- Unplug the PC’s Power Supply:
- Most people skip this step, but I find using an anti-static wrist strap yields the best results. It grounds me against the computer case, preventing static electricity from damaging motherboard components.
- Hold the desktop and unplug all peripherals, including USB drives, from the wall.
- Remove the side panel for extra workspace, depending on the PC type.
- Examine the PSU connections to the motherboard and other parts.
- Reinstall wires, check for loose parts, and use canned air to remove dust and dirt.
- Take off the screws holding the PSU in place and, once removed, examine it for any issues.
- Verify the Information on the Power Supply:
- Check the sticker on one side of the power supply unit for essential information like manufacturer, maximum output (Watts), efficiency rating, and serial number.
- If replacing, check the manufacturer’s website for a replacement with the same wattage. If upgrading, use calculators like Outer vision or Newegg to determine the appropriate PSU for additional components.
- Updating Your Computer:
- Use bottled air to clear dust and debris if the PC keeps shutting down.
- Consider a new, more powerful PSU if the PC doesn’t turn on after adding a new component, especially a graphics card.
- Connect the computer to an uninterruptible power supply (UPS) to safeguard against power loss, power surges, voltage spikes, and energy noise.
Remember, the 80 Plus certification method indicates the efficiency level of a modern power supply, ensuring consumption doesn’t exceed 20% of its output power. Taking these steps keeps my PC running smoothly and helps me make informed decisions about my power supply.
Checking a PC’s Power Supply | Traditional Method | Recommended Method |
Ease of Inspection | Comparatively challenging, not as straightforward as checking other components like RAM. | Involves using specific apps and system operations, making it less intuitive. |
Data Source | Relies on a select few apps and system operations. The handbook or the manufacturer’s website can also provide information. | The PSU information can be obtained from the handbook, the manufacturer’s website, or specific apps and system operations. |
Power Features Check | Limited information from checking Windows 11 power features, mainly focusing on laptop OS and battery. | Directly checks PSU power features to ensure compatibility with additional components, such as a high-power GPU. |
Installation of New Components | Verification of PSU wattage and proper connections is crucial to avoid functionality issues, especially with a new GPU. | Ensures the PSU has the appropriate wattage to power all components and checks for secure connections, particularly crucial when adding new components. |
How Should I Pick a New Power Supply? 4 Easy Steps!
If, as a result of diagnosing my power supply, I discover that it’s too outdated for my needs, I probably need a new one. If I’m not sure how to pick out a new PSU, here are a few quick, core tips from me:
- Stick with the Same or Smaller Form Factor: Always stick with the same or a smaller form factor compared to the original PSU, as long as I can get the PSU mounted stably in my chassis.
- Consider Capacity Carefully: Going 200-300 Watts in capacity over my maximum estimated wattage will help my PSU run more efficiently.
- Prioritize Efficiency: Stick with 80+ Bronze efficiency PSUs as a minimum requirement (Gold or better recommended).
- Choose Between Modular Options: Semi-Modular PSUs are just as good as Full-Modular PSUs, and cheaper, as long as I don’t have a reason to replace my motherboard power cable.
Conclusion:
The easiest way is for me to check my PSU label—it usually displays the maximum wattage it can provide, reflecting its capacity. Knowing my power supply is crucial for managing my electronic devices. This knowledge empowers me in troubleshooting and planning upgrades. Following these steps equips me to navigate power supply identification intricacies.

FAQs:
Q1. How does an SFX Power Supply work?
An SFX Power Supply is a type of specialised PSU that is much, much smaller than a conventional ATX PSU, but has a similar construction.
That “SF” essentially stands for Small Form Factor. SFX power supplies are primarily intended for use with Micro ATX and Mini ITX motherboard PC systems, since most ATX-oriented cases have space for larger, less costly power supply.
Q2. How can I tell if my power supply is failing?
Look out for symptoms like strange noises, overheating, or intermittent power loss.
Q3. What is a power supply known as BTX?
Balanced Technology Extended, or BTX for short, was the name of a discontinued motherboard form factor that was mostly seen in prebuilt desktop computers manufactured about 2005.
