How to Check Power Supply Wattage

When you buy a power supply, the first thing that should come with it is its specifications. This example shows how many Watts (w) and Amps (amps). 

Other essential details on this label, such as input voltage range from 100-240V or one 12V rail for Graphic Cards!

To avoid an unstable computer system, you must know the wattage requirements for any device added or upgraded on your current electrical circuit. 

Adding too many devices with higher than expected power draw can lead to inefficiency and potential damage from overheating components within said equipment.

Without Removing The Power Supply, You Can Check The Wattage.

  1. Ensure to unplug your computer from any electrical source and press the power button for 10 seconds before proceeding. 
  2. Remove thumbscrews holding on the rear face of the case located at sides, then pull side panels back with light force to remove it quickly out of place once unlocked!
  3. Locate where you will find a power supply within this area, which should be near the top middle or bottom corner depending on where yours ends up laying inside its enclosure; remember these positions so we can come back here again later down.
  4. A computer’s power supply unit (PSU) is an integral part of the system, providing electricity for all components. Without this vital component functioning properly, you may end up with a dead laptop or desktop PC
  5. Make sure to check your PSU side case panel and tighten down any thumbscrews securely before moving onto step two: Replacing Internal Parts in Case Before Going Offline.
  6. Reconnecting your computer to an electric source is plugging it back into any previously disconnected outlets.

If The Label On Your Power Supply Is Covered, You Can Check The Wattage By Following These Steps.

  1. If you cannot readily see the power supply’s rating label due to its placement on an inward-facing side
  2. Remove the detachable cord that runs from your computer and find four mounting screws. These are found in similar places as before: two each at either end of this cable connection point plus one central top screw between them all.
  3. Your needs are removed so they can be set aside safely without losing any during the disassembly process.
  4. When you have removed all your components from the case, use a light force to slide forward and outward. 
  5. Make sure not to pull or fast as it may cause damage! 
  6. Check every side for specifications labels with wattage ratings explained regarding power supplies (which should be labeled). 
  7. Finally, plug everything together according to what the label says!

What If The Power Supply Tag Isn’t Visible?

If a computer’s power supply can’t find a sticker on the outside,  it has none and instead appears as “power” in large letters across its surface.

Some other identification may be available for inspection, such as side markings near where plugs would go into slots on either end when removed from their housing unit (the front).

A quick internet search will help locate this information but always remember: only purchase new products with these stickers!

Removing the power supply from your computer may seem like a difficult task, but it can be done by following these simple steps. 

If you are unable to find any stickers with ratings on them, we recommend purchasing a new one and making sure that what comes out of this device is safe for use in all three voltage levels (Voltage). 

Be careful when removing old ones, or else there could easily be short- Circuits that will damage various parts within every machine!

Conclusion 

When it comes to power supplies, there is a lot of misinformation. For example, you can’t use a high wattage on a low voltage system or vice versa. 

The best way to check the wattage you need for your device is by looking at its input and output specifications, which will tell you what kind of current (amps) and voltage it needs. 

If you’re still unsure whether your power supply has enough amps/wattage, contact us! We’ll help figure out how many watts are required for your particular application so that we provide the right product every time.
