How Can I Find Out the Wattage of My PSU Without Opening My PC?

You can't really find out the wattage without opening it, especially if you're hoping for more detailed info about the unit's quality or performance. There are some tools like HWiNFO64 that can help monitor your system's power usage, but they won't show the PSU's wattage. If you have good reason to not open it up, maybe consider investing in a Kill-A-Watt meter to monitor total usage instead.

Check the back of your PSU; sometimes there's a label there. If you can't see it, the only other option is to open your PC. There's generally not much to worry about – it's really just a panel that comes off!

Honestly, if you're looking to upgrade something, it's probably best just to pop open the side panel and take a quick peek at the label on your PSU. It won't blow up just from looking! Most cases are pretty easy to open, and there's usually just a couple of screws holding the side on.

If you built your PC yourself, you might want to check the receipt from when you purchased your PSU. For prebuilt systems, checking the specifications might help if the wattage is listed there. Unfortunately, PSUs don't typically provide wattage info through software, so you might have to open up your case to find out for sure.
