I recently cleaned out my PC and unplugged several cords, but now I can't remember where everything goes. I bought this custom-built computer from someone and unfortunately can't contact them for help. The motherboard is a Gigabyte B450M DS3H and I have an RX 570 GPU. I'm not very knowledgeable about PCs, so any guidance on how to get it powered back on would be greatly appreciated!

It sounds like you're facing a classic power connection mix-up. First off, you need to connect the major cables properly: the large 24-pin connector provides main power, there's typically an 8-pin (or 4+4) connector for the CPU, and then you'll need to connect the appropriate cable for your GPU. Each of these connectors only fits one way, so don’t stress too much about forcing them in. Good luck getting it all back together!
Hey! One important tip is to double-check the orientation of your connectors. For instance, the power switch can actually be connected either way as long as it's on the correct pins. Also, make sure to keep track of the power LED and HDD LED connections—they can be a bit tricky but won't damage anything if mixed up. Lastly, don’t forget about the USB connectors; they should match up with the right ports!
A solid tip for future rebuilds: take pictures or videos as you disconnect everything. It'll save you lots of headaches later! As for your current situation, I recommend watching a guide video on front panel connectors. It should clarify where all those small wires go. I've included a helpful link to one I found: [Connector Tutorial](https://youtu.be/nBJJj3FB2P8). Good luck!
