I just built a new PC using a Ryzen 7 5800X, an MSI MAG A520M Vector Wifi motherboard, a GTX 1050 Ti graphics card, and a 750W power supply unit. I went to power it on for the first time, but it shows no signs of life—no lights, no fan movement, nothing. I've checked all the connections, and everything seems to be in place. I really need some help figuring this out!

What's the purpose of this build? Are any components used? Knowing that can really help diagnose if there's a problem with a specific part.
Make sure the wall outlet you're using actually has power. You could try plugging in something like a phone charger to see if that works. Just to rule out the outlet as an issue!
Just a tip: sometimes the headers connecting your case to the motherboard aren't properly plugged in. It's good to refer to your motherboard's instruction manual on how to connect those correctly.
If you have an older PC around, you could test your PSU with that. It helps confirm if the PSU is functional. And if all goes well, it might be worth checking how your case headers are connected to the motherboard; you might need to consult the manual for that.
First things first, double-check that the switch on your power supply unit (PSU) is set to the 'on' position. It sounds simple, but it’s a common oversight when setting up for the first time!
