I've noticed a smell coming from the back of my PC when I boot it up. It's not an unpleasant smell, more like new electronics, and it fades away within seconds. I suspect it might be coming from either the power supply unit (PSU) or the exhaust fan. I built my PC about three weeks ago, and this smell only occurs on startup; there's no smell when I'm playing graphic-intensive games or using other applications. Is this something I should be concerned about?

It’s pretty common to notice a smell like that right after you first boot up a new PC. Sometimes it’s just residual manufacturing substances burning off. If it fades quickly and isn't accompanied by any strange noises, you’re likely fine. Just keep an eye on it in case it changes.
I had a similar experience with my new build. The first few times I booted up, it smelled a bit like plastic, but it went away after a while. I think it's just everything warming up, as long as nothing's overheating or getting stuck.
If your PSU is 1000W like you mentioned, it could be the fan only kicking in on startup or maybe even some dust burning off that settled since the last power-up. You might want to check if there's a BIOS setting that makes the fans blow dust out at start.
Sounds like a typical occurrence, especially with new electronics. Just make sure no cables are caught in the vents or anything that might cause overheating. If it keeps happening over a longer duration, you might want to take a closer look.
