My brother is set to get an RTX 5090 for his work, and I'm a bit concerned. While he's a talented guy focused on film editing and some light gaming, he has a habit of leaving his PC running for days, even weeks, without turning it off. I want to know what best practices he can follow to save energy and reduce the risk of overheating or equipment failure. Besides undervolting and ensuring cables are securely connected, should he consider additional tools like the Thermal Grizzly WireView Pro? Are there any other recommendations?

Buying a system with a solid PSU like the Seasonic Prime TX-1600 is a smart move. It's crucial to have a power supply that loads balance well, but in essence, if he just uses it for basic tasks, he shouldn’t face serious issues.
Honestly, leaving it on all the time is pretty common. If he's not pushing it with heavy loads like rendering or gaming, it shouldn’t be an issue. Just make sure there’s good airflow in the case to keep everything cool.
You don’t need to worry too much about it melting if it's just idling. People use powerful GPUs like the 5090 for extended periods without problems. If he's idle for weeks, the power draw is minimal. Just make sure he has a good quality PSU.
I have an RTX 5090, and my workstation stays on 24/7. One key thing to do is to set a power limit on the card; this can help prevent overheating. Also, make sure to have a very reliable PSU, as that matters a lot for stability and safety.
If he's worried about cable issues, consider getting thicker cables or a better connector designed to keep things cooler. Also, ensure the case is spacious so cables aren't kinked. Adding a smoke detector wouldn’t hurt either!
