are consumer grade power supplies designed to run 24/7?

are consumer grade power supplies designed to run 24/7? I know many of you run machines at home 24/7 (servers, maybe even desktops) that run on standard consumer grade hardware/PSUs. Is this safe? Is there even a remote risk of fire hazard? I'm curious to know what (if any) anecdotes you all have on this matter.

"Look for power supplies that are built to specifications set forth by Underwriters Laboratories (UL).

Power supplies certified by UL are almost certainly guaranteed not to burn your house down."

"I've run 6 cheap desktop machines 24/7 for years, and I never had any problems.

However, I did lose one machine to a power surge."

Leaving a computer on 24/7 has been considered somewhat normal for at least a decade. I wouldn't worry about it.
