Yet some power supplies tend to go up in smoke a lot more frequently than the others. You live in US, so I'll give you some familiar examples.
Why do you think Dynex and Rocketfish no longer sell rebranded crap?
We have a local brand similar to Dynex, which sells bottom of the barrel PSUs and PC accessories, and they are famous for being a literal fire hazard. One of my customers used to love these cheap PSUs of theirs for saving a few bucks on their call center PCs, until every single one of them started to die, some with smoke and fireworks. It only took a year for him to figure out that it's actually cheaper to spend $50-60 on Seasonic S12III with 5-year warranty than replace dead PSUs and burnt motherboards every few months.
There's also chinese Gamemax, which is also famous for high defect rate. I have about 150 units at my office just from one retailer (bought for $0.25/ea in mint condition, dead OOB).
Another thing you have to remember, is that just because PSUs is alive after all this time, it's going to work with modern system. Many pre-2000 chieftecs are still alive and kicking, but they are guaranteed to cause stability problems on anyhting newer than Haswell, even if you do a complete recap and cleanup. I get at least one case a week, where an "upgraded" PC has a PSU older than its owner. It kinda works, but ripple is so bad that all you see is BSODs as soon as you give it some load on 12V rail. Most no-name crap is based on those old PSU designs. That's why this Mercury PSU has ridiculously outdated stickers like "SLI-ready" and "Crossfire-ready", even though it's a thing of a past decade and most importantly it only has a single 6+2 pin. I wouldn't trust a PSU that has lies written all over it.
Definitely a LiteOn from Lenovo prebuilt. Real 80+ certification, real spec. More than enough for i3-9100f and GT1030.
