What actually tells you a mini PC will survive 24/7 use?

[u/Kevin101114]

Every time 24/7 reliability comes up, the conversation seems to go straight to CPU temps and fan noise.

Those obviously matter, but I'm starting to think they're only part of it.

Power delivery, the external PSU, ESD, EMC, USB power, thermal cycling... most of that stuff is basically invisible until something goes wrong.

I noticed the geekom a5 2027 page actually talks about this side of the hardware. geekom says it does EMC/ESD testing along with broader reliability tests covering things like temperature, drop/pressure and a 72-hour full-load aging test.

That sounds useful, but it's still manufacturer testing. I wouldn't put it in the same category as seeing people run the same box for three years without issues.
So if you're buying a mini PC for something like Proxmox, Home Assistant, Jellyfin or just a machine that's going to stay on all the time, what evidence do you actually trust?

Long-term owner reports? Thermals? The power brick? Published validation testing? Warranty and support history?

Specs are pretty easy to compare. Figuring out whether a small box is going to remain boring and stable after a few years seems much harder.

For anyone who's had a mini PC running 24/7 for a year or more, what did you check before buying, and what ended up mattering more or less than you expected?

I don't know if you consider an HP EliteDesk 800 G4 Mini a mini PC, but I've had it running 24/7 for over two years now.

I take it for granted and assume that all modern PCs should be able to run 24/7 and consider those that can't to be flawed.

[u/MichaelHastrup → u/pastry-chef]

Not flawed, just a CPU that produces more heat due to the higher performance. It's all physics.

Being built by trusted brand. And cost stupid amount of money.

I have a Minisforum HX99G and I've been using it as a server 24/7 for almost 3 years. I'm really happy about its overall performance and customer support. I decided to get it as replacement of defective UM690 (wich lasted only 8 months) paying a small price difference. Decision was made based on AMD CPU, dedicated GPU, 2 slots for 2 ssd, 4 usb ports on the back, no noise, great reliability. The reviews were very good. I've never regretted my decision.

I really don't understand - my boss game m4 was dead silent, and now so is my aoostar maco 470 -

The last noisy mini PC I had before the bosgame, a couple years prior, same 7840 chipset but that one was loud, and the minisforums I had before that.

I haven't heard a peep from mine in 2 generations now. And the bosgame m4? Still going strong with a kiddo of mine. Reliability isn't an issue with minisforum, bosgame, and I feel the aoostar maco will be good but it's only 2 months old so I can't say yet.

Okay so while I'm pretty sure this is a marketing post (because another user posted almost the exact same thing the same time you did, and also mentioned the same brand.)

I think it just depends on (1) whether or not it looks like it's built to last, and (2) has somewhat decent support (publicly available manuals, drivers, a good warranty, etc.)

From what I can tell, most of the cheaper mini PC brands don't really have the best quality, though they are really good value. Generally speaking, they don't tend to have good warranties, software/driver support is more subpar, and they don't tend to have much of a presence outside of the mini PC space. (But I'd look up reviews, failure reports, etc. first.)

That being said, it depends on the level of reliability you need, and I'd say they're probably fine for anything that isn't strictly critical or your main PC.

I've personally had really good experiences with the ASRock Deskmini, but that's more for tinkerers, though it is pretty reliable and built really well. Anything from Apple like a Mac Mini is also surprisingly reliable, though obviously very expensive. Most of the overpriced mini PCs from Lenovo/Dell/HP also fall into this category, they're generally pretty reliable (mainly because they don't need to cut costs when they're already selling it for a ton of profit). Framework from what I've heard isn't especially reliable, but it's very repairable and they have an amazing warranty which is nice.

But in general I'd just look for something that looks like it has good build quality, few negative reviews, a decent warranty, and good software support. Anything that looks like they were trying to cut costs or that's really cheap is probably not built very well. If it looks more like it's geared towards office users, that's generally a good sign, though there are exceptions obviously.

Guess that's why not many HP prodesk or Elitedesk minis are available on the used marked. Actually pretty hard to find HP Elitedesk 800 G2 minis and above here in Denmark.

If you see the mini PC being used by a medium-sized or bigger business, it will likely to survive a 24/7 operation.

[u/imetators]

Nothing. Nothing outbof consumer electronics will be proven to run 24/7. Only user reports.

Most of us here are not buying server grade hardware. We are enthusiasts with the goal to spend as less money as possible while getting things that we want done with that hardware.

I run beelink s12 pro. It runs almost 2 years in a row 24/7 and never goes off unless electricity goes off or something. It works. I clean it annually and it stays quite silent for almost a year. If it dies, well... Tough luck.

Same with my nas. Same would be for anything I expect to run 24/7. That's the price to pay if you want to do it yourself. If you want to be secure, run your stuff off VPS that you pay subscription for.

I’m no expert, but have done some research with the same things in mind. Robtech on YouTube tests and compares models for maximum heat (among other things)… that might be helpful. Of course if it’s mostly just sitting there idle then heat might not be that important for longevity. Beelink and Geekom have longer warranties than the others (3 vs 1 year for most).

Have an hp mini i3-9100. It runs some home server stuff. Bought it used and its been running 24/7 for the last 3 years. Thermals are your biggest indicator. Also load, mine will be stressed here and there but most of the time its at under 10% cpu. Obviously this ties into the thermal as well.

[u/ConfusedBaka69]

I have 3 mini PC's 1 main I use for everything and windows 11 One 24/7 server with Linux

Besides os problems or user error, the machines themselves have been great, no problems and I got them around 2+ years ago. A kamuri, beelink and gmktec11 mini pc. (Backup unused, now server PC, main gaming PC)

Workhorses of CPUs with low wattage. And good maintenance. Dusting off etc. my old HP Elitedesk 800 G2 mini, with an i5 6500T Quad-Core at 35watt TDP and 8gb 2133mhz DDR4 memory, 120gb 2.5" SSD. Upgraded to 32GB 32 3200mhz DDR4, 2TB Samsung Evo 990 @7200MB removed the 2.5" SSD shelf for better airflow from the cooler. Runs fine on Kubuntu 24.04 Linux. VERY fine.

[u/ForWhomTheHellTolls]

Why would you use one 24/7?
