Works good for gaming – average 100 fps on cpu based games and the fan does get a bit loud when playing intense games but other than that its super quiet and the cpu temperature stays at 50-52 degrees celsius. I haven’t had any problems so fa
The performance of these Ryzen chips is very good. There is nothing in day to day use which would indicate that this is a ‘laptop part’.
The UM790 is surprisingly quiet, coming from an Asus PN50, the latter is much louder. So very happy with acoustics.
I don’t game with this PC, so can’t comment on the performance there.
As many have complained about, the rubber feet which cover the screw holes are stuck on and removing them kills the sticky tape, so they don’t really stay attached anymore. Minor, but bad design.
The PSU seems to be a new model, it is much more compact that the unit which reviewers have previously displayed.
Couldn’t find a way to upload a certificate to the bios, so booting some Linux/grub OS iso requires switching off secure boot, then switching it back on after OS install.
Overall pleased and would recommend. Watch out for occasional discount coupons.
I ordered the HX77G as a replacement for my previous mini-PC that had started to get on my nerves. The old PC would, even just sitting on the Windows desktop, kick up the fans and due to it’s smaller size (about half the HX77G) the fan noise was quite high pitched. I found the HX77G via internet searches and it was said to be pretty quiet.
And that it certainly is. Sitting on the desktop, or even running a benchmark app like Cinebench, the machine is quiet from where I’m sitting (~1.5m from the computer). If I go up to it, I can hear the fans, but even then the noise is a dull, very low frequency hum that easily gets lost in the ambient noice of the environment. Even during some light gaming (Airport CEO, Dyson Sphere Program, Timberborn) the fans stayed very quiet and only came on loudly (you can adjust the temperature when they kick in 100% in the BIOS) at the most hectic times.
Very happy with this machine, I think it will serve me quietly for years to come and spare my nerves.
The inclusion of windows 11 is a bit of a let down (because I can’t stand windows 11) it might have been better to include windows 10 as you have the option to upgrade for free if you really really want it.
I have had a few software crashes in things like development software and virtual box that don’t bode particularly well, but with PC’s you can never quite be sure where things are messing up. For all I know this is just a windows 11 thing. Unless I see a smoking gun I’m not going to point fingers at the hardware.
I did try to get support from minis forum regarding memory upgrades. I was VERY disappointed. They respond quickly enough, just don’t expect knowledgeable responses. That said I get very irate with Dell support so this might not mean anything
The vertically mounted computer is almost silent, except when the fan racks up for cpu-intensive processing, when it throws out a surprising amount of hot air. This indicates that the relatively “state of the art” liquid metal cooling does facilitate excellent heat transfer. Video processing is as fast as one would expect of an 8 core Ryzen 9 chip. The integral graphic processor in the chip works fine with my single 4K monitor and external usb3 blue ray disc drive / recorder. This is a fast machine. What is not fast is the tedious business of reloading software onto windows, a problem of Microsoft not the machine.
Value for money, particularly if you get a good voucher deal, is excellent. I have no experience using the machine for gaming nor have I needed to contact the seller, so I have not rated those items.
Perhaps the best recommendation is that I was sufficiently impressed with the machine that a few weeks later I bought one for my wife. I would have preferred to buy her a more “goof-proof” MiniMac with M1 chip, not that much more expensive. However she is addicted to a particular legacy piece of Microsoft software which, to my surprise, still runs fine on Windows 11.
I rarely write Amazon reviews and it is early days yet, but two happy users of the Minisforum Ryzen 5900HX MiniPC here!
