Amazing PSU
I was a bit hesitant about buying a power supply unit (PSU) from Montech; it's not the most-known brand for PSUs. However, after using and testing it in various scenarios with my 5070Ti, I can say that it's an excellent PSU. It performs well, is almost silent and the cables are long enough and tidy for my build. They also look great inside my Havn 420 case. In terms of value for money, this PSU is excellent and comes with all the cables needed for a high-end build.

Well built, quiet, fully modular, PCIe 5.1 & 12V-2x6 support, great price for a 850W unit
This “MONTECH Century II - 850W High-End ATX Gaming Power Supply - 80 Plus Gold & Cybenetics Platinum - Fully Modular - ATX 3.1 & PCIe 5.1 Ready with 12V-2x6 Cable - 10 Years Warranty” checked all the boxes for me! I am building a gaming PC with a mATX motherboard in the smallest mATX case I can find. I should have used a SFX (small form-factor) PSU but most of them (in this wattage that I needed) are more expensive than I am willing to pay. Then I found THIS one, even though it is NOT SFX (this is actually a full sized ATX PSU), due to the fact that it is fully modular (I only need to install the cables I needed to use), and also it has 12V-2x6 to support my GeForce RTX 4070 Ti, I am still able to fit this into the case nicely. For a 850W, 80 plus gold & cybernetics platinum, with 10 years warranty unit, the price ($90) is great. Even at full blown operation, it is still running cool and quiet. It is very well built, the enclosure is nice and pretty, and all the cables seem to be of good quality. Thank you for reading this review, I hope that this review & the pictures are helpful to you in support of your purchase decision.

Excellent upgrade to feed a hungry GPU
GPUs are hungry. I wanted a new 9070xt to go with my 5800x3d. My old 600w gold PSU wasn't going to cut it. I did some research and saw that this one had great internals and was really good value for the money. The install was easy, I had everything I needed, the modularity was solid, and it works very well. I'm even a fan of the eco mode, which surprised me. Nice and quiet.

Great power supply so far
It's powering my system perfectly. Not a long term review, but it works. It's cybernetics platinum rated, and it's an A tier power supply. It was packaged well, and has all of the cables you'd expect it to. I like that it's pcie 5.1, even if my 7800XT doesn't use a 12V2x6 cable it has one, in case I upgrade. Installed easy, no issues. The cables are all black, pretty neutral and go with anything. You can't see it in my case, but I do think the design is pretty nice too.

Terrible
Pc keeps shutting off mid game. I replaced the psu with one by Msi and the problem stopped…additionally the psu fan would make a weird noise at random times (including the first start)

Pretty nice PSU. Ngl.
So far, really quiet, gets the job done. connectors fit nice and snug, even better than my old ones actually. comes with the velcro things for cable management. Has an eco friendly mode switch, which is awesome for power saving. Sits in my pc really well. Power is very stable, and consistent. No RBG, but not a deal breaker.

Great bang for buck PSU.
Works flawlessly, and got it pretty cheap compared to everything else. Cables feel lower quality than the standard, however, and get damaged easily from scraping against the case.

Top notch quality PSU for the price!
Montech is a brand I've grown to trust highly, and this PSU is no exception. This first caught my attention because of the excellent price. I then researched and found it also got exceptional marks for performance/durability on the Cultists PSU tier list with an A rating which is something I always verify before committing to buying a PSU. It's extremely quiet, connects easily. The black cables make everything look sleek. The only thing I would like to see improved is for the PCIe cables to be another inch or two longer to allow cable runs for different paths in a case a little easier. That's minor though, and it didn't stop anything from working as intended. Top notch quality PSU for the price!
