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.

Professional at budget price
Works better then Corsair and has more power per dollar vs the competition. Great ratings and inside components easy to use wires are flexible

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.

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.

Thought I bought a quality product for cheap, but it nearly fried $3000 worth of PC components.
Cheaply made. I purchased this power supply based on the reviews I saw from various websites. They clearly only tested the functionality, and not the durability. I bought mine on November 9th, but didn't have all the components to build my PC until Christmas. So, my PC has been up and running for about 3 weeks. My PC randomly rebooted the other day, and being the tech nerd that I am, I had to find out why. I couldn't find anything. I took the entire PC apart and re-socketed each component. Still couldn't find what the problem is...until I used a flashlight and saw a glimmer from the PSU. Turns out, the modular PSU to CPU power cable had started to melt!!!! This melting issue could've easily friend my motherboard, video card, PCI-E adapter cards and my RAM, all of which cost about $3000. I'm only writing this review because I emailed their support team, and they haven't replied. Edit: the manufacturer hasn't replied to my warranty request in 2 weeks. Just straight up ignoring me. Fortunately, Amazon sent me another one, but from my experience, you cannot expect the manufacturer to honor their warranty. 2 weeks with no reply and the warranty request was submitted through the manufacturers website.

Great PSU , Low noise , efficient , i also really like the look too even if i wont be able to see it in the case. had to replace my old EVGA PSU due to space constraints. Just an awesome budget PSU

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.

Awesome
Shipping was questionable. It could’ve stood to be inside of the box instead of the plastic Amazon bag. The box has a small hole in it from shipping. Other than that. The part itself was untouched. The cables were untouched and everything worked as it should. I install it in my rig. It was straightforward easy to do. This PSU is A class lots of room for future proof

Only ordered yesterday afternoon, and wasn't expecting it till Monday but arrived first thing this morning. For the price I'm more than happy with the PSU so far, high build quality for budget friendly money. It's got its own smart fan to keep it cool, which is quiet so far. And completely modular, and quick to install, less than an hour to swap over. Plus 10 year warranty, would definitely recommend.

Happy with it, does the job although one of the pins for the MOtherboard cable wasn’t seated correctly, managed to force it in and haven’t had problems. I hope the company get rid of DPD delivering their items as it’s been a nightmare! I usually stay clear of DPD and EVRI but I risked it for the outstanding price
