Goat of budget quality PSU's
The goat of budget power supplies. 80+ Gold rating, 850W, modular cables, 0 RPM setting, and 12VHP all for ~$90. Runs perfectly and really I don't have much to say that other people haven't already mentioned. Fan is not aggressive at all, and damn near dead silent with the 0 RPM mode off. Comes with all the cables I'd need. This PSU puts its money where its mouth is. Planning on using it for a commission build as well as some other personal builds I'm thinking about. [Update] I did end up using it for that commission build, turned out amazing, no SATA power cables broke (unlike my EVGA P5), works amazing for a server PSU.

Good value and quality
The PSU IS GREAT! This psu provides great value for money, making budget builds perfect especially for its wattage it supplies power to everything perfectly with no issues whatsoever, it is very quiet and makes 0 noise at all, no coil whine or anything cables were also in perfect condition. Overall great psu i'd highly recommend buying it.

This unit is worth every nickel, since pennies no longer exist
It's got all the power! I'm running i7 14700kf w/ Intel arc b580 on a gigabyte UD board. The dual power plugs for the CPU, dual channel with ability to run ddr5 @ 7200Mhz without issue.

Well built, quiet, fully modular, PCIe 5.1 & 12V-2x6 support, great price for a 850W unit
This โMONTECH 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 Warrantyโ 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.

This PSU is great!
This is probably the best power supply I have ever owned. I bought a 1000W version of this an another website and it has been going strong for a whole year after multiple power outages. It runs cool and runs quiet, 2 important things as a game and content creator. The only negative is the unit is a bit ugly if aesthetics matter to you. It's an odd grey color that I added to an all white PC build, but that is just a nit-pick. This thing rocks! Currently powering a Ryzen 5 7600X and a RTX 3080ti.

Good customer support
PSU works great, runs quiet, I like the smart mode. Unfortunately the fan bearing went out after 6 months and made a terrible rattling noise. Customer support was quick to send a replacement.

Budget to Ultra High End? Works For All!
This is the absolute meta for PSUs. Why spend $150-$200 on PSUs when you cant get over 1000w for slightly above $100? A- on the PSU tier list, Cybernetics Platinum, 80 Plus gold rated. YOU CANT GO WRONG. Installs just like any other power supply so ease of use is the same, its entirely modular so you plug in all the cables into the back yourself which is great for cable management. Its actually smaller than usual for PSUs and its way lighter than you might think. Other people have complained about coil whine but ive never heard any noises coming from mine ever. Ive made 2 different PCs with this PSU and no issues. I will always recommend anybody on any budget go for this PSU.

Didn't work, customer service refused to help
PROBLEMS ALL AROUND Simply didnt work right after 1 week. PC wouldn't turn on. I ended up buying a Corsair RM850x instead, and got much better results. The reason for having to buy the Corsair, was the terrible customer service. All I asked for was a replacement sent to me and they absolutely refused to. I wanted the replacement to sent the defective unit back into the replacements box. That way I can get my power supply unit quicker than having to send the defective one in, and then wait to get a refund, then I can get a new unit. I use this pc for work, so time is important. I still havent heard back from them about other ways to work around this problem. Because of this, I ended up having to buy a Corsair power supply (one i mentioned earlier). The Corsair was a little more expensive at $130, but already simply that much better and well worth the additional 40 dollars to have a 10 year warranty, and not having to deal with this customer service if something were to fail. Corsairs power cords are top notch as well, extremely easy to move cords around. Super displeased overall, mainly with the customer support. I understand lemons can happen. I wouldnt be writing this review if the customer support was at least trying to make things right.
