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

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.

Fantastic power supply. Runs perfectly, new build runs awesome. Installation was the only downside, there is almost no spacing for the ports on the power supply, so some cables are tight to put in with them right next to each other. This, however, is also kind of a plus, because the build looks much cleaner with the cables tightly together on the PSU side. The value proposition on this thing is amazing, the price was great and the quality is top notch. Also, in SPL's PSU Tier List, which extensively tests power supplies for their quality, this PSU is rated A-. That means, it's vetted as a high quality PSU. Summarized, the only downside is a nice design because when everything is said and done things are neat and tidy, the PSU runs whisper quiet, and all of my devices are running great. Montech is a newer company to me but I'm totally pleased and would buy another PSU from them anytime.

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.

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.

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.

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.

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.

I purchased this MONTECH Century II 850W in October 2025. It looked great out of the box and worked fine until this morning. About 8 hours ago, my PC suddenly shut down and refused to turn back on. I went through the full troubleshooting checklist—paperclip test, reseating cables, different outlets—and this unit is completely dead. No fan spin, no sound, no power at all. For a unit that looks brand new, it’s a paperweight. Do not buy this if you expect reliability

Best PSU at this price. Unfortunately not available in all black but it doesn't really matter much.

excellent

Got this one at sale for 63USD. a steal for a A tier PSU with full Japanese capacitors, 10y warranty, silent fan. I rcm this PSU especially at this sale price. you won't have any better option at this price point.

思ってる以上に静かでケーブル取り付けも簡単でした。色合いに文句がなければおすすめです
