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 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.

Super nice and powerful. Working flawlessly.

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.

Got this for my pc and works 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.

I went through 3 other power supplies of a different brand (cough, MSI, cough) and they all had horrible, annoying coil whine. I kept returning them and getting a replacement, thinking I got unlucky. I even tried a slightly different models, all 3 had unbearably annoying coil whine. This Montech Century II is blissfully silent. No coil whine, no fan noise, not a peep out of this thing. It is such a relief to have found an actual QUIET power supply. Not to mention highly rated by experts, all the features you would want, plenty of power, and inexpensive compared to the bigger brands. My only small complaint is that the fit and finish of the cables are pretty basic. They are flat, which is nice, but are just a basic, shiny black plastic. If it keeps cost down, so be it. I'd rather have something that works well and is quiet. This is the one!

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

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.

Very good power supply, had it for a while and it’s been doing me well with no issues

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

今回、Radeon9070XTで組んだ為、850wでGoldの製品を探して居ました。グラボにお金が掛かり過ぎて（笑）安価で良い製品を探していた所、この電源を発見。日本人のレビューが無いため初め心配でしたが、星４以上のレビューが多く、また電源の作りや出力特性も良いようなので購入。少しコードは硬いですが、問題ないです。

Great quality well packed by scan and the manufacturer so arrived in perfect condition. All the cables are labeled nicely. No issues with installation, just a shame my case mostly hides the nice design 😀
