    Great PSU for the price

    Very great power supply for the price, especially when it goes on sale for 89 dollars. I haven't had any issues with it, since the month I've had it and installed it into my computer, which is running a 270k plus and a 9070xt. The fans are pretty silent all things considered, but you'll probably hear them a bit when they're running at close to or full rpm. Cable length, they're pretty long so you can definitely use this in a full tower case, I'm using it in a mid tower case and I definitely have extra length still. It's also modular, so I only used the cables and there's quite the variety and

    Amazing for price and performance 5 stars here

    Bought as an upgrade for a ryzen 7 7800x3d and a rx 9070xt. I like how the unit feels hefty and well built. Love the design. Was a steal at the price. I tested it straight out of box and tested with psu tester it turned on right away. It is whisper quiet while running idle. Had to put ear to it to hear fan. Still was very quiet. Highly recommend this and it ranks good on psu tier list.

    Montech wins again

    Went with Montech for two reasons.1. I've ran their Metal Series AIO. I liked it when I purchased it. I loved it after using it! The warranty on it is 6 years. Yes, I know this is for a PSU but, that same awesome warranty period exists on this product too. 10 years. Not many can compete with that.2. The price for their products are insanely competitive to the "other guys". More value for its performance.Those two reasons sold me this time over MSI. Yes, I'm a Micro Star fan. I only run their MB's but, this PSU compared to MSI's equivalent, I would've spent roughly $20 more and would've got 50w

    Excellent Power Supply With Plenty of Headroom

    This MONTECH Century II 1050W power supply has been excellent so far. It’s fully modular, which made the build much cleaner and easier, and it came with all the cables we needed. There is plenty of power for my son’s system, and everything has been running great.We’re using it with a Ryzen 9700X, 32GB of DDR5 6000 memory, and a Radeon RX 9070, and it has handled everything without any issues. It feels like a solid, high-quality power supply with more than enough headroom for a gaming PC.So far, so good. Very happy with it.

    Almost Perfect, but Fan Shroud is Concerning

    The best value-for-money PSU you can buy. 10-Year warranty with superb reviews, fully modular, and 1050W is absurd at this price. I have this PSU in my home-lab with the low-noise fan enabled, and I genuinely never hear this PSU fan turn on. I have never had a single PSU related issue since installing it.The cables are not great quality, but they're cables, and long-enough to work in any modern case. I have this installed in a massive Fractal Design Define R5, and I've got plenty of length. My one concern is the fan shroud design. With how small the cut-outs are for the fan, plus any sort of m

    Pleasantly surprised!

    Never heard of this brand and I know a PSU is not really something to gamble with but I did.. I really can't say much about it, but it's modular making cable management very easy, it is literally silent in my build, perfect size, does not seem to overheat at all and powers a high powered gaming PC that runs for multiple hours a day

    Energy efficient. Running 24/7 at 800W without issue.

    The Montech Century II 1050W PSU has been running very stable 24/7 at 800+ watts since I installed it over a month ago.I hadn't heard of this brand before and there weren't that many reviews about this power supply, but I saw a post about it over on tomshardware.com.I decided to take a gamble and bought this, and I haven't been disappointed.This replaced a Corsair RM650 that I had running 24/7 at 700+ watts (yes, it let me over-draw), but occasional spikes in power draw tripped it and took the system down.The workstation I installed it on runs AI image and video generation (ComfyUI), AI infere

    Sold in European amazon without European compatibility.

    No type F plug included, why bother selling it in Europe if it does not accommodate the European market standards?
