    • Amazing PSU
Style: 1050W
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. ... show more

    • Excellent Power Supply With Plenty of Headroom
Style: 1050W
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. ... show more

    • Great BANG for your buck.
Style: 1050W
Really really awesome power supply for the money, purchases mine on sale for about $90. For what it is and what you get it's great, quiet, no coil whine and no hiccups in the 3 months I've had it so far. It's a future proof with a 12VHPWR connector. Built really solid, even the packaging is pretty premium for what you get. Can't ask for more from a power supply. ... show more

FLAT CABLES! That's all you need to know. I've always ordered customs but I needed to trim my budget. These flat cables are super nice and flexible. The unit is built like a tank. Seriously, my OC i5-12600k and Rtx 5080 plus 8 fans (6 arbg) are running like Kenyans. My days of over paying for a Corsair PSU is over. ... show more

    • Excellent upgrade to feed a hungry GPU
Style: 1050W
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. ... show more

    • Almost Perfect, but Fan Shroud is Concerning
Style: 1050W
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 metal shroud introduced by the case, plus any case dust filter will drastically diminish the amount of air this PSU can pull if your fan ever needs to spin up. ... show more

    • Perfect buy and Price for a 1050 Watt PSU!
Style: 1050W
No complaints, it's a powerhouse for my PC. It matches perfectly with my Montech setup. Ease to install, works perfectly with The Montech 95 Pro case. Noise level is great, all PC's and laptops make noise that you can hear unless it is specifically designed so that you don't, 8/10 for great noise level. The vent design is pretty cool, and the color blends in well with all the internal parts, which consists of Grey, Black and white. The price is perfect for a 1050 Watt, this price is very hard to find anywhere else on the market. 10/10 so far ... show more

    • With great power, comes an even better price
Style: 1050W
Works great, cables are nice and durable, only downside for me is that one of my cpu cables had a bad latch on the psu side which I assume was a lemon, but otherwise the entire set is perfect.
