Powerful, Quiet, and Built Like a Tank
The NZXT C1200 Gold ATX 3.1 power supply has been an absolute game-changer for my PC build. Build Quality: From the moment you take it out of the box, it feels premium. The matte black finish, clean design, and fully modular cables make it look as good as it performs. Everything about it screams durability. Performance: With 1200W of 80+ Gold-certified efficiency, it delivers stable, reliable power even under heavy loads. I’m running a high-end GPU and multiple NVMe drives, and this PSU doesn’t even flinch. Voltage stability is rock-solid, and the ATX 3.1 support means it’s ready for the latest GPUs and beyond. Noise Levels: The low-noise fan profile is fantastic. Even when gaming or rendering, the PSU stays whisper-quiet—most of the time, I forget it’s even on. Modularity & Cable Management: Being fully modular, it only uses the cables I need, which keeps my case airflow clean and organized. The included sleeved cables are high quality and easy to work with. Bottom Line: If you’re looking for a future-proof, ultra-reliable, and quiet PSU that can handle anything you throw at it, the NZXT C1200 Gold ATX 3.1 is worth every cent. Perfect for enthusiasts and high-performance builds.

Great Power Supply, No Issues
Very quiet, cable management is easy, plug ‘n’ play, compatible with my 9070 XT Reaper and Asus B650E-E Tuf Gaming Wi-Fi AMD AM5 ATX motherboard. The cables feel very nice and durable. The best part about it is not having to worry about having extra cables you don’t need. Definitely invest in a power supply in this range. It’s a very normal sized power supply and will fit fine is a regular build.

Amazing PSU From NZXT
I was a bit hesitant about buying a power supply unit (PSU) from NZXT; it's not the most-known brand for PSUs and some reviews on Amazon were not the best. However, after using and testing it in various scenarios with my RX 9070 XT, 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 white case. In terms of value for money, this PSU is excellent and comes with all the cables needed for a high-end build.

Great power supply overall.
Had this for a few months, it is a great power supply overall. It remains close to silent even at 75% load, which is the ideal situation. It is also very efficient at low loads, limiting idle/off current waste, probably due to . Build quality is great with excellent cable management and outlets.

An A+ power supply, the heart of any build, with a horrible black power cable.
A great power supply, it feels very high quality, super heavy, the cables are super thick and sturdy, although they are quite stiff to handle during assembly. Aside from that, it feels premium, the packaging is top-notch, which is appreciated. Extremely quiet, I can now feel confident that my entire build is safe with an A+ rating power supply. It seems that NZXT is proving to be a brand that can compete with high-quality products. My only complaint is, if I'm buying everything in white, who was the genius who thought of including a black power cable in the box?

Real quiet PSU.
Needed a replacement power supply for my NAS, and this happened to be on sail at the time. I haven't had any issues with it, and the included cables / cable bag is pretty nice! I honestly had no idea NZXT was doing power supplies. I am sure its a rebrand of something else, but its really nice, and the fan is quiet. Came with more than enough cables for my needs, and I was happy with the price.

Great PSU unit and Bag but...cables not so good
First NZXT PSU I've ever bought is this C1000w Gold. Lets start off by saying the unboxing, look, feel, build quality, and weight of this power supply is very nice. It has a textured look and feel, the silver band with logo is pleasing not intrusive. The purple cable bag is a nice touch, and this C1000w unit should have good performance for years to come. Even with powering my high end setup: Ryzen 9 9950x, RX 9070 XT, 96GB, etc. in an NZXT H6 Flow case. The PSU is really well built with solid internals, has a 10yr warranty, and it's a nice looking unit. It should fit into most cases ATX, mid tower, etc. Coming with all white cables was a plus, so I don't have to buy cable extensions. At least that's what I first thought too but...First off it does come with all white cables, all but one...why would you put a black power cable in with an all white unit. I get it and can over look that, no biggie. Then I get to the PSU cables themselves and....They are so stiff I could barely bend them, and they weren't cold. Trying to bend them makes them feel and sound like they're cracking, not a fan. The flat cables that it comes with aren't too bad, but still stiff and plastic feeling. The 24 pin cable that's sleeved is glued, then covered with 1" heat shrink. The 3 GPU cables and others with sleeves are glued, then covered with .5" heat shrink. The worst part is the sleeves don't even come to the end of the cables, it starts about 2-3" away from the end. The part that's glued and covered will not bend no matter what you do, making it really hard to manage and ugly looking. That's even if you can get them into place without feeling like you just had to force it and you're hoping the motherboard will hold...I couldn't live with that. So I had to buy cable extensions. The PSU unit is awesome, the bag is great, the cables...not so great. Maybe just okay. The unit gets 5 stars, but the cables bring it down to this outcome. I will update this review with it's longevity. NZXT really needs to work on their cables. ~Be prepared for the extra cost of cable extensions, starting around 30 bucks...Cause I Wasn't.

Amo las fuentes de nzxt. Tener en cuenta que los cables al ser mallados es difícil hacer organización de cables pero es muy buena fuente que rinde muy bien y casi no hace ruido y se calienta la que tenía era una de 650 wats mismo modelo y ya tenía 9 años con esa fuente salen muy buenas

Desde que abres la caja se nota la excelente calidad de esta fuente de poder. De las mejor calificadas por Linus Tech Tips. Los cables son gruesos y no tan flexibles, por lo que podrías tener problemas para maniobras en gabinetes pequeños. La instalé en un sistema con el procesador Ryzen 7 9700x y una Nvidia RTX 5070 ti.

Adorei a fonte. Os cabos sleeved são muito lindos e ela possui o conector ATX 3.1 de 600w 12v-2x6 mais recente para placas da série 5000.

Es perfecta, de alto rango obviamente pero cuenta con ciertas características que hacen válida su compra para equipos de alto rendimiento. Perfectamente funcional, no hace nada de ruido y extremadamente eficiente. Hasta el momento no había tenido una fuente de poder de esta calidad y no me arrepiento de su compra.
