    • Handles high specs with good efficiency. Reliable cables.
Color: Black Size: 1000W Gold Style: C Series ATX 3.1
This is a very efficient and quiet power supply. It can handle an Nvidia 5090 and AMD 9950x. A silent mode toggle keeps the rpm's low on its fan so when idling it's essentially silent and stops spinning. High quality cables. No melting issue with the included cable for my 5090.

Color: Black Size: 1200W Gold Style: C Series ATX 3.1
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. ... show more

    • Great power supply
Color: Black Size: 1200W Gold Style: C Series ATX 3.0
No problems with performance and functionality I can really tell any noise it's very quiet I have not used the power save mode because my PC is a very power hungry PC The size is exactly how it says so it fit in my case perfectly

I needed this when I upgraded my processor and motherboard. My PC case is tight on space and the modular ability of this power supply is super useful. I saved all the extra cords in the box if I need them down the line. The power supply has enough chords and plugs to do everything I need to. The circulation and noise level is no different than any other power supply. ... show more

Color: Black Size: 1200W Gold Style: C Series ATX 3.1
Very good PSU. It comes with all the needed cables to connect to high end PCs. I've used it with an MSI z890 Carbon Wifi, with a Core Ultra 7 265K, RTX5070Ti.
