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.

A phenomenal PSU rated A+ on the PSU tier list. Works perfectly as expected and the price is really good. 10 year warranty is exceptional.

This is compatible with the Powercolor RX 9070xt Red Devil which requires three 8 pin PCIE cables. The c1000 PSU has five 8 pin PCIE cables. In my rig its 2 for the motherboard, 3 for the red devil graphics card. This is rated A tier on the Cultist PSU tier list, its a quality PSU. Be aware, this has only one 12v-2x6 cable. Lots of other power supplies have two 12v-2x6 cables but then only four 8 pins so know what you need.

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 product & great price point. Feeds my power hungry RTX3090 and Ryzen 7 9800X3D without any issues. I've come to trust NZXT in the market and this definitly does not disappoint. If you need more power and you don't want to break the bank, this is it.

I have had zero issues with this PSU powering a 9070xt and a 7900x. It looks super nice and comes with braided white cables that feel premium.
