    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 GP

    Good psu, clean aesthetic, good connection options

    Great power supply. Haven't tested it with a power hog gpu like a 5090 or anything, but wanted to ensure the build had room for one in case a hungry gpu gets thrown into the rig. Bought the white model, clean looking, and a good set of wrapped cables to keep things more compact and manageable...Although I'm using sleeved extensions for a cleaner look. Build this rig a bit ago compared to review, price has risen, as such, I probably would lean more towards a few other reputable brands with ATX 3.1 units considering such. But still a great psu.

    I have 2 of these - zero issues.

    I bought one with my 5090 and one for my 3080ti.Both work great with zero issues.I’ve been using them both daily for 7 months with no problems.When I play games with my 5090 I will spend 12 to 14 hours a day gaming, and this power supply has been GOLD so far.I will post back if I have any issues, but I doubt I will have any.

    Shuts Down. Not as stable or reliable as 10year old Dell PSU

    My Specs:AMD Ryzen 5950X 16 core/32 thread CPU64gb DDR4 3600mhz RAMMSI RTX 3090 24gb GPU1TB m.2 NVME for Windows2TB m.2 NVME for gamesI was running on a ten year old Dell 1000w power supply. I use them because they are generally very beefy and reliable. But I wanted to upgrade to something nicer that matched my all white PC. I chose this 1200w so that if I upgrade to a 5000 series RTX card later I would be better prepared. Plus I love having some overhead.I made the swap, the all white PSU and Cables looked great. I started playing games and within one week I got my first shut down. The entire

    10 months later and still no problems thankfully

    10 months later, Sturdy, well built, future proofed. Lotta hate I see online in places like Reddit about it, but so far so good, unlike some of these negative reviews that look like user error, I made sure this thing was perfect out of the box before installing and it's been silent and smooth ever since. For reference my DIY gaming PC setup only draws around 450 watts - 475 watts when gaming, I just got this overkill PSU because I figured why not, it'll protect against power surges easily with this much headroom.

    Nice power supply for the price

    This power supply is a great choice for high powered video cards and high end CPUs, the cabled are fully sleeved and the 16 pin PCIe cable provides even power across all 6 pins
