Handles high specs with good efficiency. Reliable cables.
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.

Works perfectly
Cable management:Packaged very good. Modular so makes cable management a breeze and everything was good quality. Works perfectly for my i914900k paired with a 4070ti super

Great for the price!
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.

Great power supply
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

Quiet and ready for those next gen GPUs!
The NZXT C850 Gold ATX 3.1 is a fantastic power supply—super quiet with zero fan noise under light loads, and fully modular for clean cable management. It comes with a 12V-2x6 cable for RTX 40/50 series GPUs, making it future-ready. Build quality feels premium, and installation was smooth. No coil whine, great performance—an excellent choice for high-end builds!

Solid Performance, but a bit overpriced
Powerful, quiet, and reliable. Handles high loads with no problem. Just think you can find equal value for less

An amazing gold rated power supply
I picked up this PSU when it was on sale at the recommendation of LTT Labs because it reviewed very highly. Out of an abdunce of caution, I ran a battery of stress tests and this power supply didn't skip a beat. I have no doubt it'll perform at its best for many years to come.
