Works as expected - It works like it should, comes with all the cables I needed. I haven't had power outages or anything to really test it's worth, but it was easy to use and has everything I needed

Works Great! - I recently upgraded my PC with an NZXT power supply, and I’ve been genuinely impressed with the experience so far. Installation was straightforward thanks to the fully modular cables, which made cable management much cleaner and easier inside the case. The PSU runs very quietly, even during gaming and heavier workloads, and the system has been extremely stable since the upgrade. I also appreciate the solid build quality and clean design. It feels premium and reliable. Voltage delivery has been consistent, and the included cables were high quality and easy to work with. One of the best parts is the peace of mind from the long warranty and trusted performance. Overall, this NZXT power supply delivers excellent reliability, quiet operation, and great value for a modern gaming or workstation build. I’d definitely recommend it to anyone looking for a dependable PSU upgrade.
