    Best bang for your buck

    Bought this because I upgraded to a 5070ti and my factory 650w psu was not gonna cut it. Came with every cable i needed (in cool case too)and the install was extremely simple even if you're not a pc builder. Took maybe 15 minutes to swap it out and since its fully modular, you only hook up the cables you need. Its so convenient. Came with a 12vhpwr cable too so you don't need an adapter for newer gpus. Makes no noise from my experience and had a zero fan button to keep noise down even more. Love it and will highly recommend it for someone whos upgrading to a current gen gpu and needs the power.

    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.

    If you have a mid-high tier setup get this PSU

    I recommend this PSU to anyone who needs a good value, good quality, easy to install PSU. not only is it fully modular, it looks good and has functionality that will keep your build running safer than using a different PSU. If you have an expensive setup DO NOT cheap out on a 80+ Bronze cheap PSU that barely keeps your build safe. If you have a RTX 5070 Ti like me I recommend a 80+ Gold.
