I was a bit hesitant about buying a power supply unit (PSU) from NZXT; it's not the most-known brand for PSUs and some reviews on Amazon were not the best. However, after using and testing it in various scenarios with my RX 9070 XT, I can say that it's an excellent PSU. It performs well, is almost silent and the cables are long enough and tidy for my build. They also look great inside my white case. In terms of value for money, this PSU is excellent and comes with all the cables needed for a high-end build. ... show more

    • Great power supply overall.
Color: Black Size: 850W Gold Style: C Series ATX 3.1
Had this for a few months, it is a great power supply overall. It remains close to silent even at 75% load, which is the ideal situation. It is also very efficient at low loads, limiting idle/off current waste, probably due to . Build quality is great with excellent cable management and outlets.

    • I feel the power!
Color: Black Size: 850W Gold Style: C Series ATX 3.1
This was perfect for my new build. Shipped fast and was used immediately. 850w is perfect for a new AM5 build. Modular wires are all good to go as well. No issues.

    • Bad Azz PSU
Color: Black Size: 850W Gold Style: C Series ATX 3.1
This is a great 850 watt PSU, especially for the price. My Specs: Ryzen 9 9900x with a 360 AIO Gigabyte X870 Gaming Wifi6 Mobo 128GB of DDR5 @ 6000MT/s Sapphire AMD RX7900xt OC Storage: One Gen 5 NVMe, Three Gen 4 NVMe Drives (One NVMe is attached usi6a PCIe to NVMe adapter) My current draw at full GPU, CPU, and RAM load is 690 watts, this PSU doesn't break a sweat. Regular gaming/encoding uses about 300 to 400 watts. This PSU is 100% Worth the Price! Plus it has that crappy Nvidia 12VHPWR Connection. Oh also You can make the PSU fan silent with the push of a button which is a nice inclusion. ... show more

    • Starting to show faults after 6 months....
Color: Black Size: 850W Gold Style: C Series ATX 3.1
The build quality seems nice but after about 6-7 months my PC would just randomly shut down and start up. It wasn't restarting since the PC would briefly fully power down for a split second then boot back up. I could tell since every time it did I would heard a "click" noise which some power supplies do when powering on and it would make that noise... which it doesn't make that noise if I would to simply restart my PC. I would also put my PC to sleep and it would just turn off after some time when it's asleep. Every time it does it I would see a "Kernel-Power" error in event viewer when it boots up from turning off or when I turn it back on from putting it to sleep. I replaced it with a be quiet! power supply and that fixed the issue. ... show more
