    • Good packaging, cool and quiet.
Color: Black Size: 1000W Gold Style: C Series
No issues in my high end pc build. The packaging is nice, it comes with a neat NZXT branded zipper pouch for all the power cables. Zero rpm mode is a plus, it generally stays cool enough that the fan doesn't need to run, but you can switch it to always on at the click of a button. When the fan is on I don't notice it over the sound of the rest of my pc. Wattage is high enough to handle practically anything for the next few years at least. ... show more

    • Nzxt for the win
Color: Black Size: 850W Gold Style: C Series
Not much to say about a psu. Works as intended, easy setup. Cables are super stiff out of the shaving kit they come in but a little warming softens them up enough to fit them in the build. Comes with way more cables than the average build would need. Quality sheathing and management options. Worth the money for a psu with room to grow. ... show more

    • Quiet and effecient.
Color: Black Size: 1000W Gold Style: C Series
I was troubleshooting PC crashes under load. I had a 600w PS in a system that could hit 450w under load. This over time I suspected degraded the PS.. so I bought a new PS@ 600w and still had the same issue.. I knew it was not the CPU OR MOTHERBOARD.. so I now got THIS PS (NZXT C1000 PSU) and all my troubles are gone. Quality PS with enough extra watts does matter.. This one is Quality and will not let you down. ... show more

    • Good but…
Color: Black Size: 850W Gold Style: C Series
This is my first review. I’m an average pc user. I know how to do things, but I’m not pro at them, so installing this PSU took me 2 days. Honestly it would’ve took me a day at max, but I kept getting stuck on stuff and I took out some plugs I didn’t even need to take out cause it wasn’t connected to the PSU. Anyway onto the PSU. I’m giving it 4 stars for two reasons. The biggest reason is because these braided cables suck! I’m not doubting them being high quality and I’m actually not good at Cable Management, but for my Case (Lian Li Lancool 2 Mesh Performance) these braided cables made things so much harder for me to connect things to the Mobo and a neat fashion because how thick the cables are as well. They’re actually pretty flexible, but I hate these cables for my PC. Other problem I had is probably due to the PSU, but some Cables can just come out easily. It’s really the Mobo Cable. Both sides come out of the PSU and Mobo easily no matter how hard I put pressure to them. My last problem (not sure if it was a problem) was that after 2 days of work, when I finally turned the PC on, the PSU smelled like it was burning. I quickly turned it off and unplugged it after waiting a few secs. Nothing exploded and everything was fine. I ended up doing research and found out new PSUs can smell like burning for a short while due to something called no clean flux. What I did now was connect the PSU to a testing bench after researching for a hour and when I did, I smelled no burning at all anymore. I monitored it for 30 mins, nothing. I finally put it back in my PC and monitored it for another hour and nothing, so all is fine. Best thing I got outta this was the experience. I was able to hook the PSU back up pretty fast. Sorry for the long message. overall the PSU is very high quality and besides the things I said, I would recommend it to you. ... show more

    • Well-built power supply
Color: Black Size: 1000W Gold Style: C Series
The OEM PSU in a Lenovo T730 is not enough for upgrading the GPU even a little bit. Enter this power supply which is a direct fit, but needs to be installed upside down due to the ventilation direction. The cables are modular which is nice, but the main 24 pin is too thick to use the standard cable routing and had to run through the main chamber. All that taken care of, the PSU works well, has the ability to turn off the fan completely when there is low heat generation, and has not caused a shutdown due to power demand exceeding supply. ... show more
