## Customer Reviews

### ⭐⭐⭐⭐⭐ Quiet and powerful when needed
*by D***L on March 21, 2016*

I originally bought this because of the good reviews and my previous experience with Corsair PC components. I can say, I'm not disappointed. The fully modular design allows just the cables I need to be plugged in, reducing potential disruptions in airflow caused by unnecessary cable clutter. The USB port on the PSU allows the device to plug into an internal USB 2.0 header and communicate with the CorsairLINK software, which allows me to monitor things like power consumption, power output, fan speed, PSU temperature, and calculated efficiency. Right now I'm sitting at 79.42% efficiency with jumps every so often up to 80ish%, with the fan spinning at 0 RPMs... Wait, what? Yes friends, this power supply is so smart that even its fan knows when to stop spinning... er, start spinning. The fan on this critter doesn't spin up until the PSU reaches a certain load level. That means you have one less fan spinning in your computer to make noise. Which is a good thing, because my computer sits on top of my desk, just to the right of my main monitor. The less I hear from it, the better. Don't worry about it not working though, there is a test button on the unit that will spin up the fan so you know it is still functional. My plans are to only use this with a single video card... Currently a GTX 970, and this PSU is providing plenty of power to keep everything up and running. Power wise, I've got the aforementioned video card, a i7 6700k (not over clocked at the moment,) 32GB of Corsair Vengeance DDR 4 RAM, a Corsair H100i GTX dual 120mm radiator water cooler, a Samsung 950 pro 256GB M.2 SSD, 2 Kingston 240GB SSDs in a RAID-0, a 4TB hybrid Seagate HDD, keyboard and mouse of course, and a USB wireless headset beaming music to me while I write this all plugged into an ASUS Sabertooth Z170 Mark 1 motherboard, and the CorsairLINK software is telling me I'm using only about 65 watts from the wall, with the occasional jumps up to just under 100 watts. This PSU is doing exactly what it's supposed to do and not whining about it (fan whine that is).

### ⭐⭐⭐⭐⭐ All the power I will ever need
*by J***K on February 2, 2015*

As part of my new build, I decided to go with this Corsair power supply. Three things of importance to me when I was looking for a new power supply, is that it is capable of high wattage, modular (The last power supply in my previous build was not and lacked flexibility in cabling), and certified. This Corsair has got that covered, it is platinum certified, has detachable cables and a lot of them, and so far has steadily provided the power I need for my new machine. The fan is very quiet and the power supply looks good too. This is one quality power supply and has a great 7 year warranty. I did have a small issue with the ATX cables not wanting to snap in place and came lose a bit but I pushed it in further and it has held just fine since. This also comes with the Corsair link but unfortunately I could use it as it takes a USB connection on the board which I didn’t have available due to the case taking the ports already. I would have liked an option to connect the link some other way, but since I will use the ASUS software instead, it was a minor issue for me. There are eight (8) PCIe connectors and 12 SATA flat cable connectors that are as well made as the power supply.5 starsMy build (designed for future upgrade-ability and expandability) is as follow (using Windows 7 Pro, each hardware part, I will review separately)Creative Lab Sound Blaster ZAsus X99 Deluxe MotherboardCooler master Nepton 240M Water coolerCooler Master Cosmo II caseEVGA 04G-P4-2978-KR GTX 970 video cardKingston Hyper X Predator memory DDR4 2400 (16 GB)Samsung EVO 850 SSD Hard drive (main boot drive)Seagate Hybrid hard drive (secondary drive)Intel 5820K CPUCorsair HX850I Platinum certified Power supply

### ⭐⭐⭐⭐⭐ Replaced EVGO in Business Computer
*by H***. on December 9, 2019*

I am not a prolific computer builder, but did decide to take the task on when seeing that it's pretty common for business desktop PCs to pair better quality CPUs with so-so supporting components. My first build had an i5-4690 processor, ASUS Q87M-E mobo, Noctura high end fan and lots of case fans. Understanding that PSU quality is important, I did my due diligence and selected an EVGA Gold PSU that would do the job. Reviews were good so I thought I was good to go. The PSU failed within 1 year. I checked other users' experience and learned that others were having the same problem. I then went looking for a PSU with market for a few years. Research led me to buy the Corsair HX850i. It has been powering my computer for a year now. Unlike the EVGA, I have noticed that the power flow has been consistent. The EVGA had power fluctuations that I noticed but didn't connect the problem to the power supply due to my lack of PC building expertise. I know that there appear to be many EVGA SuperNova fans out there, but I am not one of them.
