    I’ll admit I suffered a brief episode of shock and awe when I opened these power supplies. I was sure I had selected the wrong thing. My computers are all-in-one. touch-screens and there is no way something like this would fit inside them.

    I really thought the 650 was going to last forever when I got it a few years ago, and now this. These haven’t changed much (at all?) and the last one just chugged away until I needed a bigger one so it was a no brainer to me to go back to Corsair & get the next size up.

    I bought this as part of a brand new gaming build. Admittedly, I had never built a PC before. I am SOOOO glad I went with this product. It is truly modular, has a ridiculous amount of power cables included, and is future proof. I literally did not even use half of the included cables by the time I was finished building. This means when I decide to add more hardware in the future, Im covered. This is so much easier than individually sourcing all the SATA cables youll need. This kit has you covered and had plenty of power. Do yourself a favor and spend a few extra bucks for ease and peace of mind.

    Like some other reviews on here my PSU arrived DOA. Not even a glimmer of power to the motherboard.

    Good product overall, would like to have known on the packaging that it was three daisychain PCI express 6+2 pin Connectors. So then I didn’t have to spend an extra $150 on cable mod. The connecters aren’t sleeved.

    Im new to PC gaming, but had a friend build a PC for me. I havent had any issues with the PSU yet, it seems to work quite well.

    Easy install... PS is really nice, its just that the cables within the PC are difficult to trace & replace with ones frome the new PS. So far Great Power Supply. Changed from a 600 watt to a 800 watt. Feel safer knowing I now have ample power for pretty much any peripheral I may come across.
