    It's a power supply that works. Flat black cables, and fully modular interface. Not much else to say here.

    Works well. Was impossible to find a set of custom sleeved cables here unfortunately. So I made due with extenders which did make cable management much harder.

    A bit overkill but it was the same price for a 750 watt, so I was just like... whatever. Great modular PSU. I trust Corsair in this regard. The only place it loses its star is in the wall adapter. When I was building, it just didn't feel like it was plugging into the pc securely. In fact it was a bit loose. After I was done building and put the PC where it actually lived, I had do make sure the cable was tightly curved so it wouldn't wiggle in the socket. This same thing happened with a work PC in my office. We ended up switching a to a different cable to plug it into the wall that was much more secure and a tighter fit. I may call Corsair and ask if they have a solution to this... The computer is getting power though. It works.

    I used this for my first ever build, and by far - this was the most challenging part to choose without and true hardware knowledge. After a massive research this was my No.1 pick, it has excellent efficiency, Corsair PSUs are known to be highly reliable and stable. I am not an electrician or hardware expert so I can't completely rationalize my argument, but anywhere I've looked - this averages as the best option for my build.

    love that I got this at such a great deal! I pulled the trigger on this thinking it wasn't going to go down any further in price, and I was right! It was back up to $190 when I last looked at it.

    Considering the price I paid for it, simply excellent.

    It hasn't blown up, that's a good sign.

    Also getting at least one 8+6 pin instead of an 8+6+2 pin would be nice so I don't have the little tangle of spare cable on an 8+6 pin GPU.

    PSU: I found it on amazon on sale. Never looked back. It came in a felt bag! Everything about it really feels high quality.

    Performs great. Cables are good. Wish it was a tad smaller.
