    I know saying this for a PSU seems odd but the packaging was amazing. The cables are in their own nylon bag, the PSU was in a velour drawstring bag and everything was packed in dense foam padding. The PSU is well marked as to where things go and comes with a set of black screws. I was impressed at this point. Once I had it installed and the motherboard cabled up, I powered things up for the first time. This Corsair RMx power supply Is absolutely silent when just using my Hackintosh for work stuff. Once I start using much more CPU and need more juice the fan starts to run but its still very quiet. This is really an amazing PSU. I would (and will) recommend this RMx series to anyone and if I need to build another PC, I WILL be buying one of these.

    Ive used Corsair power supplies in the past and have recommended them to friends because I love them. This 80+ gold model increases the power efficiency over the other Corsair it is replacing as well as giving just a little extra power headroom which will be needed after adding another PCIe card.

    I ordered this item and immediately installed it the first day. The modular install - only needing to plug in the cords you intend to use - is really nice, but didnt save that much space in the bottom of the tower since the cords dont really bend quite as easily or immediately out of the unit.

    Was looking for a quiet 800 Watt PSU and this was the one. Also slightly smaller than expected! 10/10
