  1. They do rock, no doubt about it !

  2. Very nice indeed. id like to see a review of their 650W or 750W, 850W is a bit overkill for me…… coming soon?

  3. I like the sleeved cables 🙁 didnt know people like the flat ones more…..

  4. @ Mannucuna.

    Flat cables are better for routing, some cases have problems housing the fatter cables behind the motherboard tray. I do agree however, the sleeved cables look better, but most people dont want to be looking at them… especially in a windowed case. Its an industry wide move, Seasonic were slow to adopt them.

  5. its confusing because most of the stores dont list these as KM2 or KM3, its a complete guess when they dont include images or detailed information,. they should clearly mark these R3 on the box on the front.

  6. Yes the marketing is confusing. newegg has been shipping the for a while but had the images of the KM2 model.

    Minor nitpick about the review. It says “four OCP channels, two for +12V, one for +5V and another for +3.3V”

    which makes it sound like it is a two rail PSU. I believe it is a single rail and, like its predecessor, one of the two 12V OCP channels isn’t populated or used.
