    In my country (The Netherlands), this is the cheapest and one of the quietest PSU's that is fully modular. I took 620W for SLI to be optional in the future. The cables are all black, so no nasty colours interfere with my colour scheme. Otherwise, it's a PSU and it does it's job really well.

    Great and reliable power supply. Wondering how it's taking all of these overclocks extremely well.

    -EDIT- Eh, this PSU, while great, has started being a bit of a problem, as they started clicking around 6 months of usage. While is is still extremely reliable, passing the OCCT power supply test for over an hour with overclocked equipment, the clicking sound persists. Bet that not all of the S12II has this problem, but just saying.

    Much better and quieter then my 600B. Seasonic never fails to deliver. All cables are black, except the 24 Pin has the mesh tubing around it and you can see some of the rainbow wires in there.

    However nothing it perfect, the only thing I don't like about it is the cables are somewhat stiff.

    Reliable PSU with good power rating. The only downside is that it's not modular.

    Just a good PSU. Delivers enough power for all of my components. It's modulair so that's even better. It quiet as well so, just a good PSU.

    what i have in mind is the seasonic m12ii(fully modular) but the store i went to said they are out of stock. i am also okay with this one since the Psu placement is shrouded in the tecware alpha

    It works. Got nothing in particular to say about it. I had a bit of trouble with the cables but it was to be expected from a non-modular PSU.

    I can't complain about SeaSonic. Good PSUs with good warranties.
