    Arrow Seasonic X-650 650W Review

    Two weeks ago, I reviewed my first ever 80 Plus Gold certified power supply. Since then, I've been anxious to see more such units, wanting to know if this level of efficiency is possible to find at the same time as ultra high performance. Well, Seasonic read my mind and has sent me one of their new Gold units, the X-650, to play with.

    Tomorrow is Thanksgiving Day in Canada. Will I be thankful I met this unit? Come on in and find out.

    Hmm... that chip switches between FM and PWM modes during operation.
    That is rather interesting... Don't think I've heard of that in another PSU before.

    after read the X-650/X-750 [H] is there a X-850/X-1000 there? looks like I don't have to against module design since the efficiency and voltage didn't drop at the "X" unit

    The most powerful PSU Seasonic has made is the M12D/S12D 850W. I doubt they'll be coming out with more powerful versions of the X series simply based on previous behaviour.

    I don't understand why Seasonic don't make a KW unit? I should say almost all of PSU manufacturers have their KW design but Seasonic still not? high efficiency, good ripple and voltage regulation should help Seasonic to push higher wattage without much problem. at least they should have a unit support 3 way SLI

    A 750W or 850W PSU is enough for most 3-way SLI systems.

    I can't understand why anyone thinking about 3 way SLi would care that much about efficiency anyway? Considering that 3 way SLi doesn't even scale that well...that is some pretty horrible efficiency there in itself.
