    Default Seasonic M12ii620 and S12ii620, Xigmatek Centauro 700W Related Question

    Hi guys,
    as I know S12 and M12 are basically the same with m12 being modular,
    I think of buying m12 620W or Centauro 700W, currently having some issues with my old Thermaltake cheap psu.

    but I am not expert on PSUs so I need your help to choice.
    I've a system with:
    Lots of Fans (7)
    A Gigabyte R9 280x Windforce it's 1100mhz
    so quite overclocked at 1.2V if I am not mistaken (just got the card).
    AMD FX 8320 @ 1.45v~~
    2 Memory Sticks DDR3
    1 WD Caviar Black, no optical drives.

    I did my researches quite well, this 2 are only that I can find as "good" and in my budget, Centauro and M/S12ii.

    Question is will 620W be enough for heavily OCed (200W~~) FX8320+R9 280x+Fans? I am not going to CF/SLI.
    PSU calculators give me 520, Recomended 670W psu, aproximately what I think of.

    So Summing:
    First Question is:
    Will 620W Seasonic unit be enough for my 550W~~ system.

    Second question is:
    if the Seasonic units can provide me 550W~~,
    Will they survive it for long time? (Seasonic Quality?!)

    Third question is:
    The Seasonic units doesn't have much protection, are they safe?
    I've seen the review here, but didn't find anything about it.
    In the other hand, Xigmatek one has all protections.
    so Question is, is Seasonic M/S12ii are safe?

    if:
    1st answer is NO, then second is NO. So should I get the 700W Xigmatek?
    if:
    1st answer is yes, second is no and third is no. It also means I should get Xigmatek I guess.
    if:
    1st and 2nd answers are Yes, but last one is no.
    What Should I do?

    Help me out

    Seasonic units are fine. 620w is plenty for a system that probably isn't that much over 450w in reality. The S12 and M12 are older designs, but perfectly servicable and well built. PSU calculators usually assume you're buying junk that wouldn't pass 80+ and severely overstates the actual power output it can sustain.

    I ran dual GTX560Ti on an 800w PSU with more fans (11, plus a water pump) and there was no stability issue using my Enhanced based unit that didn't score quite so well as the S12/M12.
    Intel i7-2600k with an XSPC Raystorm water block, 4x4GB Corsair Dominator, SLi Evga-GTX560Ti-448 FTWs, Asrock Extreme4 Gen3, Crucial M4 256GB SSD, Samsung Spinpoint F3 1TB HDD, powered by a Silverstone Strider+ 850 PSU in a Silverstone TJ-07BW case.
    I'm not buying EK GPU blocks ever again. (One GPU killed)

    THX!
    so now my only question will be,
    M12II missing some protections, should I be worried about those?
    it lacks UVP, and sometimes Undervoltage going to PSU can fry components as I know
