Buying new PSU soon. I round up this two;

..like the unit but i'm having problems with actual dimensions(cant find them anywhere),XFX site only shows 750w, but dimensions dont make sense.Does anyone can tell me how big is it ?(psu i'm using now is 6.22'' and i got only about 1/4'' to spare)
This is my " numero uno" choice;

Thanks!

  1. Best answer
    xfx 850(made by seasonic) is one of the best ever 850 watt units ever made only rivaled by the corsair hx850 ,antec sg 850 ,antc cp 850 and seasonic md12II 850(basically the xfx 850)

    the ultra is crap

    if you using an atx psu any normal atx psu will fit its a standard size across all power supplies in the atx form factor
  2. The XFX 850w BE is light years better then that Ultra X4.
  3. WOW..i'm a bit surprised by how high you guys rate xfx,i have to take your word...XFX it is.
    Got to tell you ,i'm not going to be a happy camper if i have to buy new case or modify existing one

  5. I think i'll be fine,thanks guys for all your help,obsidian86 you had the quick draw
  6. XFX 850W is 6.75" long. While the Seasonic M12D-850 is 6.25. Even tho as said they are basically the same power supply there are a couple differences. The M12D is listed as a as having dual 12v rails and comes with a 120mm Sanyo Denki fan, the XFX is listed as a single rail with a 135mm ADDA fan. I would guess that the larger fan is the reason for the extra depth.
