use at least 4kw real power, not on the plug, i mean installed power not on the label on psu,
you can use 4 x 1000 w 80+ gold psu, you can use add2psu card for it,
remind it more installed power means more safe and stable power feed.
also you can use 2x 1200 watt and 2x 1000
Well, 4x 1000w PSUs is a good option, I can get those for not much more $$.
So do I need to connect all 4 together with add2psu's? Am I able to do that?
And I will do the same question as the post above. How do I set the risers? All of them in the MOBO PSU or conected to the PSU of that respective VGA???
