PS are an odd thing...
The "Watt" rating alone is not a good indicator of it's ability.
Check the 12+v rail which should total at least 24a with 1 vid card and 34a with 2... and look for Reviews. The single most overlooked item in a stable OC is the PS!
On the fan size, there are many aspects to the sivs and how many.
Larger usually equals higher volume with less noise. Dualy offer the pluss of a push pull. The effect of quality cooling can equate to a more stable PS at high loads because with themp increases the stability drops. So good case air flow not only keeps the MB/CPU/GPU etc.... cool but effects the PS temps and stability as well.
