i was looking at teh last psu and saw on the thermaltake website it had no PFC and had no idea what that ment so i searched it on google and saw that it was really bad not having one, even illegal in Europe.
but only the w0031 has no PFC but teh w0032 does and there is no difference except that. however i cant find the 32 on newegg. its a really good price ($20 cheaper than teh other 2) but now im looking more at teh second onw

What is the PFC? (Power Factor Correction)

Many loads are highly inductive, such a lightly loaded motors and illumination transformers and ballasts. You may want to correct the power factor by adding parallel capacitors. You can also add series capacitors to "remove" the effect of leakage inductance that limits the output current.
Non-PFC offers around 0.5~0.6 PF (Power Frequency), 40%~50% power lost.
Active PFC provides more efficient PF(Power Frequency), 0.95~0.99, it means only 1%~5% power has gone.

========================
Try everything...
Do not be afraid of failure, for this is how we learn and grow...
Live life to the fullest...
Do not regret what you have not yet done!!!
