I have a GTX 260.

And im getting a new PSU because i need more power..

Corsair 650TX

Antec TP750

They are the same price, it looks like TP 750 Has more amperage than the 650TX but it is multi 12v, while the 650TX has a single 12v.

Antec TP750 = 62A
Corsair 650TX = 52A

Which is better ? and better for future SLI?
