Need better WRAP.2C Power Supply for 2 wireless cards?

[pcatiprodotnet]

What is the best PSU I can buy to support wrap.2c with 2 wireless cards?

I need it to power the wrap plus two(2) of these wireless cards: EMP-8602 400mW tx@750mA.

Possible PSU Solution with far more Amps than regular wrap psu:

I'm not an electrical engineer; if this won't work or I'm missing something please advise.
Thank you,

you need 2x 750 mha for the cards that is 1,5 ah
and 1,5 ah for the wrap
so you need a adapter with at least 3 ah
