430EX and softbox

[martin2day]

I have one 430ex and I'm looking for a softbox. X-lite seems to be to small.
I'm wondering if 430ex has enough power for http://www.bhphotovideo.com/c/product/42119-REG/Photoflex_XT_1SLD293_LiteDome_Q39_Softbox_White.ht ml or for http://www.bhphotovideo.com/c/product/135645-REG/Photoflex_XT_2MLD293_LiteDome_Q39_Softbox_White_.h tml

Which one suits better?
Thank you

With the double diffuse screen on, the 16x22 softbox and the 430 at full power can provide f4-5 @ 6 feet, iso100. Is that enough power for you?

It's just fine.
Thank you
