Hi, i have a:

Asus HD 7870 AMD Radeon DirectCU II Graphics Card

coming and want to know if my PSU, 400W Xigmatek can take it

if you need anymore info on my other components then ill post em, i would rather know now and order a more powerful psu than have it come and burn out my rig

yes a 400 watt PSU could, depending on the rest of the rig - but i doubt that one will.

it might take it, you will discover that fast. I would not take the risk tho, get a cx600 instead, Corsair

what budget do you have?

because it just might surprise people but there are actually better PSUs than corsairs out there and esp the CX series.
