Hi guys! I am getting this Pc

I5 4670k @4.2
Z87x d3h
R9 280x
Tx750 V2

So at first I was getting the TX 650 but because I'll give it to my brother so he could xfire his R9 270, It will need 500W but the Tx650 does not have 4pci e conectors, so is it overkill? I wanted to go for TX because I found a very cheap one.

Your question is very confusing... So is the tx 650 for the 2 r9 270's? or is it for the single r9 280x? but either way that is a good psu for either setup and is not overkill..

I am truly sorry, look I'll build a Pc with the i5 4670k and r9 280x
But because my brother has a R9 270 and a extreme 2 psu I was thinking about buying that one for me the 280x and if he decides to xfire his 270 I'll give him my PSU I first thought about the Tx650 but the 270 requires 2x6 pin conector, 2 will require 4x6 conectors, but because the Tx650 only has 2x6 I thought about the 750W but I don't know if its overkill :)

Na 750w isn't overkill... Those systems should run around 300-500w under full load... Most PSU's are most efficient at loads of 40-60%... So with those systems you should be in that range with a 750w PSU. Anything more than 750w could be considered overkill though - but I wouldn't get anything under 600w for sure.
